Crunch
Crunches are a classic core-strengthening move. The act of lifting your upper body works your abdominal muscles.
- Start on your back. Bend your knees and plant your feet on the floor at hip width. Line up your head and spine. Cross your arms across your chest.
- Tighten your core and relax your neck and shoulders. Tuck in your chin and lift your upper back, keeping your lower back, pelvis, and feet on the floor. Pause.
- Slowly lower your upper back to return to the starting position.
- Start with 1 set of 8 to 12 reps.
