Front squats? Are you surprised?

They  Build a Stronger Core 

The position of the bar and upright torso works the front of your core (abs and obliques), and helps build the core strength you need to handle heavy weight in other lifts, such as the Back Squat or Deadlift.

 

The front squat builds phenomenal strength in the core, glutes, hips and legs; all areas that are involved performing nearly every other movement in the gym, sports, or life. Like the name implies, the front squat is done with the bar placed across the front of the body.
