Single-Leg Calf Iso Hold

How to do it

Stand on one leg on a step edge, ball of your foot on the step, heel hanging off. Use a wall or rail for balance. Rise as high as you can onto your toes and hold the top position — squeeze hard, breathe steadily, and stay centered over your foot.

Why it's good for runners

Holding the top position builds calf endurance and tendon resilience without aggravating sore tendons. It's one of the most useful exercises for runners dealing with Achilles tendon pain or plantar fasciitis, and it strengthens the calf-and-Achilles chain that absorbs every running impact.

Common mistakes

Don't let yourself sink during the hold. If you're slipping down before the time is up, end the set — a shorter hold at full height beats a longer one that slowly collapses.
