How to do it

Setup

  • Set the sled safeties
  • Place the forefeet securely on the plate
  • Bend the knees and hold that angle
  • Keep the back and pelvis supported

Execution

  • Lower the heels while knees stay bent
  • Press through the forefeet to plantarflex
  • Pause at the top
  • Return to the same heel depth

Common Errors

  • Straightening the knees
  • Moving the entire sled with the legs
  • Bouncing at the bottom
  • Letting feet slide

Cues That Work

  • Freeze the knees; heels move; press through the forefoot

No-Fly Zone

Avoid loads that straighten the knees or turn the movement into a partial leg press.

Programming

Sequence priority

Late

Direct soleus work is low in systemic fatigue and should follow compound lower-body work that needs stable ankles and legs.

Progression

Model — Double

Fallback model — Density

Mark the knee angle and foot position; add reps before load and reject any progression that straightens the knees.

Best program fit

Legs

Load increments

Standardone small matched plate per side
Smaller incrementadd reps or a bottom pause
Larger incrementthe next matched plate increase after knee angle stays fixed

If it hurts

Pain is information, not a challenge to push through. Stop the set if pain is sharp, worsening, or changes how you move. These are exercise-selection options, not medical diagnosis or rehabilitation advice.

Work down this list in order. Stop at the first change that removes the pain.

  1. Step 1

    Setup tweaks

    Reduce load, increase foot security, or use a smaller controlled heel range.

  2. Step 2

    ROM / tempo / bias

    Add a two-second bottom pause and a slow return.

  3. Step 3

    Implement swap

    Seated calf-raise machine or bent-knee dumbbell calf raise.

Substitutions

Approved fallback

Seated calf-raise machine or bent-knee dumbbell calf raise.

The Evidence

Bent-knee plantarflexion changes calf-muscle contribution, but exact emphasis depends on knee angle, machine setup, and individual anatomy.
