• Holding a dumbbell in each hand, hold the arms out wide with a slight bend in the elbows, palms facing up.
• Bend at the elbows, pulling the weights toward your ears.

• Stabilize your torso and keep your arms moving upward, performing an overhead press with your palms facing out.
• Lower your arms back to your side to complete one rep.

• Lean forward and bend both knees, remembering to keep a flat back.
• Extend your arms so they are straight. Lift the dumbbells straight up to chest level, squeezing your shoulder blades together as you do. Be sure to keep your elbows in and pointed upward. Don't arch your back.
• Slowly lower the weights back to the starting position to complete one rep.

Triceps Kickback

• Holding a dumbbell in each hand, hinge forward from your hips, bending the knees slightly. Bend your elbows behind you.
• Straighten your arms behind you with your palms facing in. Your arms should be parallel to the floor. Squeeze your triceps, and then return to the starting position.

• Start with the right side first. With control, keep your arm straight (but don't lock that elbow) and as you inhale, raise your right hand up toward the ceiling. You want your palm to be facing down and your arm to be parallel to the floor. Then as you exhale, slowly lower your hand back to your body. You should be able to see your hand in your peripheral vision. Your arm won't be directly out to the side but slightly forward.
• Do the same move with your left arm.
• Then do both your right and left arms at the same time to complete the rep.

• With control, return to the starting position and repeat on the other side. This completes one rep.

Plank Dumbbell Row

• Start in a plank position with your legs wider than hip-width distance; the wider stance makes you more stable. Hold onto your dumbbells, keeping your wrist locked to protect the joint.
• With your core tight and your glutes engaged, exhale, stabilizing your torso as you lift your right elbow to row; feel your right scapula sliding toward your spine as you bend your elbow up toward the ceiling.
• Keeping your neck long and energized, return the weight to the ground to complete the rep.
