In CFTS page 42 Charlie states the ff. on calisthenics: “A sprinter must have full control of his body and should handle his bodyweight easily”.
On page 3 Charlie states that: “most sprinters are unmade due to inappropriate training… the conversion of white fast twitch fiber into red endurance fiber”.
My question is: Will high rep bodyweight squats be ok to include in a sprinting program? Or will this cause the leg muscles to transition into red fibers?
