Ah, the dreaded crunches. They’re not very much fun, but they’re necessary if you want great abs. Some gyms offer crunch machines, so you can try those if you’d like. Or, if you prefer, you can use a decline bench. Either way, remember to crunch with your tummy, not with your head or neck. Aim for 3 sets of 12.
