Tight, Toned, and Strong: A Lower-Body Circuit With Weights

Get ready to feel this in your upper back — it's great for your posture, too.

• Holding your dumbbells, bend forward at the hips keeping your back flat and your knees slightly bent.
• 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 and return to the standing to complete one rep.
• Do 12 reps.
