My next favorite strength exercise is the fly. It’s not as popular, perhaps, as the bench press or as practical as the row, but it feels good.
We all need that feeling of expansion in our chests that we get in the lowering phase of the fly.
Additionally, when we do flies, we have to concentrate. Form is important. We need to pay attention to how far we can lower the weights and still get them back up. We need to know how to protect ourselves if the weight becomes too heavy (Bend your elbows, bring the weights in toward your body, and then, if necessary, drop them on the floor. You are more important than the floor. And ripped rotator cuffs are No Fun.)
Another great thing about flies is that when we do them, we learn about the value of the eccentric contraction. Eccentric, in this context, doesn’t mean slightly odd. When we lift weights, the working muscles contract; this is the concentric phase. Then when we lower them again, the muscles lengthen; this is the eccentric phase. Because the eccentric phase cooperates with gravity, the job our muscles are doing in this part is controlling the descent. When we do flies, that lowering phase requires control because if gravity takes over, we are back to that ripped rotator cuff scenario. (Choose your weights wisely and it’s good to have a spotter.)
Go play.
