For horizontal projection at start, it’s more about projecting your hip forward, and then your knee and torso angles will be natural. If you focus on torso and knee angles, you are mimicking the angles, instead of getting to it in a athletic natural state

Great video. The forgotten man of sprinting, Maurice Greene, was an absolute master at staying low and transitioning into top speed whilst staying relaxed.

im a simple man athlete x posts i listen i like

since some viewers might not have a standard track or a pair of spikes, I'd like to point out that it's impossible to reach optimal angles to aply horizontal force on slippy grounds. Grass without spikes, coal track without spikes are good example of this: it's impossible to reach optimal horizontal force, so "training" aceleration on these might even be deceiving

This YT channel is gold for sprinters

I love the evidence based position. Thank you..,been meaning to add sled runs in

Excellent video Cody, many thanks. Just to pick one thing, I liked your tip about how sometimes it's easier to keep the torso angled down if the head is in a more neutral position

bro this video came out at the right time I'm so bad at accelerating I need to get better at it

Seriously enjoyed this video Cody, you're an absolute boss at deciphering the literature! Thanks a million 💪🤝

Thanks athletes X

Super informative! Thank you a lot, Cody!

Great explanation!💪🏿

As always! Thanks for the content Cody!

Your videos are very helpful

Thank You 🙏🏼 ❤🎉

What if i combine those with elevated split squats and heavy sleds would that make the progress better and faster?

Thanks so much, Cody. What about using a parachute instead of a sled? Is there a difference?

I feel going too low wouldn't effect the time you have to re orient your limbs because when that happens you catch yourself. That "catching" is when your hip flexors drive your leg far enough ahead to create enough vertical force. So if you could get your legs that far ahead, you have enough time get it at the proper position. Going too low means you don't enough vertical force and so if you continued like that, you would fall.

Your upper core and your lower core must be strengthen in order to hold angles.

It's about magnitude and not direction. However it's about the magnitude of HORIZONTAL force (which is direction, but it's the net result and we must look at the magnitude of horizontal force you know), and for that people need to get to a low angle. Legs should be at a low angle, because they are what produces force, but since every part of our body is attached to other parts, to get legs to a low angle, people need to get the whole body to that angle. Basically it's about putting the center of mass in that position and everything else will follow it. There are guys who sprint at more vertical angles and they may accelerate faster only because they produce more force in general and that necessary horizontal part of the whole force production is bigger than somebody else's. Tho if that guy could get to a lower angle, he would run faster because he would get more force that is required to accelerace horizontally (this is exactly what's happeninig in sprinting, people gain horizontal acceleration til they hit top speed) As for the fact that sprinters show higher horizontal forces at top speed. Force changes how bodies move, it accelerates or deccelerates them in certain directions. If no force is applied, an object is gonna move in the same manner (either moving somewhere or staying at the same spot). At top speed sprinters can't accelerate to a higher velocity (it's their limit as we've established). No acceleration means no force is required. However there is some braking force when sprinters put their legs in front of their center of mass (so they don't apply 100% vertically, when the leg is in front, some of that force is oriented horizontally), and also some air resistance. But in the latter part of ground contact phase, the center of mass goes in front of the leg and this results in the leg not applying force 100% vertically again. Some of that force is gonna be oriented horizontally and that's gonna be propelling force (so now there's an equilibrium and that's how one maintains top speed). But notice, this is not pure horizontal force. It's just vertical force at an agnle. So I guess the correlation they've fould is misleading becasue it's just more vertical force,that faster sprinters have, resulting in more horizontal force when vertical force is applied at an angle. This can be further backed up by the fact that horizontal force is only needed to keep going and not accelerate the body at top speed.

Great video. Needed this. If my sprint drives are a little slow and my strides are 8 steps to 10m, would this help fix that. Also when driving out the blocks should the aim be slow and powerful or quick quick quick.

Can a hill replace a sled or is a sled the better choice..........thank you

Is there a way to learn low heal recovery during drive phase? I keep cycling my legs during that phase

Whaty about running up the hill? Will it achieve the same affect?

Thanks for this video! I have trouble with my shin angle being almost vertical during the start. Any thoughts on how different types of resisted sprints can be used for acceleration? I'm wondering if I should invest in a sled (and studded/cleated shoes if on grass) or just use hill sprints.

Great video and a great flag ! 🇺🇸

So maintain a bent knee during the start?

So in blocks should you still look a little upwards or just keep your head down looking at the ground ?

Yeah what about hill sprints?

Sir, the issue I'm facing is my relative lower body size and strength (sp. posterior chain) is much higher than the upper body, my legs turn at 5 Hz. Vertical without using arms is 28" but using arms is only 35". The upper body can't keep up with the lower body force and turnover speed while sprinting. May you please provide the fix to this issue? I would be glad to hear that from you.

20% of their weight is ideal weight for the sled? Is that what you're saying? Thanks

should I wear spikes when i do sleds?

How would you calculate the weight that would give 20% reduction in sprint time? 20% of bw?

So essentially, optimize trunk flexion while maintaining proper hip alignment?

Can I use a tire as a sled, planning to attach a rope with a tire and putting the rope around my waist and sprint with it

Respectful sir My feet go sideways what i do plz comment sir

Hi man from Italy, i appriace this video. I bought your 8 weeks off season 100m training program, and i'm in Fourth week now, my ask is: 2 times track workouts at week only now? then you increase track workout? Thanks man i love your training program!

👏🏾👏🏾

How do I increase my broad jump?

Hey Cody what is your 100 m time with no disrespect I’m just curious because you look speedy bruh 😂

i saw U

The real question is how fast can you run?🤔

You’re born with it or without it
