Opposite Leg Toe Touch
The Opposite Leg Toe Touch is a dynamic core exercise that targets the obliques and upper abdominals through a cross-body crunching motion. This bodyweight movement improves core stability, coordination, and hamstring flexibility by alternating reaches toward opposite feet.
Since this exercise relies heavily on hip flexor stamina and abdominal endurance, our AI analyzes your RPE and rep performance to determine if you are truly fatiguing the core or just swinging your limbs using momentum. If your HealthKit data indicates low back strain or poor sleep recovery, the AI can instantly swap this for a more stable regression like a Dead Bug to protect your spine. Over time, the system learns your flexibility limits and adjusts volume to ensure progressive overload without compromising movement quality.
Form Cues
- Press your lower back firmly into the floor before starting
- Exhale sharply as you lift and reach across your body
- Lift your shoulder blade completely off the ground
- Keep your legs as straight as possible to engage the core fully
- Control the descent slowly rather than dropping back down
- Don't use momentum to swing your upper body up
- Don't let your lower back arch off the floor
- Don't strain your neck by pulling with your head
- Don't rush the lowering phase of the movement
Common Mistakes
- Arching the lower back
- Pulling on the neck
- Using momentum to swing up
- Bending knees excessively
- Rushing the negative phase
Muscles Worked
This exercise primarily targets the obliques and rectus abdominis by combining spinal flexion with rotation, creating a comprehensive core stimulus. It also engages the hip flexors to lift the legs and requires stabilization from the transverse abdominis, making it excellent for functional core strength.
