Ready to add a challenging move to your regular strength-training routine? You need this Warrior 3 variation in your life. This move works your glutes and core and tightens up the backs of your upper arms while testing your balance.

• Stand on your left foot, and lean forward while lifting your right leg until your leg and torso are parallel with the floor. Squeeze your right glute and bring the weights to your ribs with your elbows pointing toward the ceiling.
• Keep your abs engaged as you exhale, straightening your elbows. Your arms will be a few inches above your back.
• Inhale and bend your elbows, bringing the dumbbells back to your ribs to complete one rep.
• Do 10 reps, then switch legs.
