How to Do the Smith Machine Squat

Beginner legs exercise with machine.

The Smith Machine Squat is a beginner-level legs exercise that works several muscles together, led by the quadriceps, using machine. As a compound movement it lets you handle heavier loads and trains coordination across multiple joints, which makes it a strong anchor for a training day. It slots into most gym setups, and SSS Workout Assistant will program it automatically when it fits your goal and available equipment.

How to perform it

How to program the Smith Machine Squat

Do the Smith Machine Squat early in your session while you're fresh — compound lifts deserve your best energy.
Warm up with one or two lighter sets before your working sets to prime the movement.
As a compound lift, 3–5 sets of 5–8 reps builds strength, while 3–4 sets of 8–12 reps favours muscle growth. Rest 90–180 seconds between sets so you can move quality load.
To progress, add a small amount of load only after you can hit the top of your rep range with clean form.
