Upgrade your leg workout with the Bulgarian split squat.

Want to build bulging quads, hamstrings, and glutes? You should! You may think that heavy squats are the only way to build a hulking set of legs, but there is another way, a way that is much more kind to your lower back—the Bulgarian split squat, also known as rear-leg elevated split squats.
The Bulgarian squat is a unilateral movement, meaning one limb is working at a time, which can help you fully develop your legs and help solidify hip strength. It is also extraordinary for balance because you call on your stabilizing muscles to support you in this exercise. Many people who have had back injuries or who have poor squat form due to flexibility or range of motion limitations have found that Bulgarian squats are equally effective as squats when it comes to hypertrophy. Research data from the International Journal of Exercise Science states that similar lower body muscle activity can be achieved using the RLESS with half the load of a traditional back squat which would likely result in a less compressive force on your back.https://www.youtube.com/watch?v=w4OUtEO27UM
Do you want more emphasis on your hips, glutes, and hamstrings? Simply lengthen the distance between your front and back foot for this exercise.
