This is the last of these posts on non-running stuff I do. This one is more strengthening than flexibility.
First, a prone plank (as in photo below). There's no need to do this for more than 2 minutes. Keeping your back straight, alternately lift one leg at a time, doing 20 kicks per side.
Next, supine plank leg lifts. 15x each leg. If you have Haglund's, these will hurt at first.
