after 30 years of working with elite sprinters and throwers my observations are the same as Ash and Tom … progressive fundamentals (except in the case of specific identified injury/joint limitations etc) work best
Shotputters do better adddressing basics in the gym such as incline press (200kg common) squat (300kg) and power snatch (130 -150kg) than any single limb exercise …. single limb gets worked well in throwing drills (heavy and light shots)
In my humble opinion the ant tib is also a bit of a red herring … anything that improves flexion-extension strength and range throuhg the ankle joint helps sprinting action but again on the track is the place … in the gym heavy basic fundamentals
but I am an old man fixed in my ways perhaps >>>
cheers and best for training successes
