Feet in Straps: Technique, Muscles Worked and Modifications
Feet in Straps, sometimes called legs in straps reformer, is a beginner to intermediate Pilates exercise performed on the reformer. The focus is on moving through leg circles, frogs, and leg openings while keeping your neutral spine held steady.
This movement pattern primarily targets the backs of your thighs and hips, specifically your hamstrings, hip adductors, and gluteus maximus. As you move the ropes, your transversus abdominis works as a supporting muscle to stabilize your torso.

How to do the Feet in Straps
Lie on your back on the reformer carriage with your head on the headrest and place the long loops securely over the arches of your feet.
- Start with your legs extended diagonally upward so the ropes are taut and your tailbone rests heavy on the carriage.
- Press your legs down toward the footbar by engaging the backs of your legs.
- Open your legs slightly wider than your hips to begin a circular motion.
- Circle your legs upward and around, bringing your heels back together at the starting diagonal.
- Bend your knees to bring your heels in toward your pelvis for the frog variation.
- Press your feet back out to the starting diagonal line.
- Keep your pelvis completely still throughout every variation.
- Breath. Instructors cue breathing differently, but you will often inhale as you bend or open your legs and exhale as you press the straps away.
- Where you feel it. You should feel the work in your hamstrings, inner thighs, and glutes, along with a steady effort in your deep abdominals. You should not feel pinching in your lower back or strain in your neck.
- How many. 5 to 8 slow repetitions for each variation
Common mistakes
- Tucking the pelvis. Keep your tailbone anchored to maintain a neutral spine rather than flattening your lower back into the carriage.
- Letting the straps go slack. Control the upward movement of your legs so the ropes keep a steady tension.
- Making circles too large. Limit your range of motion to a size where your torso does not rock side to side.
- Using momentum. Press and resist the straps slowly so your muscles do the work instead of the springs.
Make it easier or harder
Easier
- Use a lighter spring tension to reduce the resistance on your leg muscles.
- Keep your leg circles very small to help you maintain a steady neutral spine.
- Bend your knees slightly if tight hamstrings make it difficult to straighten your legs.
Harder
- Use a heavier spring tension to challenge your hamstrings and gluteus maximus.
- Lower your legs closer to the springs during the circles to challenge your transversus abdominis.
Who should be careful
- After the first trimester of pregnancy, many guidelines advise against long periods lying flat on the back. A side-lying or propped version is an alternative.
- Reformer springs and the moving carriage add load and instability. Learn it with a qualified instructor, who can set the springs for your body and goals.
