Lat Pulldown

The pulldown exercise is a strength training exercise designed to develop the latissimus dorsi muscle. … The cable lat pulldown is done where the handle is moved via a cable pulley, as opposed to doing pulldowns on a leverage machine.
The lat pulldown is a compound exercise, meaning it works several joints at once — and thus, several muscles. While the latissimus dorsi is the primary muscle worked, the biceps and muscles of the forearm act as helpers. Several of the muscles of the rotator cuff also assist as you pull the bar down.

Leg Extension

The leg extension is a resistance weight training exercise that targets the quadriceps muscle in the legs. The exercise is done using a machine called the Leg Extension Machine. … The exercise consists of bending the leg at the knee and extending the legs, then lowering them back to the original position.
The leg extension is an isolation exercise that targets your quadriceps, the muscles on the front of your thigh. It is a simple movement, which occurs at only one joint — your knees. The leg extension strengthens your quadriceps. and if done correctly, is not hard on the knee joint.

Preacher Curl

Sit down on the Preacher Curl Machine and select the weight. Place the back of your upper arms (your triceps) on the preacher pad provided and grab the handles using an underhand grip (palms facing up). Tip: Make sure that when you place the arms on the pad you keep the elbows in.
Since the long head of the biceps makes up the mass of the biceps peak, the incline curl is an effective exercise for building the biceps peak. When you perform the preacher curl, your arms move in front of your body. … Therefore, the short head of the biceps takes the majority of the load during the preacher curl.

Pec Deck Fly

A machine fly, alternatively called a seated lever fly or “Pec Dec” fly is a strength training exercise based on the free weight chest fly. As with the chest fly, the hand and arm move through an arc while the elbow is kept at a constant angle.
While primarily working the pectoralis major muscles, using a pec fly machine requires some support from the pectoralis minor muscles in the chest, the deltoid muscles in the shoulders, and the serratus muscles in the rib cage.

Hamstring Curl

The leg curl, also known as the hamstring curl, is an isolation exercise that targets the hamstring muscles. The exercise involves flexing the lower leg against resistance towards the buttocks. Other exercises that can be used to strengthen the hamstrings are the glute-ham raise and the deadlift.
A quick explanation: The leg-curl machine targets your hamstrings because it requires you to flex your knees—one of the jobs of your hamstrings—against a resistance. … So as leg curls go, it’s a far better choice than the machine version. But here’s the best part: It’s also a great core exercise.
