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.
Lie face-up, knees bent, feet on ground. Interlace fingers, extend arms above your head and pull abs in.
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.
