Smith machine squat
Log this in the trackerA squat on a fixed bar path, useful for training close to failure without a spotter.
What it is
A squat where the bar runs on rails, so balance is handled for you and the set becomes a question of leg strength alone. The fixed path is the trade: it also stops you finding your own groove.
Muscles worked
Primary: Quadriceps, Glutes. Secondary: Adductors, Hamstrings, Core.
How to perform it
- Set the bar on your upper back and place your feet slightly ahead of the bar, not under it.
- Rotate the bar to un-hook it and take a breath into a braced trunk.
- Squat down until your hip crease is level with the top of your knee, or as deep as you can hold position.
- Drive up and re-hook the bar only when you have finished the set, never mid-rep.
Common form faults
- Feet directly under the bar, which forces the knees forward and the heels up. Walk the feet forward a few inches so the rails carry the load down your body, not through your toes.
- Leaning on the safeties instead of bracing, because the machine cannot tip. Brace as you would under a free bar. The rails hold the bar, not your spine.
Programming
Good for higher-rep quad work and for pushing a set to the last rep alone. Around 8 to 15 reps. Keep at least one free-weight squat or hinge in the week too.

Frequently asked questions
- Is the Smith machine squat worse than a barbell squat?
- It builds the legs perfectly well, but it trains less balance and stabilisation, and the fixed path suits some bodies better than others. Use it as a variation, not as your only squat.
- Why do my knees ache on it?
- Usually foot placement. If the feet are too far back the knees take the whole range; walk them forward until the shins stay quieter.
