With basic movements, never fall below 8-10 reps. You want major muscle groups to work hard and grow. The actual amount of weight used is always secondary. Concentrate on getting a the right contraction and burn. The pump is what’s important. So pay attention: strict form is extremely important.
Biceps: Close EZ Bar Curls
This movement is similar to the barbell curl except you use a special EZ bar. Use a close grip here and again, make sure you squeeze the bicep throughout the curling movement and avoid using momentum to swing the bar up.
Chest: Flat Dumbbell Flyes
Lie on a flat bench and grab two dumbbells. Your palms should be facing inward. From the starting position at the top, slowly lower the weights following a semi-circular motion until the dumbbells are out to your sides. Be sure to keep your elbows slightly bent to take pressure off them.
Legs: Squats
While in the squat rack, place the bar on your back just above the traps, step back and set your feet about shoulder width or maybe a little wider, toes pointed forward, keep your head up and then squat the weight down till your thighs are parallel to the floor, make sure your back is flat and never relax your back while squatting, push the weight back up to the start position.
Back: Dumbbell Rows
This movement is similar to a bent-over barbell row except you use dumbbells. Begin by placing your left leg on a bench, keeping your knee straight, and your left arm on the bench, with your arm straight. Grab a dumbbell in your right hand, with your palm facing inwards. Holding the weight in your hand, slowly bring it up to your rib cage area. Bring the weight back down to the starting position and repeat.
Calves: Standing Calf Raises
Place feet close together, on the ball of your foot (the part just behind the big toe) on the toe plate of the calf raise machine, keep knees locked and then raise the weight using just your calf not your butt or your knees, come up all the way and then back down all the way to stretch the calf. Do not relax the muscle at any time. always keep tension on the calf even when stretching.
Tricep Pressdowns
Standing in front of cable machine elbows tight at your sides. Slowly push the weight down and extend arms, squeezing the tricep then back up to start position.
Shoulders: Bent-Over Laterals
Bending over at the waste, knees slightly bent, grab 2 dumbbells. While in this position lift the weight out and up and don't swing the weight up using momentum.
