Smith Machine Split Squat
Muscles worked
Instructions
- 1To begin, place a flat bench 2-3 feet behind the smith machine. Then, set the bar on the height that best matches your height. Once the correct height is chosen and the bar is loaded, step under the bar and place the back of your shoulders (slightly below the neck) across it.
- 2Hold on to the bar using both arms at each side (palms facing forward), unlock it and lift it off the rack by first pushing with your legs and at the same time straightening your torso.
- 3Position your legs by placing one foot slightly forward under the bar and extending your other leg back and place the top of your foot on the bench. This will be your starting position
- 4Begin to slowly lower the bar by bending the knee as you maintain a straight posture with the head up. Continue down until the angle between the upper leg and the calf becomes slightly less than 90-degrees (which is the point in which the upper legs are below parallel to the floor). Inhale as you perform this portion of the movement. Tip: If you performed the exercise correctly, the front of the knee should make an imaginary straight line with the toes that is perpendicular to the front. If your knee is past that imaginary line (if it is past your toes) then you are placing undue stress on the knee and the exercise has been performed incorrectly.
- 5Begin to raise the bar as you exhale by pushing the floor with the heel of your foot mainly as you straighten your leg again and go back to the starting position.
- 6Repeat for the recommended amount of repetitions.
- 7Switch legs and repeat the movement.

About Smith Machine Split Squat
The Smith machine split squat combines the principle of a unilateral squat with the safety of a guided path. One foot elevated on a bench behind you frees up the range of motion of the front leg, which does all the flexion-extension work, while the guided bar removes the need to balance the load laterally. It's an excellent way to isolate each leg to fix strength imbalances, heavily working the quadriceps with the glutes and hamstrings assisting. The fixed rail makes this movement more accessible than its free-weight version for lifters who still lack balance, while keeping high intensity on the working leg.

lightbulbExecution tips
- lightbulbAdjust the bench distance so the front knee doesn't pass the toes at the bottom
- lightbulbKeep the torso upright and head up throughout the descent
- lightbulbPush mainly through the heel of the front leg
- lightbulbAlways finish on the weaker side last
warningCommon mistakes
- warningPlacing the bench too close, which dangerously reduces range of motion
- warningLetting the front knee cave inward
- warningLoading too heavy before finding the right foot position
- warningNeglecting the back leg, which should stay relaxed, not driving
helpFrequently asked questions
How far should the bench be placed?expand_more
Generally 2-3 feet, adjusted to your height to keep the front knee aligned with the toes at the bottom of the movement.
Should the back leg push?expand_more
No, it only serves for balance support; all the work comes from the front leg.
