10. Leg raises
Don’t flatten your lower back against the surface – maintain its natural curve. Your goal is 3 sets, each set including 10 reps with a 30-second rest.
1. Lie on your back, arms by your sides and legs extended, feet slightly off the floor.
2. Slowly raise your legs perpendicular to the floor and hold at the top for a second.
3. Return to starting position to complete one rep.
