Circuit One: Push-Up and Rotate Reps: 10, alternating sides Begin in a plank position with your feet in line with your hips and your hands each holding a dumbbell. Lower your body toward the floor, then push through your arms, returning to plank. Twist to the left, reaching your left arm, dumbbell in hand, to the ceiling without letting your pelvis raise or lower. Return to plank position, bringing your hand back to the floor. This completes one rep. Do another push-up and twist to the right. Image Source: POPSUGAR Photography / Kyle Hartman
