Smith Machine Front Squat vs Barbell
With traditional front squats, the bar wants to roll forward off your shoulders. But the fixed path of the Smith machine front squat helps to keep the bar in place.
In addition, the Smith machine bar is lighter than a full-size Olympic bar. So it’s easier for beginners just starting to build up strength.
One other benefit is that the Smith machine reduces the need for you to balance your body. This stable movement means larger muscle groups like the quads do more work.
Of course, the Smith machine isn’t without drawbacks. The lack of stabilizer muscle recruitment means it’s not as good for building overall strength and coordination.
