The cable standing leg curl is a single-leg isolation exercise for the hamstrings, the muscles along the back of the thigh. Using an ankle strap attached to a low cable pulley, you curl your heel toward your glutes one leg at a time, giving the back of the thigh constant tension through the full range of motion.

How to do the Cable Standing Leg Curl

  1. 1Set the cable pulley to the lowest position and fasten the ankle strap snugly around one ankle.
  2. 2Face the machine and grip the frame or a stable support for balance, standing tall with a slight bend in your supporting knee.
  3. 3Brace your core and keep your hips square and stationary, with the working thigh roughly aligned with your standing leg.
  4. 4Curl the strapped heel up toward your glute by bending the knee, keeping your upper leg still and squeezing the back of the thigh.
  5. 5Pause briefly at the top once your hamstring is fully contracted.
  6. 6Lower your foot under control back to the start, resisting the cable rather than letting it snap your leg down.
  7. 7Complete all reps on one leg, then switch the strap to the other ankle and repeat.

Form tips

  • Move only at the knee — keep your thigh and hips fixed so the hamstring does the work instead of your hip swinging the leg.
  • Control the lowering phase; resisting the cable on the way down is where much of the muscle tension is built.
  • Hold the support lightly for balance rather than leaning on it, so your standing leg and core stay engaged.
  • Use a full range of motion on every rep, from a straight knee to a full squeeze, rather than short partial curls.

Common mistakes

  • Swinging the whole leg from the hip instead of bending at the knee, which shifts work off the hamstring and reduces the effect.
  • Letting the cable yank the leg back down quickly, which wastes the resisted lowering phase and can strain the knee.
  • Arching the lower back or rocking the torso to fling the weight up, cheating the rep and risking the lower back.
  • Loading too much weight so balance breaks down and form collapses before the hamstring is properly worked.

Frequently asked questions

What muscles does the cable standing leg curl work?

It isolates the hamstrings — the muscles along the back of your thigh that bend the knee. Curling the heel toward the glute keeps tension on the back of the thigh throughout the movement.

Is the cable standing leg curl good for beginners?

Yes. It works one leg at a time with light, controlled loads, so it's an accessible way to learn to feel and isolate the hamstrings while you hold a support for balance.

How many sets and reps should I do?

For most lifters, 3 to 4 sets of 10 to 15 reps per leg works well. Since it's an isolation move, slightly higher reps with controlled tempo tend to feel best.

What's a good alternative to the cable standing leg curl?

Lying or seated machine leg curls train the same hamstrings with both legs and heavier loads. The standing cable version is useful for single-leg focus and constant cable tension.

Where should I feel the cable standing leg curl?

You should feel it in the back of your working thigh as you curl the heel up. If you feel it mostly in your hip or lower back, you're likely swinging the leg instead of bending purely at the knee.
