The Foot Exercise That Unlocks More Power Cal Dietz

September 16, 2026 Off By FitnessTips

Most athletes spend a ton of time strengthening their hips, knees, and legs—but the only thing actually touching the ground is your feet.

In this video, Cal Dietz shows me the Spring Ankle Exercise, a simple isometric drill designed to strengthen the foot and ankle in positions that carry over to sprinting, jumping, and athletic movement. We go through the low and high positions, how to progress it with load, and why weak feet can become the limiting factor once the rest of your body gets stronger.

I’ve dealt with foot issues over the years, and this is exactly the kind of exercise I like: simple, effective, and easy to work into your training.
