Today I tried split squats just for curiosity, did a superset of 5 sets with barbell and 5 with dumbbells and then a dropset with dumbbells. I already did supersets and drops with normal squats but I've always only felt it in my quadriceps and a little bit in my glutes.
But with splits I have felt my hamstrings and quadriceps both burning from one exercise and I also noticed an absurdly incredible burn in my gluteus medius, actually this was the first time in my life noticing anything in the gluteus medius. Are split squats superior to normal squats since they seem to work more muscles?
