The long arm crunch is one of the most effective ab exercises; changing the traditional floor crunch by straightening the arms behind you. The long-arm crunch adds a longer lever to the move that adds a bit more challenge and difficulty.
Targeted Muscles: rectus abdominis, external obliques and internal obliques.
Step 1:
Lie face-up, knees bent, feet on ground. Interlace fingers, extend arms above your head and pull abs in.
Step 2:
Lift arms, head and shoulder blades off the ground at the same time, exhaling in 2 counts. Slowly lower in 2 counts and repeat.
Reps: 12 2 counts
Trainer’s Tip: Keep arms aligned with ears, shoulders relaxed, as you lift and lower.
