Leg Extension & Curl Machines Buyers Guide

On this list of the best leg extension and curl machines, there are seven excellent choices, each one has a different thing it excels at. Knowing what a particular machine is good at allows you to choose one based on what it is the best at doing, however, what other things should you be looking for when you are ready to purchase one of these machines? Here we will examine more about these machines and explore what to look for to ensure you get the right one for your specific situation.

Leg Extension VS Leg Curl- Differences, Similarities, Pros & Cons

Both popular exercises are important to do if you want to make sure your leg muscles are toned and strong, but what makes them different? Which one is better?

Leg Extension Definition

Leg extensions are strength training exercises. They work on strengthening your quadriceps. Leg extensions are typically done while you are sitting down, the leg will lift a weight, putting pressure and resistance on the quadriceps muscles.

Leg Curl Definition

Leg curls are exercises that you can do while laying on your stomach usually. Weights are placed on the back of the ankle or lower calf area, to add resistance. The leg is bent at the knee bringing the ankle toward the buttocks. Leg curls are also called hamstring curls and they will strengthen the hamstrings with repeated workouts.


Leg extensions work your quadriceps which are the large muscles in the front of your legs. These muscles are used heavily during sports like cycling and kicking. Many MMA fighters and professional football and soccer players have leg extensions in their daily routine and report significant improvement in their leg strength.

Leg curls work your hamstrings which are the muscles in the back of your legs. They are done on a padded machine. The hamstrings are engaged to bend your knee. The knees must be bent over and over while running, walking, or swimming. Swimmers and professional marathon runners like to use leg curls to strengthen their hamstrings and improve their strength while swimming or running.

In summary, leg curls and leg extensions isolate different muscle groups. Leg extensions focus on the quadriceps while leg extensions work the hamstrings.


Both exercises are necessary if you want to have strong and healthy leg muscles. If you avoid leg extensions, you may end up with weak quads and if you don’t do enough leg curls your hamstrings may not be strong enough.

They are both performed best on a special machine, like the ones featured here on this list. Professional athletes use both exercises to improve their lower body strength and endurance.

Leg Extension Pros

  • Easy to do on the right machine
  • Strengthen your quadriceps
  • Rewarding to see your muscles increase in size
  • Having strong quads makes the entire body stronger

Leg Extension Cons

  • Causes stress on the knee joint
  • Increased use of rectus femoris joint
  • Can harm your knee if too much weight is used
  • Can cause leg fatigue fast

Leg Curl Pros

  • Strengthen the hamstrings and calf muscles
  • Simple exercise
  • Does not hurt your knees
  • Improve mobility
  • Make your calf muscles bigger
  • Improve flexibility in the legs

Leg Curl Cons

  • Can cause fatigue in the calf muscles
  • Can be harmful to your back if done incorrectly
  • Some people say leg curls are a waste of time
  • Some say you can get the same results from less stressful exercise like running

Types of Leg Extension & Curl Machines

Leg extension and curl machines come in a couple of different types. Many are part of an all-in-one home gym setup, while some are designed specifically for these exercises.

All in One Machines

Some of these machines are add-ons with multipurpose home gyms. These are the most common type since there are so many brands and styles of home gyms available. You can find many different leg workout options on almost all the most popular home gyms.

These all-in-one type machines are great if you need a machine that will provide leg workouts as well as full-body workouts. However, these all-in-one machines may not be necessary if you are solely focused on leg workouts. If you fall into this category, a specialized machine is going to be a better option for you.

Specialized Machines

Specialized machines are designed to do one or two very specific jobs. This type of leg workout machine is best for fitness enthusiasts who already have a full-body machine or are not interested in doing full-body workouts.

Usually, specialized machines will be better at their job, due to being designed to fit only one or two special needs. When a machine is designed to do everything, the functionality of each job tends to be only adequate, seldom excellent. For this reason, I tend to recommend specialized machines to people who are beginners or people that are serious about focusing on their legs primarily.

What to Look for In a Leg Curl Machine


No exercise equipment is going to help you if it is not good at its job. While researching which machine to get, it is important to consider how well it is going to do the job. You can usually discern if it is good at its job by reading the customer reviews and looking at the design. In the case of leg workout machines like extension or curl machines, the key factors to look at are the design of the hinged area and the pads used to protect your legs.

Ask yourself some of these questions while determining if a machine does its job well:

  • Is the leg curl section of the machine free of extra things that may block it from moving (additional sections or unnecessary add-ons)?
  • Are the pads soft enough to make using it comfortable and enjoyable?


This may or not be relevant to your situation. If you need to have access to multiple exercises on one machine, versatility is going to need to be a factor in your purchase decision. It is a nice benefit to have a leg exercise machine attached to an upper-body workout bench, for sure. However, having a versatile workout machine usually comes with a larger size, heavier weight, more complicated setup, and a higher price tag. If you need an all-around home gym and not just a leg workout machine, consider how versatile the machine is when you are making your decision on which to buy.

If you need only a leg workout bench or machine, versatility does not need to be part of your purchase decision.

Ease of Use

Nobody likes difficult to use gear. Some exercise equipment can be complex to use and hard to set up. The more it can do, usually the harder it is going to be to assemble and use.

While you are looking at different machines, ask yourself these questions to help determine the ease of use:

  • How many pieces does it come with?
  • How many moving parts are involved to do the exercise I am interested in?
  • Do I need to do any special setup to prepare for leg curls or can I just do them any time?
  • How long will it take to assemble the machine?
  • How many steps are involved in preparing the machine for leg extensions?

After asking those questions, you should start to get a good idea of how easy it is to set up and use any of these quality machines on the list. All of them are reasonably easy to use or they would not be included here, but some are easier than others!


Longevity is usually mentioned in the same sentence as quality. They are kind of the same thing. If something is well made, it will last longer, which is what longevity is. This attribute is closely tied with the price since you are probably willing to spend a little more on something if it is made to last longer and cause less stress.

If you are a budget shopper primarily focused on price, you are not going to be very interested in how long a machine will last. However, if you are willing to spend more on something that will last longer, you can consider the following things to determine the quality of the machine, and therefore the longevity:

  • Does it have a warranty?
  • Is it steel construction?
  • If it is steel construction, how many layers does it have? (measured in gauges like 5 gauge, 7 gauge, etc. higher gauge is thicker steel)
  • Does it have a scratch-resistant coating?
  • Do the pads have moisture-resistant coatings to fight exposure to salty sweat?

Size & design

Everyone has space constraints and specific requirements. Most of these machines are close to the same size and take up a similar amount of space on the floor. However, they are not all the exact same, and in the case of floor space, the details matter.

Ask yourself a few questions when considering size and design?

  • What are the measurements of the machine? (72 inches equal six feet / 36 inches equal 3 feet)
  • How much space do I have in the room where I plan to put the machine?
  • Is this machine tall? Will it be close to the ceiling?
  • Will the design work with where the door is in my room?

Determining if it will work in your space is critical since these can take some time to assemble, you do not want to buy one that will not fit and waste your time.


How much it costs is always part of the purchase decision-making process. Price alone should not be the reason you decide to buy or not buy a leg workout machine. Consider what features and benefits you will get for the price you are paying.

Value is important to consider as well as price, they are closely linked. If something seems expensive, ask yourself what you are getting for that money? Is it worth the extra money to get this benefit?

Oftentimes, a cheap price will get you a poorly made or badly designed product. In the case of these leg curl and leg extension machines featured here, they are all high-quality machines worth purchasing, however, you still need to figure out which benefits, and features are important and what you are willing to pay for them. When it comes to fitness equipment, I try to avoid the cheapest option because they are mostly not good products. On this list, every product is good, but how much are you willing to spend?

Who Should Buy a Leg Extension and Curl Machine?

A machine like this would benefit anyone who is trying to improve their overall health, but it will especially be useful for fitness enthusiasts who are focusing on their lower body strength and muscle health.

Why Buy a Machine if You can Just Run?

Of course, the argument can be made that you can get plenty of leg exercise by running or cycling or swimming, and buying an expensive machine is not necessary and is just a waste of money.

While this argument is partially true, it is not telling the whole story. Running, cycling, and swimming are incredible activities that I highly recommend everyone do. The more you run or cycle or swim, the more toned and flexible, and healthy your legs are going to be, this is not something that is debatable.


However, leg curls and leg extensions give you targeted, specialized workouts that laser focus on specific muscle groups in a way that those other activities simply can not do. When you work your legs on a leg curl machine, you are focusing hard on your quadriceps. Doing reps with a reasonable amount of weight will focus the quads and add muscle mass and tone to those muscles.

Running engages your quads significantly, but only for the time that it takes for your foot to strike the ground and your knee to begin bending forward. There is no doubt that doing leg curls will give your quads a targeted workout that is an excellent supplement to the activities you are already doing like cycling, swimming, or running.

Hamstrings & Calves

Leg extensions are especially good at working your hamstrings and calves. These muscles are also engaged when running, cycling, or swimming. The big difference with a leg extension machine vs those other activities is that when doing leg extensions, you are adding a measured amount of resistance to the movement and doing it repetitively. This adds layers to your calf muscles and hamstrings.

In addition to adding muscle mass to your calves and hamstring muscles, doing leg extensions also trains your muscles and helps your flexibility and mobility. While it is true that you increase your flexibility and mobility by swimming and cycling, when you add leg extensions on a machine you are increasing the benefits you gain from the other activities.

The truth is that to have a strong and flexible lower body, you should run, cycle, and swim as well as work out on a leg machine like the ones featured here. These machines are also especially useful for pro athletes who need to optimize the specific muscle groups these machines target, the calves, quads, and hamstrings, and to a lesser extent, the lower back.
