Dude, thank you so much for this series. Seriously! I've been training for somewhat around 2 years now. I've also been feeling insecure and overwhelmed with the whole thing since the start. Every time I tried to inform myself in the internet it just got worse. There's just so much information and opinions and I didn't know what's right, what's wrong, what's important and what not so much. I had no idea what to do. I've just had personal trainers make plans for me every now and then and then followed them. I didn't even know whether they were really working or not, but was scared to modify them because I didn't "understand" them. And when I did modify something, I didn't know how and why to change which things, so I wasn't even sure whether the change was good or not. A few months ago I found your channel and discovered this series a little later. I think you may have changed my life! (at least a bit) These videos have been very informative and helpful to me. They were easy to follow and understand and it all made sense. You seem very informed, intelligent, humble and you have a great body. This and the fact that you're so interested in science and take your information from scientific research or back your claims up with it makes you seem very trustworthy! After watching this series I think I finally know and understand the basics. While watching I also realized that I already know more than I thought, I just wasn't sure whether my "knowledge" was right or not before. But now I feel competent and confident enough to start working out by myself, make and modify my own training routines, listen to my body and experiment without the overwhelming fear of doing something "the wrong way" (turns out I already was doing a lot of things the wrong way anyway, so I can change that now). I'm excited and motivated to try what I learned! THANK YOU!!

Safety/Form: It is correct that proper form involves control of the resistance through the entire range of motion. However, proper form is *not* necessarily a full range of motion, and there are reasons to specifically avoid certain ranges of motion (for both safety and efficiency). Safety is really about one thing: minimizing the *force* involved. Excess force causes injury, but we don't know what that threshold is until we exceed it, which is too late. As for repetition cadence as relates to *only* increasing muscular size/strength, it doesn't really matter. Stimulus for adaptation in size/strength is based on overload, meaning placing an increased demand on the target musculature. In practice, this is a matter of performing strength training activities to a high degree of *intensity* (muscular output relative to maximum possible muscular output at a given time). When strength training activities are taken to the same level of *intensity* and controlled for equal Time Under Load (this is important!), the results are pretty much the same. The "super slow" repetitions that take 10 seconds or longer (which is really a moderate cadence, not a notably slow one) are not worse for size/strength. The studies done that come to such conclusions make the mistake of comparing cadences based on mechanical work (number of repetitions) rather than Time Under Load, but the ones that standardize on Time Under Load find no appreciable difference. The misunderstanding of mechanical work is a common one, and we'll see this lack of physics knowledge come up again. As for cadence notation, those of us who have used notations as such don't quite write it that way or with those categorizations. The four phases of a repetition are (in order used in cadence notation): lifting (concentric), transition from lifting to lowering, lowering (eccentric), and transition from lowering to lifting. Understanding these phases is important, as the proper execution of a repetition has specific considerations for all of those phases for every strength training activity. As for "specific goals," there is only one goal: to increase muscular strength. "Power" is an invalid goal, because muscles do not produce mechanical power, they produce force. There is no such thing as "explosive force", there is just force. Speed of movement is a byproduct of the force applied and the amount of mass, so someone can be "exploding" (contracting as hard as possible) with *very* slow movement. It is a common mistake for people to attempt to use mechanical work/power as metrics of muscular output. This comes from a lack of understanding of physics, which is (unfortunately) very common in the exercise industry. This is reinforced when he says "eliminate momentum." Whenever an object (mass) is in motion, it has momentum, so it cannot be eliminated. Much of what he is saying is based on the mistaken approach of assuming that the goal of strength training is to lift the weight. Nearly everyone makes this mistake, in assuming the goal is to do something to the weight with your muscles - that is *demonstration* of strength/fitness. *Development* of strength/fitness is doing something to your muscles with the weight. So what should people actually do? When I instruct people on performing repetitions, I advocate a general cadence of *no faster* than 4 seconds lifting, 4 seconds lowering, and 2 seconds in transition from lowering to lifting (this phase of a repetition has the greatest risk for injury due to the physics and physiology of that portion of the activity). It is common for people performing proper strength training to use cadences anywhere from 4-10 seconds each for lifting and lowering. These cadences don't make the training more *effective* though, but that is only one of the criteria of proper strength training. Proper strength training also aims to maximize *efficiency* and *safety* , and these criteria are where proper cadences make significant differences.

[@loveartist5043]

4 : 0 4 : 0 might be best for preventing injury. Force = mass x acceleration. So if your going slow you have less acceleration and less force on your joints. Thanks for the informative video 🙂🤙

[@mario8833]

I think that could be right, but probably even with just 2 or 3 seconds of eccentric, you are slow enough. Also, I think the concentric is not that harmful if you handled the eccentric correctly and are in an optimal position to push (or pull or whatever) so you can be faster. For example, I train in some compound movements with maximal intent on the concentric in order to develop strenght and explosiveness (lifting heavy weights with maximal intent increase power even if the weight is not actually moving fast) but my eccentric is every time at least 2 seconds in order to control it and being in a strong position. If you have like 80%RM or more on your back during a squat, getting ass to grass in just 1 second is too fast, and you're likely going to miss something. If you slow down, you have the time to think about your cues, and you'll find yourself in a strong position in the bottom; from there, you can push as hard as you can because you are tight, with the weight correctly on you feet etc.

[@visheshdeepgautam]

You have to get 2 seconds contraction as a general guideline... But If you do Only Free weight exercises then 0 seconds pause is the way... Like Bench, Squat, Barbell Curls. But Supinated grip Lat pulldown, rows, Cable Pushdowns may benefit from 2 seconds contraction as the weight tension is still on to the muslces and not the joints as in most free weight exercises... Still there are exercises with free weights where there can be 2 seconds pause at contraction like Bent over fly, Lateral Raise, etc. As we have three types of strength, Concentric, Static & Eccentric... The exercises providing Static strength may be beneficial without getting stress at the joints.

From study cited: Findings suggest that training at volitionally very slow durations (>10s per repetition) is inferior from a hypertrophy standpoint, although a lack of controlled studies on the topic makes it difficult to draw definitive conclusions.

[@harrisonwalker6902]

Watched/listened to one of jeffs more recent videos/podcasts (can’t remember which I heard it from) he cited a paper which showed that a FAST concentric on a bench showed an increase in strength gains compared to a slower one, but with basically identical hypertrophy. Just a little tip ;)

[@misterkeebler]

I see pros and cons to 'enhanced eccentrics.' A possible pro would be it increases Time under Tension, but i hesitate to say pro since i'm not aware of a study yet that shows a strong correlation between time under tension (isolated from other factors) and hypertrophy. But i do believe it can help people attempting to establish a stronger mind/muscle connection, which is especially helpful with some body parts people have trouble activating, such as lats. On the negative side, this extra eccentric time is robbing you of energy that could be spent on an additional concentric rep or two, perhaps a few reps. Also, your body can handle a much larger load eccentrically than it can with concentric, so you aren't really challenging the muscle either. It could almost be considered busy work, but not the type of stress that would elicit an adaptive response . So you have to know what your goals are for a particular exercise and experiment. In most cases, i would rather have a shorter controlled tempo let me hit 11 or 12 reps, vs a longer eccentric where i can only hit 8 to 9 reps. It definitely wouldn't hurt during your last set when your energy and performance are going to be lessened anyway, and you are trying to maximize amount of work performed thru different pathways.

[@vivs005]

@Balder van de Vijfeijken I don't know how well developed your chest or your mind muscle connection is. But you can certainly feel the squeeze in chest even with properly retracted shoulder blades. If you're forcing your shoulder blades in without focusing on chest, you're doing excessive tricep work. A good mind muscle connection with chest does makes you feel the squeeze in chest.

Can you do a video on triphasic training please ? I heard it's great for increasing 1RM specifically. And it makes you more injury resistent because of the eccentric and isometric phase

[@samsaw11]

Hey Jeff, great video as usual. Thanks for breaking down tempo. Just a few questions: 1. If tempo between 0.5 and 8 seconds is statistically insignificant for hypertrophy, why would you alter tempo at all? (apart from the fact that you'd want to control technique and train for sports specificity) For the average Joe, would it not be better to just reserve the energy you would use from slowing the tempo and just simply perform extra reps for more optimal muscle gain? 2. A lot of the time powerlifters and olympic lifters train by pausing at the bottom of their reps (most of the time due to the specificity of their sport). Has there been any research to suggest that training with pauses has any significance on strength increase? Hope to here from ya!

[@JDEG100]

This is just a study that shows the same hypertrophy gains at different times. In any case, the fact that hypertrophy gains are similar is an advantage in favor of slow tempo reps. Since the possibilities of injury are reduced a lot, and that is already a reason important enough to use slow repetitions. I personally believe that the repetitions of slow time are superior in every sense, since they eliminate the moment and the inertia generated in the movement.

[@davidhandley1647]

@@JDEG100 good point on injury risk. I feel your right about longer times when bodybuilding. but in the case of training for sport maximum force production is a skill that one must develop through practice therefore giving merit to fast contractions. if you where to train with slow times and then try to express that strength in a sport using fast contractions you would find that you would generate far less power, also while attempting to express that strength with speed you would be at a greater risk of injury in those instances due to a lack of force production practice. therefore it is in that sense safer for athletes to use fast contractions in a controlled gym setting to prepare themselves for the demands of there sport. their is no one size fits all for any weightlifting parameter.

[@JDEG100]

@@davidhandley1647 With respect to the expression of power, there is not cientific evidence that show at a higher speed of movement better activation of the fast motor units. Actually what determines the type of motor unit used is the production of force required (ratio of force). We can activate and exhaust all the muscle fibers (slow, intermediate, fast) in an action where there is no movement, as long as the required force is high (isometric work). Maybe at a neural level we need a more specific adaptation to express the force quickly, anyway I dont think that translates to a specific skill required for a certain sport( better power and speed in a bench press or clean transferred in more velocity for a punch), I think in that case it is best practice a certain skill. Improving the strength of a muscle also improves the expression of power and speed, it's not necessary to do quick lifts to improve the speed of a specific sport skill, unless it is powerlifting or weightlifting. I hope you can understand me, it costs me quite the English language, but I understand your point.

[@davidhandley1647]

@@JDEG100 I agree with you completely. Well said

[@ferlou2373]

@@JDEG100you’re mostly right, except that you miss one crucial feature of the studies: they’re equated for volume which is absolutely essential for science since you want to be able to effects of volume from that of the different training modalities (like rep speed), but not realistic for practical purposes. Equated for volume, doing slower reps definitely is superior since you get equal hypertrophy with a slightly lower injury risk, but doing faster reps allows you to do more volume which is a huge benefit. People make similar mistakes when they read studies that correctly show that controlled for volume, a higher training frequency doesn’t lead to increased hypertrophy and conclude that there’s no point after all to increase training frequency as long as you keep the sets in a given session below 8-10 while missing that the main benefit of increasing training frequency is allowing greater volume.
