Reverse Leg Crossover
The Reverse Leg Crossover is a rotational core exercise that targets the obliques and increases spinal mobility by moving the legs side-to-side from a stable back position. By maintaining a tabletop leg position, it strengthens the midsection while improving lower back flexibility.
Iridium schedules this rotational movement by analyzing your 7-day workout history to ensure your obliques and hip flexors aren't already fatigued from recent heavy compound bracing. Since this is a bodyweight exercise, the AI monitors your RPE and rep performance to detect when you need to increase volume to maintain progressive overload fitting your specified training methodology.
Form Cues
- Extend arms out to the sides with palms down to anchor your upper body
- Bend knees to 90 degrees and stack them directly over hips
- Contract your core to press your lower back into the floor
- Lower your legs slowly to the side while keeping opposite shoulder pinned down
- Exhale forcefully to pull your legs back to the center using your obliques
- Don't allow your shoulders to lift off the ground during the rotation
- Don't let gravity take over; avoid dropping the legs quickly
- Don't arch your lower back when returning to the starting position
- Don't swing your legs using momentum instead of muscle control
Common Mistakes
- Lifting the opposite shoulder
- Using momentum to swing legs
- Failing to control the descent
- Arching the lower back excessively
Muscles Worked
This exercise primarily targets the internal and external obliques, which control the rotation of the torso and stabilize the spine. Secondarily, it engages the lower abdominals (rectus abdominis) and hip flexors to maintain the legs in the elevated tabletop position against gravity.
