Build Tree-Trunk Legs

Blast your lower body the smart way: The straight-leg deadlift works your hamstrings harder than the leg curl machine does, suggests a University of Memphis study. “The exercise activated the most muscle in the lowering phase,” says lead study author Brian Schilling, PhD. Do 3 sets of 10, taking 4 seconds to lower the weight.

Dumbbell Straight-Leg Deadlift

Stand with a dumbbell in each hand, letting them hang in front of you. Keeping your knees slightly bent and back straight, push your hips back to lower the weights slowly to your shins. Pause. Push your hips forward and rise up.
