A New Study: Squats vs Leg Extension
(For Quad Growth)

Zabaleta-Korta (2021), The role of exercise selection in regional Muscle Hypertrophy: A randomized controlled trial, J Sports Sci.

The quadriceps is one of the biggest muscles in your body. It is one of your most important muscles in sports, and you cannot build a strong and impressive physique without them.

In a new 2021 study, 21 young men with strength training experience trained their respective exercise three times per week, doing four sets of twelve reps to muscular failure each workout.

Before and after the five weeks of training, the researchers used ultrasound to measure the cross-sectional area of the participants’ rectus femoris and vastus lateralis.

The study showed that the leg extension lead to significant more gains in the quads especially in the Rectus Femoris.

Awesome and easy to use

Great little product - love the fact that you can use the weights you already have which allows for overload.

It is a little finnicky to put on and the buckle system isn't the best but once you get used to it, are issues that don't detract from the experience from using it. Favorite exercise has been the standing leg curl, and the ANKR has been amazing for that.

Great, great product and kudos to Kensui. I use them in my classes and they have given me greater variety in delivering progressive loads to and in around the core, back, hip and knee. If they used the airboot teachnology for the next generation I think it would elevate this product even more, but for now myself and my clients are extremely happy with this.
