Lie on your back, extending your legs and joining your feet. Tighten your core, pressing your lower back into the mat, then lift your legs and head slightly, reaching your arms toward the ceiling. Keep your lower back in contact with the floor throughout the movement.
Slightly arch your lower back to deepen abdominal engagement. Control any swaying to maintain stability. Keep your shoulder blades firmly planted on the mat. Focus on core activation, not lifting as high as possible.
