Supine Heel Slide Exercise
Learn how to do a supine heel slide to improve knee bending and mobility, with setup, dosage, key cues, common mistakes, and progression guidance.
How to Do the Exercise
Setup
Lie on your back with the working heel resting on the surface and the leg relaxed.
How to perform it
Slide the heel toward your hips to bend the knee while keeping the heel on the surface. Pause at a comfortable end range, then slowly slide the leg back out.
Dosage
2 sets, 8–10 repetitions, 2 seconds into bend, 5-second comfortable hold, 2 seconds out, Rest 30 seconds
What to Focus On
Key cues
- Keep the heel in contact with the surface
- Move to a comfortable end range rather than forcing the knee
- Keep the hip from rolling outward
Why use it
Restores active knee-flexion mobility and control through the available range.
When to use it
Useful when active knee bending is tolerated and you want to build comfortable motion without strap assistance.
Common mistakes
- Lifting the heel off the surface
- Forcing through sharp or escalating pain
- Rolling the hip outward to create more apparent knee bend
Know When to Progress or Scale Back
Use your movement quality and symptom response to decide whether the current version still fits.
Progress when
- The current range feels easier and controlled
- You can pause at end range without guarding
- Pain, swelling, and stiffness settle back toward baseline afterward
Scale back if
- Pain, swelling, or stiffness remains meaningfully worse afterward
- The movement becomes guarded or jerky
- You cannot keep the heel on the surface
Was This the Right Challenge Today?
Use the same three signals that matter inside Therapeutic Edge recovery plans: how challenging the exercise felt, how well you controlled it, and how your body responded afterward.
Answer after the exercise and, when possible, after you know your later or next-day response. This checks one exercise today; it does not change or save a rehab plan.
