All sprinters need a certain base level of strength, or torque.
It’s also easy to tell if you have enough, or are lacking.
Check out your angles at the start.
Are you deep (chest low to the ground) on take off?
Are you deep AND straight body lines?
If you are, you’re strong enough.
If you’re not, you need more strength.
You would also need things other than Squats
such as
Mediball squat dives
roll back and dive
Hops and dive
Plyro’s
Dude - Your legs are huge - you don’t need much in the way of Squats - a few heavy sets, low reps. Keep it very simple - or your legs will blow up too big.
