1
Lie flat on your back on a mat or floor with legs extended and arms positioned at your sides or across your chest. Keep your neck neutral and shoulders relaxed.
2
Engage your core by drawing your navel toward your spine. Position your legs in a 90-90 position (hips and knees bent at 90 degrees) or keep them extended based on difficulty preference.
3
Slowly lower one leg toward the floor by extending the hip, allowing the opposite leg to remain in the bent position or extended. Control the descent to maintain lower back contact with the floor. Feel the abdominal muscles lengthen as the leg lowers.
4
Press through your core and return the lowered leg to the starting position by flexing the hip and engaging the abdominals. Alternate legs in a controlled, alternating pattern or perform all reps on one side before switching.
