How to do barbell squat
Master the setup, range of motion, and tempo for safer, more effective reps.
Overview
Building lower body strength starts with the ability to sit back and stand up under load. This movement recruits the quads, glutes, and core to work as a single unit. It teaches you how to create tension throughout your entire body to move heavy weight safely and efficiently.
Why Use It
- Develops massive lower-body strength and muscle mass.
- Increases bone density and strengthens connective tissues.
- Builds exceptional core stability and bracing power.
When to Use It
This should be the centerpiece of your leg day. Perform it at the beginning of your workout when you are fresh.
Instructions for Proper Form
Setup
- The Rack: Step under the bar and pinch your shoulder blades together to create a shelf.
- The Unrack: Stand up to lift the bar, take two small steps back, and set your stance.
- The Brace: Take a huge breath into your belly and squeeze your abs hard.
Execution
- The Descent: Push your hips back and bend your knees at the same time. Keep your weight over your mid-foot.
Pro Tip: Drive your knees out against an imaginary band to keep them in line with your toes.
- The Bottom: Go down until your hip crease is below the top of your knee.
- The Drive: Push through the floor and drive your upper back into the bar to stand up.
- The Finish: Stand tall and reset your breath for the next rep.
Coaching Cues
- Brace your abs like you're about to be punched
- Sit back into a chair
- Drive the floor away
Common Mistakes
- Knee Cave: Letting the knees collapse inward, which puts stress on the joints.
- Heels Rising: Shifting weight to the toes, which reduces power and stability.
- Hips Rising Too Fast: Letting the hips rise much faster than the shoulders, turning the squat into a lean.
How to Fix It
- Knee Cave: Drive your knees out toward your pinky toes as you descend and ascend.
- Heels Rising: Screw your feet into the floor and imagine grabbing the ground with your toes.
- Hips Rising Too Fast: Drive your upper back into the bar as hard as you push with your legs.
