Is this better than a free barbell split squat?

The Smith machine provides a fixed path of motion which increases stability, allowing you to focus entirely on muscle contraction rather than balancing the weight.

How far apart should my feet be?

Aim for a distance where both knees form approximately 90-degree angles at the bottom of the movement. A longer stride typically increases the stretch on the hamstrings and glutes.

Should I feel this in my back leg?

You may feel a stretch in the hip flexor of the back leg, but the majority of the tension and effort should be felt in the glute and hamstring of the front leg.

Smith Machine Split Squat Guide | Hamstring Focus

Learn how to perform the Smith machine split squat with proper form to build stronger hamstrings and glutes through controlled, stable movement.

How to Perform

Set the Smith machine bar to roughly shoulder height and stand inside the frame with the bar resting across your upper trapezius.
Unlatch the bar and take a long step forward with one foot while keeping the other foot planted behind you.
Lower your hips vertically by bending both knees until your back knee is just above the floor and your front thigh is parallel to the ground.
Maintain an upright torso or a slight forward lean to shift the emphasis toward the hamstrings and glutes.
Drive through the heel of your front foot to return to the starting position without locking out your knees at the top.
Complete the designated number of repetitions for one leg before switching your stance to the other side.

Common Mistakes

Placing the front foot too close to the body which causes the heel to lift.
Allowing the front knee to cave inward during the descent.
Using a stance that is too narrow, resulting in a loss of balance.
Leaning too far back and putting excessive pressure on the lumbar spine.
