25. Dumbbell Skull Crushers: The exercise name says it all, so be sure to follow closely: Lie face up on a bench with feet planted on the floor and your back pressed down. With a dumbbell in each hand, raise the arms straight up (palms facing each other). Then, bending only at the elbows, lower the weight down to your ears, finishing in 90-degree angle. Return to starting position.
26. Renegade rows: James Dean probably did these in his sleep. Assume the push-up position with feet about shoulder-width apart and dumbbells placed in each hand, positioned below the chest. Next, pull the right dumbbell toward the oblique muscles, keeping it close to the torso. Lower the dumbbell back down and repeat on your left side. Continue for reps on each side in an alternating fashion.
