Has it happened to you, too?
The leg extension used to be one of those exercises that I would look forward to on a leg day.
But then it just became so tedious… and painful.
I suddenly sought some alternatives.
Exercises that would replace the classic extension, be a little less tough on my joints, and be a lot more interesting.
I’ve not even told you the best part.
These workouts can be done at home, and produce better results that build your quads and define them into your desired shape.
It was a bit of a challenge, but after some trial and error, and thorough research, I found my top 5 leg extension alternatives you can do at home with as little equipment as possible!
A common exercise in a gym-goers leg routine, this exercise is performed on a lever machine.
You sit in a slightly inclined machine, with a cylinder-shaped pad above the ankles. This is the main mechanism.
The movement entices an extension of your legs, hinging at the knees.
The result is a pretty insane pump in the quadriceps (AKa the quads), located in the front of your upper legs.
As I said before, though, it isn’t all well and good with this exercise and has plenty of negatives that make it not the most effective quad workout.
Getting bored of an exercise is not my sole reason for swapping it out for an alternative (although it can be a pretty good one – what’s the point of working out if you don’t enjoy it?).
There are 2 main reasons I believe are crucial to why you should reconsider using a leg extension.
An exercise that forces you to straighten your legs underneath a load is guaranteed to cause an unnatural amount of stress on your knees and ACL.
Although the ACL can withstand a lot more weight than a full-stack on the leg extension, it is almost guaranteed to cause some wear over time.
Compressive forces acting on the ankle, which only increase as your leg extends, result in the likelihood of an ACL or quadriceps tendon injury.
As the hamstrings aren’t working in support, the stress is therefore completely concentrated around the knee.

Leg extensions are great for isolating your quads.
However, with your legs, it’s always a good idea to try to encourage more of your leg into the workout.
A lot of the reasons you are straining your ACL and hence damaging your knees is because your muscles aren’t working in tandem.
As stated prior, your hamstrings are lacking any sort of movement so all the pressure is on your knees.
The movement isn’t practical for real life, either.
Unless you are purely working out for aesthetics, then the exercise shouldn’t be your go-to.
For strength, we want movements that require stability, thus creating a requirement for your core, and other muscles to help in the workout.
All of the exercises listed below activate not only your quads but other muscles in your leg and core. Let’s get into it.
These exercises have been chosen with at-home workouts in mind. Equipment such as resistance bands may be required but nothing that will break the bank is necessary.
For any exercise that you may find too easy with a resistance band or your body weight, then there are multiple alternatives you can use that are just lying around your house.
Items such as milk jugs filled with water, or even a backpack with some books inside, are amazing substitutes.
One more thing before we get into the alternatives.

One of the most similar exercises that you can get to the machine leg extension, this exercise targets the quadriceps while also requiring stability and balance.
If you are looking for an out-and-out replacement for the leg extension, then this is the one for you.
It’s not as taxing on the knees and makes for a more complex movement, rather than the straightforward machine extension.
This exercise can be performed seated, or standing.
If you are finding the knee pain still occurs when seated, take it to a standing exercise to engage your hamstrings and glutes.
I’ll take you through the standing exercise here, but to perform it seated, just add a chair in front of the band.
If you have ever performed a wall sit, you’ll know how much of a quad burner it is.
A real staple in a strength and conditioning workout.
This exercise is not so much of a size builder, most use it as a muscle endurance exercise.
However, If you are adding weight over time and progressively overloading, there’s no reason you can’t increase your quad volume either.
I love this exercise for its simplicity.
As long as you are sitting with your back against a wall and your knees at a 90-degree angle, you’re going to feel it.
Try to time yourself each week and see if you can improve every time.
You’ll surprise yourself. I know I did.
Even thinking about them makes me shudder.
This exercise is tough.
The split-squat is an elevated, single-leg squat that focuses on your quads, as well as burning the rest of your legs and core.
A real test of balance, stability, and mental strength.
Developing proper form is extremely important for this exercise, as doing it incorrectly can cause more harm than good.
Try to focus on keeping your back straight, with your body upright, and having the correct foot placement on the chair behind you, as well as on the floor in front.
It truly does target each quad like no other exercise, increasing strength, size, and overall balance of your legs and core.
I recommend everyone to put this exercise in their leg day, with beginners starting at a lower elevation, and more advanced gym-goers attempting higher to maximize the burn.
Okay, I cheated a bit here.
The squat is the ultimate leg exercise that will work every muscle in your legs.
Even better, it’s one of the most important compound movements for increasing your core strength.
The reason I have chosen this movement is, in fact, not entirely for the squat part.
My main reasoning was for the jump part you perform after it.
This exercise not only increases your leg strength but is great for your cardiovascular health as well.
If you fully extend your legs during the jump and squeeze your quads, you will feel an incredible burn that replaces the requirement for leg extensions. It also helps build the glutes, which is also an excellent reason to do this exercise.
The step-up is a fairly simple motion that mimics natural movements, such as walking up the stairs.
I then decided to superset this movement with the lateral step up, due to this replicating a squatting motion.
Both will therefore require a different part of the quad to work, resulting in a different burn in the legs.
Adding weight to this exercise will then require a mix of leg strength and stability, making this an excellent leg extension substitute.
To wrap up, I encourage every single one of you to change your workout to include one of these leg extension alternatives you can do at home, rather than a machine leg extension.
The leg extension isn’t always a bad thing, it can be great for targeting the quads.
Problem is, it isn’t worth the potential injuries you can obtain in your knees, or the lack of compound movements.
The leg extension alternatives are all great for targeting the quads while improving other aspects such as balance, posture, and stability.
Ultimately, our goal is to improve our bodies in the safest way possible, and leg extensions are not the best way to do that.
