Exercise intensity refers to the level of exertion. For instance, lifting a weight that results in muscular fatigue after just a few repetitions or “reps” of an exercise is pretty high with respect to intensity. So too would be an all-out running or cycling sprint where fatigue occurs in a minute or so. Basically, the higher the intensity, the shorter the possible duration of the exercise. To reach such a high level of intensity, exercise often includes resistance against an otherwise simple movement of a muscle group or related groups. Examples of resistance training include weight training or running on an incline (for example, running on hills or a graded treadmill) or cycling (for example, cycling uphill or an exercisebike with variable resistance). It is the level of the resistance that dictates the level of intensity. Higher intensity and muscular fatigue will be associated with muscle adaptations that will allow for greater strength and power. In this case, muscles can enlarge or “hypertrophy.”

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.
