sprinets flexible

Does men liek asafa powell and bolt are flexible?
do streches gives more power, because now i even cant touch my feet with my hands.
how streched i should be? and how to become flexible?
Your opinnions?

and why asafa powell 1.93m height is 85 kg?

but usain bolt 1.99m only 75 kg?

and one more question.
does back bottom has any influence in running?

I wouldn’t pay to much attention to what athletes are listed at weight wise on the internet.

Flexibility can help with power application throughout the full range of motion as well reducing the injury risk. That said, Linford said to me he could never touch his toes.

In terms of the butt muscles, Darren Campbell once described them to me as his engine! So that gives you an indication of their level of importance.

Charlie, what is your opionion on correspodence between static flexiblity and sprinting?

powell 188 86 88 kg
bolt 195-6…86 kg from last 2 yeaars…I suppose low 90…got definitely bigger…
Flexibility…specific flex to get correct angle, but don’t expect lots of splits from 100m athletes

Id think a sprinter should be generally flexible where they can touch their toes and have good range of motion. This would be enough for them to have proper range of motion through each stride and not get injured/recover quicker.

well i read that asafa id 193 and bolt 199
