This Dumbbell Circuit Workout Will Challenge Your Whole Body

• Lie on your back with your knees bent and your feet flat on the floor, hip-width apart. Hold a dumbbell in each hand by your chest.
• Squeeze your glutes to push your pelvis toward the ceiling, coming into a bridge. Keep your core engaged and ribs from flaring open; your body should form a straight line from shoulders to knees.
• Holding the bridge, press the weights to the ceiling directly above your shoulders, then lower them with control. Be sure to maintain a strong bridge position the entire time. That's one rep.
• Do 20 reps without lowering from the bridge.

Take a one-minute rest, and repeat circuit one. Then, rest for two minutes before moving on to circuit two.
