Front squats mainly work your quadriceps , but they also hit your glutes, hamstrings, core, and upper back quite hard.

Main Muscles Worked

  • Quadriceps (front of thighs) – primary movers; they work hardest because the upright torso position shifts more load to the front of the legs.
  • Glutes – strongly involved, especially as you drive up from the bottom and lock out the hips.
  • Hamstrings – assist in controlling the descent and help stabilize and extend the hips, but are secondary to the quads.

Core and Upper Body

  • Core (abs, obliques, lower back) – works isometrically to keep your torso upright and prevent you from folding forward.
  • Upper back and shoulders – traps, rhomboids, spinal erectors, and even chest and arm muscles help support the bar in the front rack and keep the chest up.

Simple Takeaway

If you think of front squats as a “legs plus core” lift, you’ll be on point:

  • Main focus: quads.
  • Strong support: glutes and hamstrings.
  • Stabilizers: core and upper back.
