HIP FLEXORS

Eccentric lunge

1. Step forward with your left leg and lower into a lunge over 3-5 secs, activating the hip flexors of your right leg.

At the end of your range, push your right foot into the ground and hold for a few secs (maintain the contraction in your hip flexors), or do six mini lunges before returning to standing. ‘ Be sure your pelvis is facing forward, as it would be in the correct running position,’ says Blazevich. Repeat on the other side. Do 3-5 reps per leg.
