Alternating Single-Leg Arm Bent-Knee Sit-Up Under

Starting Position

Lie flat on your back on a yoga mat with your legs fully extended and your arms overhead, resting on the floor.

Execution

1. Core Engagement: Simultaneously lift your torso and one leg off the mat by contracting your core muscles.

2. Movement: Bring your torso upright while bringing your knee toward your chest. Keep your upper body engaged.

3. Flexion: Briefly hold the position at the top, ensuring your balance is centered on your tailbone.

4. Return: Slowly return to the starting, fully extended supine position in a controlled motion.

5. Alternation: Repeat the movement with the opposite leg, alternating for the duration of the set.

Maintain a smooth, continuous tempo and avoid using momentum to swing your body up.
