Elbow to Knee

A core exercise that targets the abdominals and obliques by bringing the elbow toward the opposite knee in a crunching motion.
Instructions
- Lie on your back on the floor with your knees bent and feet flat.
- Cross your right leg over your bent left knee.
- Place your hands gently behind your head, elbows out, with your shoulder blades starting on the ground.
- Flex your spine and rotate your torso to bring your left elbow toward your right knee.
- Squeeze your abdominals at the top of the movement.
- Return to the starting position in a controlled manner.
- Perform the desired number of repetitions, then switch sides.
Tips
- Keep your hands behind your head for support only, not to pull your neck.
- Focus on the rotation and crunch from your core, not neck strength.
- Move slowly and control the descent.
- Keep your lower back pressed to the floor throughout.
- This exercise can be performed without crossing legs for a standard crunch variation.
