Soleus Stretch

Bending the back knee takes the gastrocnemius out of play and shifts the stretch to the soleus, the deeper calf muscle that drives ankle push-off. This bent-knee version improves ankle dorsiflexion, which carries over to squatting depth and running mechanics. Pair it with the straight-knee calf stretch for full coverage.

How to do it

  1. 1

    Stand facing a wall with your hands on it and step one foot back a short distance.

  2. 2

    Keep the back heel down and both feet pointing forward.

  3. 3

    Bend the back knee toward the wall while keeping the heel planted.

  4. 4

    Sink down until you feel a stretch low in the back of the calf, near the Achilles.

  5. 5

    Hold for 30 seconds, then switch legs.

Tips

  • Use a shorter stance than the straight-knee calf stretch so the heel stays down.
  • Drive the knee forward over the toes to bias the deep calf.
  • If the heel lifts, shorten the stance until it stays flat.

Variations

Common mistakes

  • The front leg carries the weight while the back knee bends in the air with nothing on it, so nothing pushes the back ankle into any new range.
  • The hips drop into a squat with both knees bending together, which lowers you toward the floor without moving the back ankle any further.
  • If the stretch shows up high in the calf, the back knee is not bent enough to take the gastrocnemius out of the way; bend it more and the sensation slides down toward the Achilles.
  • The back knee drifts inward as it travels forward, so the arch collapses and the ankle finds range by rolling in rather than by bending.
  • Thick, stiff running shoes soak up most of the ankle movement; do this barefoot or in something flat so the joint actually reaches the end of its range.

Frequently asked

How long should you hold the soleus stretch?
Three rounds of 20 to 30 seconds per leg beats one long hold, since the ankle gives ground in small increments. If you are chasing squat depth or dealing with stiff ankles from running, do it before you train as well as after, and check progress with a knee-to-wall test every couple of weeks rather than by how it feels.
How do I make the soleus stretch easier or harder?
To make it easier, stand closer to the wall so the back foot has less distance to cover and the heel stays down without effort. To make it harder, put the ball of the back foot on a book or a low wedge with the heel still on the floor, or take the same position half-kneeling with your hands down and your weight over the ankle.
What is the soleus stretch good for?
The bent knee puts the work on the soleus, so this is the version that improves ankle dorsiflexion for squat depth, lunges and running push-off. It is the wrong pick when the tightness sits high in the calf belly, where the straight-knee wall stretch reaches further. If the Achilles is painful rather than stiff, stretching it harder is not the answer; ease off and have it assessed.
