Table of Post Contents

How are your quads? Your hammies? If you’re looking forward to work on your thigh muscles, there’s no other equipment that works like the best sissy squat machine. Although you can do sissy squats with no equipment, a machine will ensure your safety while doing it right.

Here, we handpicked 5 of the best sissy squat equipment that you can use on your workout. We suggest that you browse our buying guide first so you’ll have an informed pick later on.

What is a sissy squat machine?

A sissy squat machine was said to be named after Greek god Sisyphus. The gods punished him to roll a giant rock up a mountain and leave it on top. However, the gods keep rolling it back to the ground. Sisyphus will then have to start over. Depictions of Sisyphus include a well-toned set of quadriceps; thus, the name Sissy squats.

Far from the Greek story, a sissy squat machine is used to isolate the front quads so you can work it out even more. The equipment will also support your knee and calves to reduce the risk of injury. 

Most sissy squat machines are adjustable to suit the training needs of the user. Also, it can come with extensions for other muscle routines. 

How to Choose the Best Sissy Squat Machine

Purchasing the first sissy squat machine you see is convenient, but it deprives you of the chance to shop around and get the best value. So before we dive into the best options, take time to read the following points first. Trust us, we’ve been there and hasty purchases are a big waste of money. 


The built of the sissy squat should always be sturdy. With the vast amounts of force that will transfer from your quads, you can’t risk it in a shaky unit.

Always opt for heavy-gauge and thick steel. Also, all the components should be welded solidly together. If screws are used to join the parts, it should be durable enough to endure the force exerted during the squats. 

Also, it’s advisable to tighten the screws once in a while to make sure that your equipment is safe for your workout.


Look for soft padding that will cushion your knees and provide the support that you need. Also, avoid models that have padding that runs toward your front leg down below your calf. It can lead to chafing, which can be distracting during your workout. 

Most sissy squat machines have faux leather covers. Make sure that it’s well-stitched so it wouldn’t puff after a few sessions. 


The size of your sissy squat machine should be based on the leg room that you need as well as the storage space you have. Check the dimensions and compare it to your storage place. Those with large garages or home gyms won’t have problems with bulky equipment. Still, going compact have its perks too. 

Aside from the length and width, don’t forget to check the height. It’s often the make-or-break part when it comes to storage. 


A sissy squat should always stand firm during use. Stability is essential since it has something to do with the equipment’s safety. 

A loose screw or a wobbly construction can lead to injuries. You might tip your balance and smash your butt on the floor. Worse, you might break an arm or pull a muscle. That’s something you wouldn’t want to happen when you’re working out.

It’s best to purchase a heavy sissy squat. Yes, it’s cumbersome, but the added weight ensures that the equipment will stay in place while you perform your squats. 


We all come in various height and weight ranges so it’s just right that you get a sissy squat that you can adjust accordingly. If you’re buying the sissy squat machine for yourself, always get one that suits your body size –you might have longer or shorter legs than most.

Although you can save a few bucks on affordable machines, splurging a bit can go a long way. Look for a sissy squat with adjustable rear support and foot holder. And don’t try to improvise with a layer of padding. It will sabotage your stability and hurt your legs. 

Weight capacity

Each sissy squat is made for a specific weight range. Its no-brainer that if you weight more than 350 pounds, it’s not a good idea to purchase one made for a 250-pound user.

Sizing up the sissy squat machine to your body is important for two reasons: for your safety and your money.

This one’s obvious but a lot of people still overlook the weight capacity department. It will lead to frustration and a big waste of money.


It’s all about the amount you’re willing to shell out. A more expensive sissy squat machine has better quality and decent warranty terms. Also, most high-end equipment has commercial quality, ensuring your safety and value of your money.

Also, sissy squat machines that are in the pricier spectrum come with a lot of extras. Some have extensions that you can use for sit-ups and push-ups. 

Of course, not all of us have the budget to splurge on expensive sissy squats. You can look for entry-level types with a more affordable price tag, but don’t put your expectations too high.
