In this study (miller et al., 2021), researchers found that elite sprinters had larger hip extensors than sub-elite sprinters.
Glute max size alone explained 43.8% of sprint performance differences, while total hip extensor volume explained 47.5%.
It’s an interesting finding,

but correlation ≠ causation. Athletes predisposed to be fast may also be built this way, and a lot more goes into sprint performance than muscle volume alone.
Still, the hip extensors are critical, powerful hip extension drives both acceleration and max velocity.

Sprinting itself is the best way to develop these muscles. Strength and hypertrophy work can support sprinting, but they don’t replace it. Keep the focus where it matters…getting faster on the track or field.

sprints, rest intervals, strength methods, programming throughout the year, tempo runs, plyos, resisted runs, it’s all broken down inside Speed Kills, my flagship program.
Some of my older programs are also on sale right now as well.
