Bob Greene Reveals the Ways You're Sabotaging Your Workouts

Bob often sees people lingering over super-slow biceps curls and then complaining that they don't have time to work other parts of their arms. "Biceps are one of the least functional muscles for real life," he says, pointing out that we rely more on our triceps for putting boxes on shelves, pushing up out of an office chair or reaching into the back seat of a car. He recommends mixing popular biceps exercises with moves that work the triceps, shoulders and back.
