Prisoner One Leg Twist
Prisoner one leg twist is a bodyweight balance and core exercise targeting the obliques. Combining a single-leg stance with rotational trunk movements challenges balance, spinal rotation, and lateral core strength.
How to do it
- Stand on one leg with your hands clasped behind your head in a prisoner position.
- Slowly rotate your torso to the right, bringing your right elbow back.
- Hold the rotated position for 2 seconds, then rotate to the left.
- Continue alternating twists while maintaining your balance on one leg.
- Complete the desired repetitions before switching the standing leg.
Form cues
- Keep your chest tall and shoulders relaxed.
- Fix your gaze on a stable spot on the floor to maintain balance.
- Rotate strictly from your upper body, keeping your hips stable.
- Move slowly and control every inch of the twist.
Breathing: Inhale as you return to the center, and exhale smoothly as you rotate to the side.
Common mistakes
- Rushing the rotation, which compromises balance and reduces muscle engagement.
- Swinging the hips with the twist, which takes the work away from your obliques.
- Slouching forward, which strains the lower back and collapses your posture.
Muscles worked
Primary: obliques. Secondary: abs, lower back, quads.

What should I do if I keep losing my balance?
It is completely normal to wobble when starting. Focus your eyes on a non-moving point on the floor a few feet ahead of you, and lightly touch your raised foot down if you need to reset.
Am I supposed to feel this in my lower back?
You should feel this primarily in your waist and obliques. If your lower back starts to ache, reduce your range of motion and focus on keeping your core gently braced.
How often can I practice this exercise?
You can include this exercise 2 to 3 times a week as part of your core or home workout routine.
