6 Ronnie Coleman

Two big reasons why Coleman will be trying for Sandow number nine on September 30 are his left and right pectorals. Throughout his reign atop the bodybuilding world, few challengers have been able to hang when he puffs up his pecs during side shots or when he induces a flurry of ridges by crunching out most-musculars.

Coleman goes as heavy as possible for 10-12 reps per set, and he built his chest primarily with barbell and dumbbell presses.
