Lunge Curls

For glutes, hamstrings, quads, biceps

Holding a 5- to 8-pound dumbbell in each hand, stand with feet together and arms at sides. Step forward with left foot and lower right knee toward floor (don't let left knee go beyond your ankle). At the same time, curl weights toward shoulders. Return to starting position and repeat with right foot. Do 20 reps per leg.
