Get in a 20-minute lunchbreak workout with these moves.
Hold a dumbbell in right hand, arms at sides with palms facing in. Bend at hips as you step out to the left in a wide lateral lunge. As you lunge, bring right arm across your body, touching the weight to the floor in front of left toe. (You can rest left arm on your waist.) Push off from left foot to return to start. Switch the weight to left hand, lunge to the right side, and bring the weight down to right toe. Continue alternating sides for 12 to 18 repetitions.
