Front squats mainly work your quads , but they also hit your glutes, core, and upper back hard for stability and posture.

Quick Scoop: What Do Front Squats Work?

Think of the front squat as a “front-loaded” leg and core builder that forces you to stay upright. That bar across your shoulders shifts the emphasis a bit compared to back squats.

Primary Muscles Worked

  • Quadriceps (front of the thighs) – biggest winner here; the upright torso and knee bend make your quads do most of the heavy lifting.
  • Glutes – especially as you drive up from the bottom and lock out your hips.
  • Adductors (inner thighs) – help control knee position and stabilize your legs.

Secondary / Support Muscles

  • Core (abs and obliques) – works isometrically to keep your torso upright and prevent you from collapsing forward.
  • Spinal erectors and lower back – help keep your spine neutral under load.
  • Upper back (traps, rhomboids, lats) – work to keep the bar in the front rack and stop your upper back from rounding.
  • Hamstrings – assist with control and hip extension, but are less stressed than in a back squat or deadlift.

What This Means For Your Training

  • If you want more quad focus: front squats are a top pick versus back squats because they bias the quads more.
  • If you want core and posture gains: the front rack position forces strong core and upper-back engagement every rep.
  • If you want overall leg strength: you still get solid glute and hamstring involvement, just with slightly less posterior-chain emphasis than heavy back squats.

Mini FAQ

  • Are front squats for quads or glutes?
    Mostly quads, with glutes kicking in hard out of the hole and at lockout.
  • Do front squats work core?
    Yes, a lot – your abs, obliques, and upper back have to brace to keep the bar from tipping you forward.
