Incline Dumbbell Bench Press
Lie on your back on an incline bench set between 15 and 30 degrees, and hold a pair of dumbbells above your shoulders with your arms straight. Lower the dumbbells to the sides of your chest. Pause, and then push them back up. Do 10 reps and rest for 20 seconds. Decrease the weight of the dumbbells by 20 to 30 percent and perform 10 more reps.
Elevated Plyometric Pushup
Assume a pushup position with your hands on a bench. (The higher the bench, the easier the exercise.) Your body should form a straight line from ankles to head. Bend your elbows and lower your body until your chest nearly touches the bench. Then push up with enough force so your hands leave the bench. Land with your hands on the bench and repeat. Do 5 to 10 reps.
Pullup
Hang at arm's length from a chinup bar using an overhand grip that's slightly beyond shoulder width. Squeeze your shoulder blades together and pull your chest to the bar. Pause, and then return to the starting position. Do 5 to 10 reps.
Towel-Grip Inverted Row
Secure a bar in a power rack at about waist height. Drape two towels over the middle of the bar so they're slightly beyond shoulder width. Grab the ends and hang from them with your knees bent, your feet flat on the floor, and your body straight from knees to head. Pull your chest toward the bar. Pause, and then slowly return to the starting position. Do 10 reps.
Supported Single-Arm Dumbbell Row
Hold a dumbbell in your right hand, place your left hand on a bench in front of you, and assume a staggered stance, left foot forward. Hold your elbow in as you row the wight to the side of your torso. Do 10 reps, switch arms and leg positions, and repeat the movement.
Dumbbell Triceps Kickback
Grab a pair of dumbbells, bend your knees and lean forward so your torso is nearly parallel to the floor. Tuck your upper arms next to your sides, bend your elbows, and hold your forearms about parallel to the floor, palms facing up. Simultaneously extend your arms straight back and rotate the weight so your palms end up facing each other. Return to the starting position. Do 15 reps.
Dumbbell Hammer Curl and Press
Standing with your feet shoulder-width apart, hold a pair of dumbbells at arm's length by your sides, palms facing each other. Without moving your upper arms, curl the weights to your shoulders, and then press them overhead until your arms are straight. Reverse the move to return to the starting position. Do 10 reps.

Muscle Mass Prevents Sarcopenia
In 2005 the Mediterranean Intensive Oxidant Study determined there was a direct link between skeletal muscle mass, bone density and mineral content while studying osteoporosis in men. Force exerted on the skeletal system in proportion to the strength and thickness of the surrounding muscles through exercise and normal activities produces stronger and denser bones. A man with a full reserve of muscle mass will enjoy stronger bone, greater strength and ample dexterity.
Muscle mass or the lack thereof has also been linked to common diseases such as cardiovascular disease and diabetes. The results of a study published in Circulation, a scientific periodical, in 2006 connect sarcopenia to insulin resistance, elevated lipid levels in the blood, and increased body fat, especially visceral adipose tissue.
Research also concluded that long-term adaptation to resistance training lowers cortical response to acute stress; increases total energy expenditure; relieves anxiety, depression, and insomnia; and demonstrates beneficial effects on bone density, arthritis, hypertension, lipid profiles, and exercise tolerance in coronary artery disease subjects. The good news is that these studies are in the infinitesimal stages and, it is believed, with more research will come more evidence of the relationship between muscle mass and disease states.
A study conducted about a decade ago at East Tennessee State University revealed some interesting facts about cardiovascular exercise and its lack to contribution to the development of muscle mass. Forty-three healthy subjects 55 and older were studied. Twenty-three of the individuals did only aerobic activities, treadmill, bike and elliptical, for 30 minutes 3 times per week for 4 months. The remaining 20 individuals split their time doing 15 minutes of aerobic activity and the remaining time lifting weights using machines. There was a significant increase in bone density and muscle mass in the split-routine group while the aerobic group showed no gains in muscle mass or bone density.
The prescription for muscle mass enhancement and the accompanying benefits according to Wolfe, Kraemer, Chodzko-Zajko, and other experts is to work at or above 70 percent of your maximum perceived effort. This produces cellular and metabolic changes that forge stronger, thicker muscles and associated health benefits. The principle of strength training is to progressively overload the muscle(s) and allow for recovery.
When muscles are worked to the point of momentary failure microscopic tears are produced in the myofibrils, the contractile units of the muscle cells. The body reacts to these tears by sending protein cells to the site of the damage to bond with the muscle increasing strength.
To complete this miraculous process you must feed your body properly for recovery. Protein produces the building blocks for the body. Professor Wolfe contends in his study, "The Underappreciated Role of Muscle in Health and Disease," that we need 0.8 to 1 gram of protein per pound.
