When it comes to building size and strength, squats are far better and efficient option than leg presses. Squats are far more complex lifts and when performed correctly will deliver better results. Below you will find specific reasons:
I) When compared with leg presses, more muscles are working during the squad and therefore you’ll burn more calories;
II) By doing squats you place your core under considerable stress, causing it to work hard to support your body during the lift. The result – your abs and core a getting a better workout when compared to crunches.
III) Squats requite the whole body to work during the lift, engaging more muscles, and developing more strength, power and muscular gains throughout the body.
IV) Most leg press machines focus primarily on the quads, eliminating the glutes from the lift altogether. More than 85% of people already have stronger quads than hamstrings and glutes, so training quads only will amplify the muscular imbalance between opposing muscles front and back, leading to knee injuries and low back.
