Also the reason Usain Bolt leans to the right is scoliosis

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.

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.

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.

Lmao this manz speaking straight facts in the most simple words.

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.

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.

My man jumari is a smart man!

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.

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?

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

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

these reaction videos are it bro

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

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?

Does USADA have anything to do with this? Ijs

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.

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

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!

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?

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

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?

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?

Lime the video and content. With everything you said, one law of physics I have not heard anyone address.....gravity! More mass = more gravitational pull!

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.

Omanyala is listed as 180 5'9 ... doesn't look that to me, more like 5'6 or 7 and 190... fast stride frequency for sure

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

Wrong about harry aa - he’s been jacked since a young age at English schools He power cleans 150kg It’s his natural body type and been like that since young

Any good exercises for top end speed?

Im trying to get to 5'8 200lbs but I still find myself improving (im 185 rn) in the 100m and 200m

Micah williams you talking oregon

U think chinups rows, dips ohp, cleans is aight for Upper body

If someone is gaining muscle thrn they are gaining fat? What if they bodyfat level remains the same or even drops you can build muscle and lose fat at the same time.

Might as well just watch the original video. You added nothing.

Cristian coleman have just 5'6 of height? if this is true height isnt so important as i think for speed.

I think age is the only reason why he is slowing down

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?

1% bf is not 2 pounds. It is different for everyone.

Bro what % of 1RM increases relative power

Sprinters are asthetic not necessarily jacked.

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.

That’s a Scottish accent bro

can u stop comparing sprinters to body builders that train for asthetics
