Leg curl and leg extension machines exercise leg muscles on different sides of your legs. Leg curls work on the back of the leg (Source).

This posterior leg exercise requires that you sit or lie down as you bend your knee (Source).

Leg extensions require that you straighten your leg against weighted resistance, exercising the muscles on the anterior or front of the leg (Source).

Purchasing a dedicated leg curl and extension machine for your home gym can be a great way to rehab a knee or leg injury, or to focus on developing your hamstrings and quadriceps for enhanced speed, balance and coordination (Source).  

The Bottom Line

The best value buy is the Marcy Utility Bench- it provides leg extensions and leg curls, while also adjusting to incline, flat and decline configurations. It's not as sturdy as some of the other, more expensive options, but if you're on a budget it's a solid option.

As opposed to the Marcy Bench, the Body-Solid and XMark are seated-style leg extension & curl machines, while the Deltech is really an Olympic bench that includes an integrated leg extension and curl functionality.

The Powerline, like the Marcy machine, is a bench-style option, but is higher-end, sturdier and easily handles up to 250 lbs for quadricep extensions.

Bestseller No. 1
XMark Functional Trainer Cable Machine with Dual 200 lb Weight Stacks, 19 Adjustments, and Accessory Package XM-7626 (Gray)
  • Hands down the XM-7626 is the most versatile piece of equipment for your family's home gym. Easily adjusts for anyone in your household, whether young or old, short or tall.

The XMark leg curl machine features a 12 position thigh pad, a 20 position press arm and a fully adjustable backrest pad.

Besides leg curls, it also provides leg extensions- and buyers say that it was relatively easy to assemble.

Unlike the Mary leg curl machine, it's a sturdier build that accommodates heavier weights without wobbling.

Plus you can load weights on its back to ensure it remains balanced. You might find that if you're doing heavy leg work that you'll max out 45 lb. plates on it.

One buyer told us, though, that he loaded it with 300 lbs and as long as it was properly counter-balanced with weights on its back, it didn't become insecure. In addition, buyers commend the quality of the padding as well as the responsiveness of the customer service. Overall, a great addition to home gyms.

What Are Buyers Saying?

The Marcy Utility Bench

The first leg curl machine we look that is the Marcy utility bench- it features adjustable backpack that can be configured into six different positions to accommodate a variety of different bodybuilding and workout routines.

Great for lying hamstring curls and seated leg curls, it's designed to provide a comprehensive workout and muscular development of your leg- utilizing a dual position leg developer to give your lower limbs a strong and strenuous workout inside your own home.

It features a handle at its front and when used together with its wheels makes it simple to maneuver around inside your home. The sawtooth adjustments enable you to finely tune the positions of your leg curling workouts.

Besides functioning as a leg curling workout bench, since this utility bench goes all the way back to an incline, you can perform a variety of dumbbell and bodyweight exercises on it as well.

  • It has received some mixed feedback, however, with one buyer complaining that the bench was unstable when using heavier dumbbells and barbells with it.
  • Another reviewer said while it was pretty simple to assemble, he criticized the leg extension padding as well as how inappropriately close the two legs are, which made it difficult to perform exercises effectively.
  • As well, the backrest felt insecure, there wasn't any padding for the bolts and caps, and the bench has a habit of tipping right and left as well as forward and back, especially when the leg extension is loaded up with a 45-pound plate.
  • That said, other buyers had more reasonable expectations for this relatively inexpensive workout machine, saying that if you are on a budget and want a relatively easy way to perform leg curls while on your stomach, this could be a good option.
  • Another home workout enthusiast says that it is relatively sturdy, pretty adjustable and decently comfortable- even though he is taller than 6 feet he says it's been able to accommodate his height and enable him to perform a variety of exercises.
  • Other reviewers say that if you bolt it together securely that it doesn't feel insecure and you can always tape sections of it to reduce sharp edges and friction if they are occurring.

The Body Solid Leg Curl Machine

The second leg extension & curl machine we looked at is manufactured by Body Solid- it is an adjustable machine that is designed to accommodate users of different sizes and heights.

  • Buyers tell us that you can't do laying hamstring curls on this, however, you can do seated hamstring curls-plus it's pretty simple to transition from leg curls to leg extensions.
  • Buyers were fairly impressed with this leg extension curl machine, saying that it is a quality build with easily adjustable positioning and comfortable padding.
  • One buyer purchased it to install in his basement as part of a physical rehabilitation regime, saying that it has been essential to keeping his legs exercised and developed.
  • Another reviewer recovering from a sports-related knee injury says that it has been essential to his physical rehab, keeping his knee strengthened as well as helping to rehab a torn meniscus.

The XMark Leg Curl Machine

The third option we examined is the XMark rotary leg curl and extension machine. It features an adjustable thigh pad as well as an adjustable backrest and press arm inside of an 11 gauge steel frame.

  • Buyers recommend how easy it is to assemble, how little space it takes up, and the commercial-grade quality of its construction, though some reviewers found that they eventually maxed out its poundage.

The Deltech Combo Bench

The fourth option we examined was the Deltech Fitness Olympic Squat Combo Bench- this particular option is not a dedicated leg extension machine but does include one. If you're in the market for a more comprehensive and full body workout unit with a bench press- this might be a solid option for you so it will take up more space but the other options we examined.

The Powerline Leg Curl & Extension Machine

The final leg extension & curl machine we examined is provided by Powerline- it's marketed as a hamstring and quadriceps training tool that's great for the home gym. You can perform leg extensions and curls lying down operating its integrated a 1-inch diameter weight post, though you'll have to buy the weight plates and collar separately.
