thanks i didn’t know

ohh thats why. I didnt make that connection

and he still is the fastest ever. thats crazy

It’s like a videogame when building your character. You can big and strong but you won’t be as fast. Or you can have less strength but be faster and have more agility.

[@justjumari]

spitting lowkey !

[@Leonidas-eu9bb]

sprinters are generally more torso dominant. A proximal weight distribution. I also totally agree that focusing too much on muscle mass is not good for sprinting. Most top atheltes have good muscle building genetics. especially black sprinters.

@@justjumari bro what’s your 100m best, always been curious?

[@bui340]

He's talking about skeleton build when comparing shoulders to hips. And how that impacts where you're fast in the 100 m. It's an interesting view.

[@energyzer_bunny1913]

It's pretty crazy because I feel like I'm at the point in my career where I don't really need to lift like I did in my early 20s. Now that I'm in my late 20s, I shifted to doing more resisted sprinting, weighted jumps, resisted plyos, throws, and the occasional light Olympic lift. Pool work has also been a huge plus. I feel once you've been in the weight room for 3 to 4 years, it'll give you diminishing returns on the track. Long story short, I shifted to doing more light power training and plyos and less strength training. I believe you have to shift your training as you age in this sport.

[@fastcheetomonster4879]

I used to be all about the mindset lifting heavy weights will make you faster and thats all it is. though im like way younger than you 😅. But this year ive found why that doesnt work and Jamari helped me see that. But yea I agree with everything you said

[@justjumari]

i see that

[@tquasa07]

[@happyfacendlovu5673]

True what u saying in this video. Put it this way: Sprinters are like an F1 Racing Car: comparatively smaller, but very powerful. All about science, physics, relativity and perception.

[@kaiphanstudenthbhs2582]

One thing I noticed about Aikines is that his upper body is much bigger than the size of his lower body. His lower body looks similar to Bolt's. Do you think he is still fast because he did not gain weight in his lower body?

[@fastcheetomonster4879]

Jamari what do you think about olympic lifts. I saw in another video that you would rather do other things instead, but im just curious.

[@johanneseiksund6930]

i appreciate it , not my best one but i’ll come back

Are increases in relative strength and power achieved through plyometrics and overcoming isometrics?

[@herolddujour5961]

Justjumari, I am new to this sprinting stuff and to your channel (just a few months) I am currently training with weights (secondary training), like I'm doing weighted knee drive (10 lbs) standing for hip flexors, heavy pull ups for upper body (40 lbs 6-5 reps), weighted push ups, and weighted lunges and jump squat. Any feedback?

[@justjumari]

eh it’s pretty meh, go to my justsprint pro website and do the free workout from phase 1 day 1

[@crazylongjumper5252]

hi bro ı have the one question for you Can you make a video about how fred kerley can run so fast? please

[@justjumari]

one day

[@janithdealwis8805]

For the case of Harry Aikines, I have seen many of his videos where he does a lot of plyometrics. It is a bit hard to say he lacks power to weight ratio, Cz I have seen his vertical jumps. He definitely has 40+ inch vertical. Do you think he is lacking mainly horizontal power?

[@flightreacts4603]

I don't think so , i think there is video that he broad jump over 11ft

[@justjumari]

yea your definitely right i didn’t explain it well. but it’s a hard case for sure, horizontal power is one huge case, the actual like scientific term is horizontal impulse , and looking back at is he is probably missing out on alot of top end speed, which is your ability to resisted deceleration in the last 30-40m. with all the mass on his body i could see that being a huge issue

[@flightreacts4603]

@@justjumari probably his elastic power relative to his weight is not that great compared to sprinters running sub 10, so he is lacking top end speed

[@maunerlacayo4944]

Maybe he lack of enough mobility in his shoulders and hips

We want to look buff when running in a tank top... Carl Lewis said sprinting is done from the arms down! 💪🏋

[@BrainInjurySurvival]

Does USADA have anything to do with this? Ijs

[@justjumari]

i will say in this video i was chatting a bit and was off a lot of caffeine so idk if i got my point across correctly. i do believe athletes within first 1-3 years of training can see great benefits from muscle and strength gains, just we are seeing time and time again with new training that velocity based work is producing the best results, and a lot of those athletes are very slim. once you hit a certain strength to bodyweight ratio you will start to get negative feedback from pushing strength too far, and that’s where i believe people like harry aikines is falling into currently. sorry!

[@leonsmith3030]

that's literally me too. I jumped way higher when I was only repping 255 explosively. As I pushed to see what my max are, the weights go slower and I noticed that I am not as fluid with my jumps.

[@justinjumariburner]

@Abdul Sabit Ariff oh oops totally forgot to do that my bad thanks

[@jasonliu8217]

Hi im a HS runner/jumper. Everytime I ask about weighteded workouts ( gym) I get very diverse opinions. But currently, Im doing pushups, pullups, dips, and abs everyday with out any weights. What is your opinion on training in the gym and what are some workouts I can do? Thank you

[@leroy5272]

just sprint pro answers that for you 🤷‍♂🤷‍♂

[@justjumari]

a good place to start is bodyweight of course but you need very foundational movements one squat, one hinge, one horizontal push, one vertical push, one horiztonal pull, one vertical pull. do 3x6-10 for all of these e exercises to start off. if you don’t now what those mean, you can google them and it’ll make sense then just fill in what i said

I think the smaller you are the amounts of speed you can produce good example is su bingtan he is 5'8 and has faster feet and he is lean he has little to no body fat.

I have a slim upper body but big calves is this slowing me down my upper body frame is the size of a 14 year old but I'm 15 and my lower is big because I focus on my quadriceps muscles by doing jump squats and other plyometrics is this slowing me down?

[@waterflesh2153]

No, this video is talking about weight after reaching a certain speed or plateau.

[@spartangaming5078]

Any good exercises for top end speed?

[@justjumari]

flying sprints and anything ankle dominate

Yohan is not big he weighs like 170 and 5 feet 11. So i agree with you

[@spencerphillips2658]

With Harry AA, even though he does a lot of weight training, doesn't he have a myostatin deficiency to where he can't help but be jacked?

[@justjumari]

that’s an interesting take i’ll look into

[@joseyuyarimilianmartinelli750]

idk depends on your definition of jacked. To me, asafa, yohan blake are ABSOLUTELY jacked. Bodybuilder is just another level. And that other guy i wouldnt call a twig. But yes its true that even though there are some kinda big guys like yohan, there are a lot of slim sprinters, who look like they dont lift at all sometimes, and they are fast fast fast.

Can you cover speed & jumping in football? ⚽️ (“soccer”)

it’s not much different from any other sport i cover. you need good acceleration , max velocity, and a very reactive and strong ankle to get off one foot well

Ankle stability aside what helps most with acceleration… exercise wise? To train in season.

200 lbs is probably too much. Even Asafa Powell, who is 6’2”, is 192 lbs. If you want to prioritize your 100m and 200m, you shouldn’t gain weight. But if you want to gain muscle and bulk, then go for it!

Yo at 12:44 you mention 90% of these sprinters are on steroids. So what, does that mean nobody can make it to elite level without juicing?

lol if you read my pin comment i was CHATTING. its a possibility but all steroids do for sprinters is help with the amount of sprint training you can do, not really in output sk yes it’s very possible to succeed without juicing . it’s probably not that likely pro guys juice. i work with a 10.2 guy and he doesn’t he just worked hard and he had bad genetics

A lot of the stuff you’re saying is very wrong. But correct enough to build a decently fast sprinter. That’s why you’re a good 10.2 and 20.4 coach. But that’s why you’re not a sub 10/20 coach or sprinter. Keep digging and you’ll find the truth.
