Key Benefits

  • Builds eccentric strength and tendon capacity
  • Improves control through the lowering phase
  • Great bridge from pain-limited work to heavier strength
  • Easy to progress with load and range
Slow lowering is the point—treat each rep like a controlled “negative.”

How to Perform

  1. Start on a step with both feet and rise up onto your toes.

  3. Lower slowly on the working leg until you reach the bottom range you can tolerate.
  4. Put the other foot back down to help you rise again.

  • 2–4 sets of 6–12 slow eccentrics per side
  • 3–5 seconds lowering each rep
  • Progress by adding load every 1–2 weeks as tolerated

When to Use It

Calf/Achilles strengthening, tendon resilience work, and return-to-running prep when you need better lowering control and tolerance.

Frequently Asked Questions

Should this be painful?

Mild discomfort can happen with tendon loading, but sharp or worsening pain is a sign to reduce range, load, or volume.

Do I have to go below the step?

Not at first. Use a smaller range and build toward deeper range as tolerance improves.

How do I make it harder?

Slow the lowering more, add a backpack, or increase range gradually—only if you can keep the rep smooth and controlled.
