The lying leg raise targets the abs by lifting straight legs.
Lie on your back, legs straight, hands under your buttocks or by your sides.
Raise your straight legs up to vertical, then lower slowly without touching the floor.
Your lower back stays pressed to the floor. If it arches off, bend your knees slightly.
