Criteria Used for Evaluation
A non-adjustable leg curl machine would probably cause joint injuries and back pain.
Adjustable points in leg curl machines include the backrest, bench, ankle pads, weight capacities, and range of motion via sundial constructions with a pin. On some machines, you can also use a large pin to convert from a leg curl to a leg extension machine so you can work out your entire lower body.
This is a large array of options, and not every leg curl machine will have every adjustment feature. Many times, you will have to compromise with a lower priced model that still has features you need. We have tried to highlight all the different adjustable options for each machine we reviewed. You can make a decision based on which features you will need, rather than paying extra for features you may never use.
You need a leg curl machine that can keep up with you as you grow stronger.
A machine that is not durably constructed will leave you disappointed quickly, as you have to take advantage of the manufacturer warranty or fend for yourself if there is no warranty.
There are certain features to look for when it comes to how durable a machine will be. Double stitching in the padding is a plus. Another thing to look for is the quality of the vinyl covering. Also, more moving parts can mean more chances for the machine to break down. The finish of the machine is a good indicator. The best leg curl machines will be powder coated, perhaps even electrostatically powder coated, to help prevent scratches and other superficial damage.
Even the way the machine sits on the floor will help you determine how durable it is. A wide base with some sort of leveling or gripping mechanism shows the care the manufacturer took in making the product. Also, look for a product that offers optional rubber flooring. Or you can look for rubber flooring from a different maker. Either way, the extra layer of rubber will both protect your floor and keep the legs or feet of the machine from excess wear and tear.
You need support whether you are sitting, standing, or lying prone.
Support takes many forms when discussing or reviewing leg curl machines.
Your body weight has to be supported. The bench accomplishes this, both in prone and seated positions. Some machines will have back support, while others will not. Obviously, if you have lower or upper back pain, you will want back support. The best machines have adjustable back support, too, so you can dial in the exact amount of help you need.
Ankle rollers may seem basic, but they ensure you get a full range of motion without putting too much stress or weight on your ankles. So the ankle rollers are part of a leg curl machine's support system. You can go for extra padded rollers if you need to. Always make sure the rollers are covered in vinyl or another strong material, and that padding is present.
A heavier machine will provide optimal support, but it will also cost more and will be difficult to move. In selecting a leg curl machine, always look for the tradeoff between price and support. Make sure you are not setting yourself up for injury later by trying to save money and get a bargain with your initial purchase. Bargains and value prices are great, but they should not be the only consideration.
The features of a leg curl machine help determine performance, effectiveness, and longevity.
Leg curls machines may not have as many features as, for example, an exercise bike. There are typically no cup holders, media shelves, or Bluetooth capabilities. Still, there are certain features and perks you can look out for. Selecting a machine with the right features may keep you from having to spend money on an upgrade later.
How does the weight load? Do you need spring clip collars, or can the weight just sit on the bar with no danger of falling off? These are questions you can ask yourself. You may also want to look at whether you can switch from one-inch weight plates to 2-inch Olympic plates, and how easily you can do this should you choose.
If the machine converts from a leg curl to a leg extension machine, how does it do that? Do you get a good V-shaped bench when you lie prone? Sizes and qualities of pins and moving joints can vary from manufacturer to manufacturer.
The sundial backrest adjustment is another feature that not every leg curl machine has. Some users find the sundial mechanism easy and convenient. If you have never used one, you will want to try out a machine at the gym or a fitness outlet to see if the sundial adjustment is right for you.
Motion control prevents injury and ultimately gives you a more effective workout.
Motion control refers to a consistent movement when you do each rep of an exercise set. It also determines whether you can get a full range of movement. Carefully designed motion control features, too, will prevent you from hyperextending your leg and getting an injury that could sideline you for a while.
Motion control, in leg curl machines, is often a function of bearing type, pivot points, ankle roller adjustability, and backrest adjustability. The overall quality of the machine will make a difference as well. As with any piece of fitness equipment, look for a reputable brand that stands by its products and offers warranties. If you are buying used, come prepared with questions for the seller and do your research on the machine before making any purchase.
Expert Interviews & Opinions
Even the simplest pieces of fitness equipment can cause pain and sprains when used improperly. A leg machine is fairly simple, but it still has moving parts and things to look out for if you want to keep yourself safe and get the most out of your workouts.
Adjust the back pad so that your knees line up perfectly with the pivot point. The pivot point is located at the end of the seat. This is probably the primary consideration when it comes to leg machine safety, as misaligned knees will cause joint pain quickly and will sabotage your results.
Make sure the ankle support is on your ankles, touching the tops of your shoes. The ankle support should never be on your shins, as this will restrict your range of movement and also distribute the weight unevenly.
When you get to the top of the motion, when your leg muscles are contracted all the way without being hyperextended, hold the curl for a few seconds. This helps ensure that your leg muscles are doing the work of lifting, and you are not relying on momentum. Letting momentum do the work will shortchange you and take away from the effectiveness of your workout.
Leg curls and leg extensions are similar, and even work out similar muscle groups. But there are some important differences to keep in mind as you move from one exercise to the other.
The leg curl machine will target your hamstrings. These are the muscles running down the backs of your legs. The hamstrings are responsible for bending your knees. Strong hamstrings will help you with running and other outdoor activities.
The leg curl will also work out your calves, specifically the gastrocnemius muscle. This muscle goes over the back of your knee and helps the hamstrings do their work. Leg extensions will also help strengthen your gastrocnemius muscles.
The leg extensions will target your quadriceps more than any other muscle group. The quads are a large muscle group responsible for movement and flexion over most of the front part of your legs. Working the quadriceps is important, as these muscles support you when you stand and have a big responsibility when you walk or run.
Other Factors to Consider
There are not many accessories that can go with a leg curl machine. But the ones that are available are important and can be a key part of your level of satisfaction with your purchase.
Rubber protective flooring is one accessory to think about. It will protect your floor from scratches and other damage, while also making the leg curl machine more stable.
Weight plate adapters are another feature. Some machines come with the sleeves you will need to convert from standard weight plates to Olympic plates, which have a bigger orifice for the bar to go through. However, unless you are competing, lifting significant amounts of weight, or changing and moving your weight plates often, you may not even need Olympic plates. Olympic plates are easier to move and load on the machine because they have rubberized grips.
Another accessory to think about is one that does not go with a leg curl machine at all. XMark and other manufacturers offer an extension that can mount on any weight bench and give it leg extension and curl capability. This may be a good option for you if space is at a premium in your home gym. However, you will not get a backrest or many other features unless the weight bench came with them.
Capacity refers to how much weight your leg curl machine can handle.
This is an important feature if you are training to lift a lot of weight, or looking to become a serious weightlifter. You do not want to be limited by a machine that maxes out at 200 or 250 pounds. This may mean paying more money for a reinforced machine that will let you safely load up the weight plates to gain mass and strength.
On the other hand, if you are more of a fitness lifter or using the leg curl machine as cross-training for sports like soccer, you may be fine with a 200-pound machine. The capacity you select will depend on your goals with the machine and how much weight you think you will need to lift as an upper limit.
Frequently Asked Questions
q: How will stronger hamstrings help me?
Stronger hamstrings will help you in nearly every area of your life. If you run, walk, or hike often, or if you run indoors on a treadmill, the hamstring muscles will keep you standing and moving longer. You can hike, run, and walk faster and farther if your hamstrings are conditioned.
The hamstring muscles will also help you in daily life, as they are a functional muscle group. Doing chores, lifting groceries or children, yard work, and anything involving twisting, turning, or stooping motions will put your hamstrings to work. Lifting an appropriate amount of weight at the leg curl machine will make all these motions safer and less painful.
q: Are leg curl machines safe?
Leg curl machines are very safe if used according to manufacturers guidelines. The most important consideration is to align your knees with the pivot point. You should check this every time you get on the machine. Misalignment will restrict your range of motion and can cause joint and knee pain over time.
You should also properly position your ankles on the ankle roller. The best padding and covering cannot prevent an injury if you are placing the roller near your knees instead of directly on the ankle.
q: What is a sundial adjustment?
A sundial adjustment is simply a plate with holes cut in it at carefully spaced intervals. The plate is shaped more like an oval than a circle. By taking a pin out of the plate and moving the backrest up and down, you can move the pin to different holes all the way up or down the sundial. When you get close to a hole, the pin will pop into place. This is how you select the backrest angle that gives you the most comfort and the best results. A sundial is more convenient, and faster than a system where you have to take a pin out and move it by hand.
q: How much weight can I lift with a leg curl machine?
If you train slowly and take rest days, you can lift as much weight as you like. However, the more weight you put on the bar, the more strain you are putting on your knees. There is no give to a leg curl machine; it is made of metal, unlike your body. To avoid strain on your knees, keep the weight within a reasonable range. For lifting heavy weight, or competitive weightlifting, most athletes opt for barbell exercises like squats rather than loading down a leg curl machine. Heavyweight will also put a lot of strain on the machine.
q: Why do some machines have a prone position?
Being in prone position means you are laying down with your back in the air, facing forward.
Many leg curl machines offer the prone position as an option to reduce strain on your back. Additionally, many machines have the added feature of side handles you can grasp while working out in the prone position. This stabilizes you and helps make sure your hamstring muscles are doing all the work on the leg curl machine, as they should be.
