In this video it is stated that lengthening the foot stance increases gluteal load. However, this also forces a flatter back angle, when a lot of people say that it's important to keep your back upright when doing bulgarian squats.
Is increasing stance length and leaning a bit more forward a good way to increase gluteal load without introducing weights, or are there better ways to do this? Or should I just look for a different exercise to train glutes?
