[@steviebattle5495]

Hear me out: Mass Specific Force. You can look into it and find a lot of details. But basically, in order to sprint* faster, one must be able to put enough force into the ground to offset gravity. How gravity affects each individual is relative to their own specific mass. This means sprinters should be as strong as possible, while also remaining as lean as possible (relative to their own unique build). This is done in the gym. Sprinters should strength train, as opposed to training like body builders: Use low reps. The sprinter should avoid eccentric movements in exercises like the deadlift, because lowering the weight causes fatigue and therefore hypertrophy, where the muscle grows. Focusing only on the concentric movement allows the athlete to gain strength and recruit more fast twitch fibers, and avoid muscle growth. A sprinter's ground contact time and stride length are the result of putting more force into the ground. The gym becomes useless for sprinters when the focus is on hypertrophy and growth as opposed to strength. BUT strength is crucial to running fast. If you can't put force into the ground, you can't offset gravity, you can’t* run fast

[@steviebattle5495]

@@justjumari yes, but specifically with how much force is applied to the ground

[@ksweden3455]

That is true but I will argue all day and night about eccentric movements..much more force is coming from eccentric, just doing concentric work won't make you faster for sure, you know that muscle works in isometric,concentric and eccentric,,so you need to train all of them..during sprinting hamstrings load are extremely higher in eccentric during lengthening and pre touch phase to the ground, most of the injuries in muscles during sprints, acceleration ina all sports are happening during eccentric(lengthening) work of muscles,,,one rule in season or near competition,game or whatever is that doing just concentric work is OK, doesn't make you tired,so recovery for next day is faster, not microtearing muscle with eccentric work that is fine.. but all the best sprinters or other athletes with great power in jumping,throwing,kicking etc are extremely strong in eccentric movements. Specially sprinters muscles needs to stop moving concentricaly so lengthening in eccentric phase(absorbing force) and stopping in isometric phase and again in concentric phase...because of that eccentric isometric phase is much more relevant to speed and power...all the best and explosive,fastest guys are the strongest in eccentric and isometric phase

Just my humble opinion. As a senior sprinter who competes regularly in the Senior Olympics at the National level and has been sprinting probably longer than most of you are old, I can tell you one thing for certain: You get fast on the track, not in the gym. Use the gym to supplement your track workouts with such things as strength training; plyometrics, core work; medicine ball work and resistance band work. You need the gym for overall strength, so your body is ready for what sprinting is going to put it through. Sprinting is controlled chaos and the gym work helps control that chaos. Lifting weights is a small portion of all the training you need to sprint well. It's all about good form, force production and who slows down the least. BOTTOM LINE: To run fast, you have to run fast! JMHO.

As a sprint coach myself, it’s good to see another coach that understands this. Now that I’m over 40, I’ve started training for an ultramarathon. But I still sprint regularly too. I dropped my gym membership and dropped the static stretching. My only strength work now is mostly just isometric stuff, low volume. I feel like my legs have a much more springy type of feeling now, more responsive to impact. I trained a few decent sprinters without the emphasis on weights and it has been rather successful. Crazy thing is, I’ve gained muscle mass this past year.

I am 50. Train olympic weightlifting. Sprinted max effort for the first time in my life last May. First max speed was 37.7 km/h. I am starting to switch from distance running to sprinting as my other sport now, and just working on accelerations twice per week. I can finish 30m somewhere under 4 seconds, with max speeds recorded before decelerating at 30m reaching around 30 km/hr. Last summer when experimenting with this I noticed I could maintain max speed only about 60m, so I am not saying this is competitive. I am just saying that, if you have the genetics, then the strength training is going to make you stupid fast. I just don’t know how to find people to help me learn to not sprint like a runaway freight train. I think some people are just not goi g to respond much at all to strength training with respect to speed development but others will respond a great deal.

[@Bombsuitsandkilts]

Sprinting is about power output. Increasing 1 rep max (moving slower with higher resistance) is very highly correlated to increasing power output more so than training to move faster with less resistance. (BIG) BUTTTTT! the farther you move away from the specific force and speed range i.e. slow grinding reps, you lose a lot of neurological ability to fire muscle quickly. Try things like post activation potentiation which is 1 or 2 reps heavier than 85% 1 rep max into body weight plyometrics (not competition sprinting, because you never want to alter your sprint form) and power snatches of around bodyweight on the bar. Moving 2x bodyweight can be usefull but you know what's more useful, moving 2x bodyweight fast, so never slow down weights in order to move more weight. It's hard to check the ego sometimes.

[@TheGudeGym]

I’m a thrower so the weight room is more of a factor but I agree with this take. Best advice I ever got was from Dan John “Throwers throw, sprinters sprint, hurdlers hurdle.” In throwing when generally know what levels of strength are necessary and generally more number based rather than x body weight since being too small hurts performance. It makes perfect sense to me to use more body weight measures of strength values for sprinting. In my opinion 315 conventional deadlift and a 275lbs squat to full depth would be plenty of strength for a sprinter. I wouldn’t see a 500lb deadlift helping a sprinter like it would a thrower. I would add in short hill sprints to the list of exercises you mentioned too.

Tendons and joints can be strengthened and loading all parts of the body is much more powerful than strengthening your body in one dimension. Different planes and movement speeds. Isometric and plyometric exercises are super good for explosive athletes but also still training your compound lifts with a more speed intent through the movements will really make the difference. Lift heavy weight fast, as apposed to lifting heavier weight slow. You want to dominate weight explosively, then move the weight up.

One thing as well that confuses people is the size of some of these elite sprinters. Asafa Powell, Donovan Bailey, Linford Christie etc... are massive. But it's because they are genetically gifted and respond very well to strength training from a hypertrophy point of view. They didn't put on that much mass for speed, they just happened to be jacked dudes. Look at guys like Lyles, Christophe Lemaitre or even Andre De Grasse, they look like twigs but are as fast. And then you have guys like Harry Aikines, built like a silverback, front squatting 200kg but still can't break a sub 10 sec. Ultimately, mass will slow you down, that's just physics. You need to find a right balance specific to your body type.

[@Ninjaclips4894]

Mass Specific Force is a concept that relates to sprinting and how an individual's mass affects their ability to generate enough force to overcome gravity. In order to sprint faster, sprinters need to be strong and lean, relative to their own unique build. This is achieved through strength training rather than bodybuilding. When training for sprinting, it is recommended to use low reps and avoid eccentric movements in exercises like the deadlift. Eccentric movements, where the weight is lowered, can cause fatigue and muscle hypertrophy (growth). By focusing on the concentric movement, sprinters can gain strength and recruit more fast-twitch muscle fibers, without promoting muscle growth. The ability to put more force into the ground is crucial for sprinters to improve their ground contact time and stride length. By focusing on strength training and avoiding excessive muscle growth, sprinters can optimize their ability to generate force and offset gravity, ultimately allowing them to run faster.

[@martmuru]

The concept of strength training is often misinterpreted. By lifting heavy weights, you enhance your maximum strength limit, which in turn increases your capacity to generate more power. Speed isn’t trained in the gym; instead, it’s developed through maximum speed movements without load, such as sprinting. There aren’t any “transfer” exercises that are worthwhile. It’s as straightforward as that.

[@justjumari]

Sprinting is an equation of force and rate of force output. Lifting weights will increase your max force output as long as you stick to low rep, explosive movements. The weight room is half the battle if you know what you’re doing.

The problem with lifting is how much fatigue it produces.

Strength to speed correlation is not linear yet. Law of Diminishing returns. Strength can be a limiting factor to your power. Power= Strength x Speed.

I know I’m kinda late but athletes should be lifting to strengthen their muscles when running, it’s a difference between athletic training and bodybuilding training. Athletes train and workout for an athletic build, for instance DK Metcalf. The more force you implement into the ground the faster you move like the harder you move your arm (with the right form) the more force goes into the ground. Now their should be plyometrics involved to help with jumping, stretching to help loosen muscles, and running to help with building stamina and agility.

[@Kencio26]

What matters is that you can produce a lot of force quickly. If you‘re only in the gym, you have a lot of strength. Due to slower contraction velocity in training, your acceleration will be better than your top speed (slower, more force vs faster, less force). If you can get your maximum voluntary contraction up while also increasing the ability to contract a muscle really fast, you will become a better sprinter.

I agree with you here. In my 20's (I'm 35 now) I was a professional boxer and if you can please forgive me talking about myself, I was a hard puncher, and explosive. The only other training I did before boxing was gymnastics (4 years) and my boxing coach told me I had good body control which he felt was the main reason for my power. I began to lift weights somewhat and even though I got stronger it didn't really help my punching, and in fact I was probably the weakest one in the gym for my weight. But now when I talk to kids at the gym I tell them to learn how to relax and to "flow" when they throw a punch. I know it sounds ridiculous but it works, and think about it, who teaches a cheetah how to run? They don't do anything but run.

[@sjphi1953]

They also stretch a lot, which keeps them springy.

[@deehenry6192]

This greatly depends on what the needs, limitations and deficiencies are of the athlete. If an athlete is already fast and has been most of their life most likely due to a genetic disposition then that is totally different from an athlete who is limited. If an athlete is deficient in power, speed and/or body composition then you can have them sprint all day and they will not be fast. You must have a foundation or develop it or you will only get so far. Most athletes overtrain in the weight room and do a lot of body builder type exercises. Deadlift and pull ups are directly correlated with top sprinters. These two exercises are great indicators of posture chain and core strength. Another thing is in order to get faster you must train and sprint at full recovery. Most do the opposite.

[@crazylongjumper95]

Strongly agree with you bro. I usually have a 8-10 weeks of pure strength workouts (when I am at the gym) during the very beginning of the season, always working on my technique on the track with so many drills, to then pass to 1 strength sesh to the gym, in which I try to execute quick movements, preferring lots of plyo workouts, having an important force structure done before. In my humble and personal opinion, I think in way too many cases, both strength and plyos are overused, I think this is due to lack of knowledge by many coaches (you can't do high volume plyo exs at the very beginning of the season, nor doing only max strength sesh at the gym all the times).

[@justjumari]

Definitely do some strength phases about 2 months out the year. I see everything you say and I agree !

Plyos are important but squats, hanging leg raises, and RDLs with straight legs are important to prevent injury.

Great content! Also has a lot to do with neurological recruitment of different types of muscle fibers. Mark Asanovich talks about this with different types of athletes as it relates to sport specific skills.

[@matthewgraham2546]

This has always been up for different opinions. I was a sprinter and a running back in 1968-70 when we ran yards. In football we backs would always run toward the big guys because they couldn't run fast or far. Speed is something you are born with either you have it or you don't, it was called muscle retraction if I recall, my brother two years younger had it also. Other than practicing your start there was no training for the 100, it was just wide open for 9.9 seconds. We trained for the 220 and practiced the relays which our team set a FHSAA record. The long distance runners always looked worn down to me and the big boys were in the bleachers. The other thing I wouldn't do was stretch, it seemed to me a lot of those guys would pull up lame especially after about 110 yards. Matthew Boling is no joke, that Dude is fast. Good video subject.

[@BigLadGreen]

The best exercise for sprinting is sprinting. Who would have thought.

[@thku4grace]

Its not just lifting weights. In order to train and compete effectively, a sprinter will lift primarily, but not solely, in the offseason because recovery times will greatly affect the nature and quality of time done in the season sprinting. Also, time spent lifting will also include smart recovery methods, including lots of ice baths, stretching, proper nutrition, quality shut eye, and massage.

[@Telefails]

At 15 I weighed 130 pounds and I ran a 4.81 40-yard dash. I'd never done a single deadlift, and I'd only squatted maybe 4 times in my life.

[@roderickclerk5904]

Doesn’t mean you weren’t decently strong. If you did some deadlifts you’d probably be pretty good at them, but like you said you didn’t need them to be fast. I try to make my strength training and running compliment each but of course running and sprinting is more important. Also do not get inflexible. Never go multiple weeks without getting good stretching

[@jong3397]

Another element is doing enough strength training to stay health or recover from injury vs increasing strength. Many NFL teams have moved in this direction. The body can only take so much and the goal is to stay healthy so you can maximize your sprint/track or football training. This is exactly why Tom Brady told JJ McCarthy at Michigan. Tom told him to stop or drop greatly reduce the strength training especially during the season and focus on the on the field or in this case on the track training.

[@jackcarpenters3759]

yeah 1.6x bodyweight squat is exactly what the research sais. After that there is not much improvement. There was also research that sais slow sprinters can do 1 minute of planking, fastest sprinters can do 11 minutes of planking. There was some correlation too.

Preach my friend . Low transfer once you get vast 1.5 and for the planking having a good core can help with transfer from the ankle to glute so that’s definitely good!

At my best (only ever recreational, not a competitor) i felt everything you said and did most of what you said to get there. The proprioception training, the 1.5-2x bw lifts (I was doing 2x), due to previous injuries i was focused on a lot of rehab stuff and those things made me way more elastic and tendon strong. Running was like cutting through the wind, pure mechanics and it was like i can change gears - start and stop, cut an angle at will. Beat running shape i ever been. Unfortunately i atarted sprinting a lot for fun haha like warmups and such, eventually one day i just got injured again and i havent been the same since. i was also been a bit lazy to go do the rehab work.... but i am now, and cant wait to be super agile again.

I never really monitored my sprint speed, never sprinted, just pushed the numbers up, well, at a family reunion an opportunity arose to test my training, I never in my life moved as fast, it was exhilarating! Weight training correctly done most definitely increases sprint speed, you don't need as much as many people think though.

[@justjumari]

[@jackvandyke]

Just adding this for a counter point on going above 1.75x BW causing negative feedback and compensations - Randy Huntington, Olympic coach of Su Bingtian and other athletes, has said in a podcast (IASC) that he wants his sprinters to squat 2.5x-3x bodyweight. I think the main point is prioritize sprinting and plyometrics ahead of strength numbers beyond 1.5x BW or you’ll be turning into a powerlifter. Oh, and there are studies showing athletes who can’t squat 1.5x their BW didn’t see improvements from plyometrics - so you better get to that strength number!

[@justjumari]

I think you should look into a video called “how strong do you have to be by PJF podcast” he explains some of my points much better I think you’ll get my standpoint

[@justjumari]

There are some studies but there’s also ton of olympic sprinters and nba players who can sprint and jump out the gym who have stayed hundreds of times that they have never touched the weight room. So we have to question the narratives these studies try to bring in and the type of athletes they are using at studies. Random guys who never worked out? Or 10 years of training mainly slow twitch then all of a sudden some plyos? A lot of questions to be asked

[@jackvandyke]

@@justjumari high school boys were the ones in the study - a good portion of your audience I’m guessing 😂 I appreciate and enjoy your content btw, keep it up. We definitely agree on the main principles here (prioritize sprinting over everything), but I disagree with negative effects over 1.75x. The podcast just references no positive effects on max speed over 1.75x but nothing negative. What about acceleration/block starts? I reference Su Bingtian as he clocked the fastest 30m and 60m splits ever in Tokyo. I just don’t think writing off improving strength beyond a certain point is good as it seems to be athlete dependent and not a general rule. As you referenced nba players and Olympic sprinters, I’ll reference NFL players. You see some dudes running the 40 at 4.3 and under who probably only squat 1.5-1.75x and then you got guys like Tyreek Hill and Alec Pierce with massive squats/deadlifts putting them at 2.5x and over. Some people benefit, others don’t.

[@ArthasMal]

I think it's all about balance. When you see that doing more strength work interferes with speed development because of fatigue or lost time on specific work (in this case sprint and drills on track) then you need to reconsider how much volume you can allocate for each physical feature. Definitely depends on phase of training.

If I’m not mistaken speed is force x acceleration. Therefore strength would be a main component if the athlete isn’t as strong but can hit the ground fast.

"Knees Over Toes Guy" teaches something like this. He's very flexible, especially in his legs, and he doubled his vertical jump in his 40s without putting on much mass. It's definitely a power-to-weight ratio and range-of-motion thing, as well as neural-capacitive speed AKA mind-muscle connection. Training for strength isn't a downfall, but carrying more mass that your increased output doesn't offset IS. After all, force, mass, and acceleration are all related. If you can reduce mass and maintain the same force, you increase acceleration. If you increase mass and require the same acceleration, you need more force. The flexibility training so you can retain your range of motion helps reduce wasted energy by making your joints and ligaments less resistant. They also allow you to produce power over a broader range of motion/longer time per stride or jump.

posterior chain lifting helps, but wont help with hip flexor (turnover) or a clean foot strike (top speed). lifting is a good recommendation for improvement because most people just dont naturally have a good foot strike and there isnt much room to improve what you have naturally in terms of stride mechanics. you can always keep pushing up your squat and power clean numbers.

I believe it is more of how you do it. Lifting must be explosive to encourage explosive movement. If you have to lift lighter to move it faster than that is what must be done.

[@Mrwiseguy101690]

I was also slowest when I was at my strongest. I think my issue was with mobility though, and our strength program also wasn't that good so I had developed some inbalances. Being strong is important for sprinting, but what people overlook is that you have to be strong within the full range of motion. During a sprint, your muscles go from nearly being fully stretched to fully flexed multiple times per second. Neglecting the full range of motion when weight training will hinder flexibility, cause mobility issues, and increase risk of injury while sprinting. Note that I'm talking about weight training for the purpose of developing pure strength. Sometimes it's fine to half-rep or quarter-rep if you're primarily focusing on rate of force production. You just have to make sure that you're not neglecting the full range of motion in that specific muscle, and that it is ultimately strong enough to comfortably go through the rapid stretch shortening cycle during sprinting.

As a coach, when creating periodization for my sprint athletes, i put 3 sessions of strength workout per week in their 4 weeks GPP - the objectives are to develop their general strength (whole body) plus activation, physical, posture & of course injury prevention. During the same session of strength training i always combined it with acceleration or speed workout before cooling down / end of session. The sessions comprises of weight training, sled pull etc. The non strength training days, i put plyometrics and speed endurance exercises. Entering the SPP, i used complex strength training methods, sub maximal strength, resistance band, sled pull / push on their training programs plus acceleration & speed. Plyometrics & speed endurance during the non strength sessions.. During the pre competition phases, i then reduced the strength sessions to only one or two sessions per week just to maintain their main muscle strengths... And focus more on techniques, speeds, speed endurances, blocks, accelerations etc... I found out my athletes improved a lot... In summary, i think its all depends on how we planned, combined and created the training programs/ meso, micro etc.. And i agree... Weight training alone, will not increased athlete's performances.

For me I'm really skinny and can only get up to about 1x my bodyweight in the major lifts, though I am really reactive and get 50 cm or higher easily doing pogo jumps. Off a step approach I can get about 85 cm. In my case I definitely need to get stronger.

I was a good sprinter in HS. Then I hurt my knee and focused on lifting for a year and could lift a lot more weight. When my knee got better I fealt like what you are saying is true. The weight lifting streghth didnt help me at all.
