So how do you choose the best leg extension machine?
We aim to answer that question and more.
We will cover how to use a leg extension machine and offer a few Leg extension workouts, plus briefly discuss if it is worth it to buy a leg extension machine. We will finish with a review of 5 machines we think are gym worthy.
What is a leg extension?
A leg extension is an exercise done in a leg extension machine. Obviously.
How it works. You sit in the machine, hoot your feet behind the feet pads/rollers, hold on to the handles and extend your legs out, lifting the weight.
What muscle does the leg extension work, and how will that benefit me?
Leg extensions are an awesome quads Isolation exercise.
This exercise targets the quads and adds detail and definition to the front of the leg. This looks sexy on men and women and this exercise is good for everyone.
Will Leg extensions hurt or damage my Knee?
NO! Not if done properly.
Proper Leg extension form:
- Knee MUST be in line with the pivot point
- Back of the knee must be flush against the edge of the seat
- You back need to be against the seat pad
- The foot pad needs to be in front of your ankle, touching the foot.
- Putting too much weight causes you to engage other muscles and defeats the purpose. It is also dangerous and more likely to damage the knee.
- Focus on ONLY using Quads during the move. Use tactile stimulation to train your muscles only, to engage in the exercise.
Warning:
Less is more with the leg extension. Use less weight than you can lift. The reason injuries happen on the leg extension is too much weight used, stressing the knee joint.
Most people can list a heavy amount of weight on the leg extension. In this case, just because you can, does not mean you should.

But that’s not all
He covers how to achieve the correct form, and demonstrates poor form as well, so you are sure to target the correct muscle without damaging your body.
Can I use the Leg Extension machine for any exercise other then Leg extensions?
So glad you asked.
YES!
Video below Shows Arlene Avery demonstrating a novel glute exercise using the leg extension machine. She performs an exercise known as the Hip thrust on the machine.
Big Booty Tip: Hip thrusters are such an awesome exercise because they work the glutes WITHOUT making your thighs bigger.
This machine is for guys too!
Men, Jay Cutler, 4 time Mr. Olympia Demonstrates the leg extension.
Jay has legs that look like He-man, and he says leg extensions are a great way to warm up the knees and target the quads.
He offers tips to fine tune the move, how to time the exercise, and how many reps to perform.
Is a leg extension machine worth it?
Yes, we think so. Some home gyms include the leg extension in their all in one machines but…
Here is the deal:
If you have an all in one machine that adjusts properly, this may be OK.
But the Truth is:
Many all in one gyms do not adjust well, and as we stated before, adjustment is so, so, so important when performing leg extensions.
- Your knees must align with the pivot point.
- The back rest MUST be adjustable because not everyone has the same length legs. Many all in one gyms do not adjust enough to get into a good position for the leg extension.
All in one gyms seem like a good idea, but unless they adjust to fit YOUR body mechanics perfectly, then all the features and exercises it has are useless.
What to look for in a leg extension machine
As we have started several times, the best leg extension machine must be adjustable to fit you.
The seat pad, back rest and foot pad must be adjustable in a range wide enough to accommodate the length of your limbs.
Look for a machine that sits firmly planted on the floor. There is nothing worse than a machine that wobbles and feels cheap.
A Crappy machine will mess with you mentally, throw you off your game, and in the worst case, break while you are using it!
Look for pads that are washable, comfortable and built to last. Vinyl covered foam rollers are a nice touch because they are more washable than the foam roller pads.
Does it include weight? If not what type of weights does it accept? Standard or Olympic?
Made sure it is compatible with what you have, or has an adaptor available.
Get more bang for your buck. Some machines can be used to perform several exercises. If value and getting a good deal are important to you, find a machine like this.
