"The Leg Press is a great substitute for a Squat" 🤔
There are a hell of a lot of myths and legends around training, particularly when it comes to lifting weights. An old myth, but one that is still circulating is that if you can't get access to a squat rack, a leg press is a good alternative as you work the same muscles.
For a start, if you can't access the squat rack to train, it sounds like you're in the wrong gym!
If a PT suggests that you leg press instead as it hits the same muscle groups, you are definitely in the wrong gym!
So, what is the difference?
A squat is a primary movement. And, just to be specific, we are talking about a good old barbell back squat. It is a primary movement because it hits everything from your shoulders all the way down to your toes. For a start, before you even begin, you have to load the bar. Most of the time, loading the bar is a workout in itself! Once loaded, you have to unrack a barbell on your shoulders. The bar has to be placed in the right position on your back and to do that you have to have your grip in the right position and create a shelf with your shoulders. So, this upper back area has to be engaged. You then have to walk back with the bar on your shoulders. It may be just a couple of steps, but while you are taking those steps, you have to stabilise the weight you are carrying - using your core. Next, you have to squat, taking the bar from a standing position down into a squat position and then stand back up again. A correctly performed squat balances all the forces around the core, knees and the hips, and uses all of the muscles in these areas exactly as they are meant to be used over the squat's range of motion. Again, as a primary movement, a barbell back squat is an authentic - there is no compensatory factor, it is just you and the weight on the bar. The barbell back squat is also magical in that its metabolic affect increases overall strength, systemically, on the body, which means that the body adapts as a whole even though its referred to as a leg exercise (another myth).
Now, for the Leg Press. The leg press, particularly the 45 degree presses that most commercial gyms carry, are particularly comfy affairs. They have a nice padded seat and handles to hold on to, so you can make yourself at home. You may have to select the weight you want to press by removing a pin or selecting a weight to start. So, you sit down in the leg press, put your feet on the plate, unrack the press and push. There is no weight on your shoulders, as with a barbell back squat, and barely any core engagement. You are not having to walk out in the leg press, you can just sit there so no stabilisation needed! As you press with your legs, you do not engage the same amount of muscles as a squat because you are not moving a weight through the same amount of time and space, you are just pressing the weight with your legs. It's not a natural movement like a squat is. And to top it all, when you use a 45 degree leg press, the angle of the press compensates for the amount you are pressing, so it's not a "true" weight.
