Bench presses work your chest, shoulders and triceps and are done with a barbell. Lie face-up on the bench with your knees bent and feet flat on the floor. Once into this position, grasp the bar with a wide grip, push it off the supports and hold it directly above you. Slowly lower the bar down to your chest, push back up and repeat for 10 to 12 repetitions.
Bent-over rows work your back and arms, and are performed with dumbbells. Stand with your feet shoulder-width apart while holding the weights in front of your thighs with your palms facing you. Slowly bend forward until your back is slightly higher than parallel to the floor and let the dumbbells hang straight down. In a steady motion, pull the weights up to your stomach and squeeze your shoulder blades together. Lower the dumbbells back down and repeat for 10 to 12 repetitions.
Military presses work your shoulders and are done on a workout chair with a pair of dumbbells. Sit on the chair with your back against the backrest, the dumbbells held right above your shoulders and your palms facing forward. In a steady, arcing motion, push the weights above your head and toward each other until they are an inch apart. Slowly lower them to the starting point and repeat 10 to 12 times.
Tricep dips work the muscles on the backs of your upper arms. This is a common area for loose skin. To do dips, place two benches parallel to each other and slightly wider apart than the length of your legs. After grasping the edge of one bench with your hands shoulder-width apart, place your heels on the other bench. Your arms should be extended at this point and your butt should be just in front of the bench. Slowly lower yourself down by bending your elbows. Once your upper arms are parallel to the floor, push back up and repeat 10 to 12 times.
Stationary lunges work your glutes, quads and hamstrings (the muscles of your butt and thighs). Stand in a staggered position while holding dumbbells at your sides. Slowly lower yourself down by bending your knees. Once your front knee parallels the floor and your back knee is an inch above the floor, come back up and repeat. After you have done 10 to 12 reps, switch sides.
Twist curls work your biceps using dumbbells. Stand with your feet shoulder-width apart while holding the weights at your sides with your palms facing in. In a steady motion, lift the dumbbells and twist your wrists so your palms are facing your chest. When you do this, squeeze your biceps forcefully, lower the weights back down and repeat for 10 to 12 repetitions.
