Ankle Mobility

Rigid ankles will result in feet slapping the ground. A mobile ankle results in a "press and push".
Two exercises from Elite Performance and one from me - try these BEFORE you run:
-Eccentric Calf Raises (heel drops): 2x 10 reps per side. Push up with two feet, lower down with one.
-Isometric Lunge and Lift: 3x 5 reps per side with a lift btwn each set of 5.
(Bonus work for quads, hips, and core)
-Anterior Ankle Mobility: 2x 5 reps per side, hold forward for 2-3 seconds per rep.
