Smith Chair Squat
Smith Chair Squat Video Guide
The Smith Chair Squat is a lower-body strength exercise performed on the Smith machine, using the fixed bar path to build quadriceps strength while supporting stability. Unlike a free weight squat or barbell squat, the Smith machine bar keeps the torso upright and reduces balance demands, allowing beginners and advanced lifters to focus on technique. This variation mimics a chair squat and places the muscle group emphasis on the quads, while also engaging the gluteus maximus, hamstrings, and core muscles for stabilisation. The guided motion makes it ideal for lifters who want more stability, cleaner proper form, and consistent lower-body development.
How to Perform the Smith Chair Squat
-
Stand in the starting position with feet shoulder width and the Smith machine bar resting across your upper back muscles and shoulder blades.
-
Step slightly feet forward to find a stable squat position with the bar following a fixed bar path.
-
Lower into the chair squat by bending knees and hips until thighs are parallel to the floor.
-
Press through your heels and drive hips forward to return to standing.
-
Keep torso upright, arms straight gripping the bar, and maintain good form through the desired number of controlled reps.
GymNation Tip: Sit straight down like you’re finding a chair—keep your heels heavy and knees tracking forward to light up the quads without leaning back into the bar.
Personal Trainer Notes:
-
Keep feet flat and avoid letting knees cave inward.
-
Maintain a neutral spine with head forward and chest height steady.
-
The Smith machine squats work best when you control the tempo and avoid butt wink.
-
Using a Smith machine allows more stability, making it a great exercise for different fitness levels.
-
Re-rack carefully to protect shoulders and lower back.

Smith Chair Squat FAQs
Yes — the Smith chair squat is effective for targeting the quadriceps, improving hip mobility, and strengthening the lower body. The fixed path reduces balance demands, allowing clean technique and consistent muscle force production.
Smith machine squats work the quads, glutes, hamstrings, vastus medialis, and core muscles. Compared to a barbell back squat or free weights, machine squats offer many advantages for controlled leg exercises and accessory movements.
No. A Smith machine bar can weigh anywhere from 6–20 kg, especially on angled Smith machines or counterbalanced setups. Always check your gym equipment.
Absolutely. The fixed bar path provides more stability, reduces lower-back injury risk, and helps lifters maintain proper form compared to free weight squat variations.
The Smith variation uses a guided bar path, making it easier to maintain torso upright posture. A barbell squat requires more stabilizer muscles and balance, while the Smith machine supports technique and consistent tension across the thighs and hips.
