How to Choose the Best Leg Extension Machine – Buying Guide

The Marcy Impex Weight Bench vs. The JYKJ Weightlifting Bench

Now that we’ve taken you through the best leg exercise equipment the market has to offer, it’s time to decide which machine you’ll be taking home.

Choosing from so many good options can be tricky, so we’ve put together a comprehensive buying guide to help you through the selection process!

Once you’re through, you’ll have no doubts about which the ideal option for you and your fitness goals.


Above all, safety should be your top priority. Leg extensions enjoy continued popularity for the quick results they offer, but they also present some serious health risks that you must consider.

While the exercise is great for building and toning the quadriceps, it will also place strain on your knee ligaments in the process.

If you suffer from a prior knee injury or any sort of degenerative bone disease, a home leg extension machine is probably not in the cards for you.

Be sure to chat with your doctor before investing in a machine you can’t use!

Another common mistake people make is lifting too heavy, too soon.

Lifting heavy can be an enthralling experience for gym enthusiasts, but a leg extension is not the right movement to max out on – you’ll risk seriously injuring your knees.

Be sure to start low and go slow with the weight you choose. As resistance increases, don’t forget your form.

Proper Form

When sitting on a leg extension machine, make sure your back is pressed flat against the back rest.

Your shins should rest against the leg pads, with your knees flush against the seat’s edge. Check that your knees, legs and hips all line up at a 90 degree angle.

Finally, focus on lifting using with your quads only. If you feel that you’re straining and using other parts of the leg, you should remove resistance.

Go easy on your body when starting out – it will thank you later!

Quality & Durability

The best leg extension and curl machines can have steep price tags. That’s why it’s important to invest in quality – you’ll want something with guaranteed longevity.

Look for a machine that sits firmly on the floor with padded or rubber feet. – stability is essential to proper form and a good lift.

Without the proper grip or floor traction, your machine may wobble or shake.

Moreover, look into the materials used – double padded back and ankle rests will do wonders in terms of your comfort.

You should also keep an eye out for double stitching, which prevents the padding from ripping at the seams.

In regards to durability, most leg extension machines on our list are constructed with high-grade steel. Be sure the one you choose is built with a comparable material to ensure its strength and safety.

Versatility & Adjustability

Everyone has a different stature and build, so a machine with an adjustable seat is essential. No machine is one size fits all!

Most back rests have pop pins or sundial mechanisms for easy adjustment. The more positions available, the better your form will be.

Ankle rollers also often come with adjust pins. Remember to never have the ankle rollers rest against your knees – they must always be against your ankles, near the feet.

Remember to out the adjustment and assembly instructions provided by the manufacturer – often, images or tutorial videos are provided for the more visual learners.

FAQs About Leg Extension Machines

Q: What are the benefits of leg extensions?

A: Leg extensions are so popular in the fitness community because they are a quick and efficient way to isolate the quadriceps, which will gain you visible definition in the front of your legs.

Being a machine-assisted movement, they are great for beginners because they guide your form and posture, reducing risk of injury.

They are also useful to perform as a finisher, to accompany more complex and involved movements such as squats or dead lifts.

Incorporating leg extensions into your lower body workouts will really tone and strengthen your entire bottom half, and build explosive kicking power. (Which makes it the ideal exercise for soccer players or martial artists!)

Q: Can leg extensions hurt you?

A: Yes! Any exercise performed incorrectly can hurt you.

Leg extensions in particular can place unnecessary strain on the knee ligaments, especially if performed with a weight that is too heavy.

As a general rule, start low and go slow. There’s no point in maxing out on a leg extension unless your sole goal in life is to injure yourself.

Q: How do you do leg extensions safely?

A: Start with the proper form – back flush against the back rest, and shins against the leg pads. Your knees should be lined up at a 90 degree angle.

After selecting a weight, simply grip the hand bars and extend your legs outward until they are straight, without locking your knees or arching your back.

Then, exhale and lower the weight back to starting position.

It is best to start with a lighter weight and more repetitions. If you’re just starting out, don’t go above 3 sets of 12 reps.

Q: Can leg extensions help remediate knee pain?

A: Leg extensions are infamous for causing knee pain and injury, so in short, the answer is no!

If you’re feeling knee pain, the last thing you need is to put stress on your knees and patellar ligaments. 

Tips For Choosing A Leg Extension Machine

#1: Safety first!

Always check in with a licensed medical professional to ensure that your body can safely perform leg extensions. A doctor knows best!

#2: Maintenance is key.

Like all fitness equipment, leg extension machines require periodic inspection and regular maintenance.

Check for rusting parts, squeaking noises and irregularities in the range of motion.

#3: Remember your form.

Leg extensions can cause serious knee damage due to the amount of strain they place on the patellar ligament.

Make sure you’re performing the exercise correctly and playing it safe in terms of added weight load. It’s tempting to lift heavy from the get-go, but this will set you back in the long run.

If your weight is so heavy that it compromises your form, you should lighten the load.


Now that you know the criteria for selecting a good leg extension machine, it’s time to make the final decision!

No matter which product you choose, know that you’ll be getting one of the best on the market.
