1. Single Arm Row
    For a single arm row, bend your left leg so it is at a 90-degree angle in front of you and stretch your right leg behind you, so your feet are about 2 to 3 feet apart. Lean forward at a 45-degree angle, place your left hand on your left thigh and extend your right arm (with a dumbbell in hand) down to the floor. Then raise the weight toward your chest with your elbow bent, in a rowing position. Lower it back down to the starting stance, and then repeat for 12-15 reps on this side. Then switch to the other side.
