What to Look for in a Leg Extension Machine

Now, it's your turn to do your own research to determine which of these products would be the best fit for your personal workout space.


The first thing you should do is measure the size of the space you plan to commit to your leg extension machine so you know it will fit properly. You don't want to have to move equipment around because you need the space to use the machine or make the extra room and compromise something else. Once you have this information on hand, find the machine that would fit in your allocated space.


Next, you need to choose the machine that will support the weight you plan to use. If you have standard plates, then a machine that only supports Olympic plates won't work. However, Olympic plates will fit on one-inch sleeves. If you choose to use a machine with a weight stack, make sure it has enough to suit your needs.

Don't just think about the weight you can use now, think about your future self and choose a machine that will support the weight you feel you can use in the future. If a stack goes up to 200 pounds, but you can work with 300, then it won't serve you as well as a machine that could support that kind of weight will.


The frame of the machine should be solid enough to support you and the weight you're using while the machine is being used. A leg extension machine with a steel frame would be best, and the adjusting parts should be high-quality, as well.

The padding of the machine also matters. Thin padding with low-quality covering will suffer damage quickly, and that is an extra cost and issue you would have to deal with. Thicker padding with quality vinyl covering is worth the cost in the long run.

Buckle Type

Some leg extension machines have buckles that can help you stay secured to the machine while your legs are working. The strap for the buckle should be strong and fit tightly once the buckle is secured. The buckle itself should be easy to secure when you get into place and simple to remove once you're finished.

If the machine doubles as a seated leg curl, then the thigh pad should provide a snug fit to help you stay in place, as well. If the pad comes loose during the set, then the machine can be damaged and you could suffer an injury as a result.

Benefits of Leg Extension Machines

The leg extension machine can help you isolate the quadriceps when training. This exercise can help you prepare your knees for more intense leg work to come later in a workout. You can work each leg individually or both at the same time.

The leg extension exercise can add variety to your leg workouts, as well. It can be performed at any portion of the workout. Doing it at the start of the workout can help pre-exhaust the quads, or you can do it at the end of the session as a finisher or burnout exercise. There would be no need to perform single reps with a super-heavy weight, but you can use moderate to heavy weight for muscle growth.

FAQs About Leg Extension Machines

Are leg extension machines worth it?

Leg extension machines can add value to your home gym and training experience. Having a leg extension machine would offer an exercise that can help you improve the shape and development of your thighs, which can translate into improved performance in other athletic endeavors such as running, jumping, and other dynamic activities.

Can you build big legs with the leg extension?

The leg extension can help you build bigger and stronger quadriceps, specifically, but they don't do as much for the hamstrings and glutes. To build overall bigger legs, you should also consider focusing on other exercises such as squats, deadlifts, leg curls, and lunges.

How many times a week should I do leg extensions?

You can perform leg extensions once or twice a week as part of a full leg routine to improve the size, strength, and shape of your quadriceps. They can be performed as a warm-up exercise for your knees or as a supplemental exercise for a larger leg routine.
