Smith machine bulgarian split squat

The Smith machine Bulgarian split squat is a single-leg squat with the rear foot elevated and a guided bar path for extra stability. That support makes it easier to focus on the quads and glutes without losing balance. It’s a strong choice to build unilateral leg strength, fix imbalances, and improve hip and knee control.

Instructions

Position one foot in front and the other on a bench behind you, with only the front part or top of the back foot resting on the bench
Keep your torso upright, ensuring the front foot remains flat on the floor while the back foot is supported on the bench
Place the guided bar on your trapezius
In a controlled manner, flex your hips and knees, lowering as far as possible while keeping your front foot firmly on the floor
Then, return to the starting position by extending your hips and knees

Tips

Keep your torso upright and avoid leaning forward excessively; a slight forward tilt is acceptable
Avoid letting your front knee collapse inward; maintain alignment with your hip
Avoid using momentum or sudden movements

Restrictions

Avoid if you have acute knee pain or major instability. Limited ankle/hip mobility, obesity, or older adults should start with a shallower depth and light load, focusing on knee tracking over the foot. If you have low-back pain, brace the torso and reduce load. After recent injuries, consider professional guidance.
