Accentuate the Positive
Trying to achieve killer abs? Us too, but according to Peterson, it's more than just doing sit-up after sit-up. Maintaining curves like Vergara's is a balancing act, it's not all about the mid-section. Peterson says, "We work on shoulders to accentuate her small waistline. We do some isolation work but mostly compound (movements that require more than one joint, and more than one muscle group) as it's more efficient."
