To perfect your Bulgarian split squat, adjust the position of your front supporting foot (by moving it forward or backward) according to your own comfort and unique morphology.

This recommendation is entirely relevant and scientifically validated. A laboratory biomechanical study (type of evidence: observational) conducted by Song et al., published in 2023 in the journal *Frontiers in Bioengineering and Biotechnology*, specifically examined the impact of foot spacing during this type of exercise. By measuring muscle activity and exerted forces, the researchers observed that stride length radically alters flexion angles and the load on the hip and knee. A longer stride therefore engages the gluteal muscles (hip extensors) significantly more, while a shorter stride shifts the focus to other areas of the knee. Adapting this positioning to one's own morphology is therefore scientifically justified for optimizing training sessions while respecting joint comfort.
