Hip flexors run out
Weak hip flexors shorten the stride and slow the leg's recovery in sprinting. They are trained here too.

Trainer's Eye
Phase 5 opens on running mechanics — the hip flexors and hamstrings working fast, but still under control.
Weak hip flexors shorten the stride and slow the leg's recovery in sprinting. They are trained here too.
Lowering strength — downhill, decelerating, the last stride — is lost first and is where hamstrings fail.
How fast the load arrives matters as much as how big it is. That is why sprinting comes last.
Three couplets · two rounds · twelve minutes · hips that drive you
Knee up, toe up, heel up; step down under the hip — slow, exaggerated, tall.
Easier hands on hips · Harder faster
The same shape with a skip between: knee up, toe up, quiet elastic contact.
Easier march only · Harder higher and faster
Exaggerated long strides driving fully off each leg — count the bounds.
Easier normal running · Harder longer bounds
From a lunge, jump and swap the feet in the air, landing in the same depth.
Easier alternating lunges · Harder deeper
Bag held at the chest; drive the knee above hip height each step, tall throughout.
Easier bodyweight · Harder heavier
Knees nearly locked; paw the ground back under the hip on each stride.
Easier walking version · Harder faster
Each couplet: 60 s scored → the loading set → 10 s to move on. Done at 12:00.
