Please wait... @mollybsims : Okay ladies, let’s get bikini booty ready together 💪🏼 Since the beginning of 2019, I’ve been a HUGE fan of HIIT workouts — that’s high intensity interval training for those of you who aren’t familiar. It gets your heart rate up & burns more fat faster than anything else I’ve ever tried. 😅 I finally found a workout that works for me. @lauralizkeller is sharing one of the routines we do during our morning sessions & I’m telling you, it’s NOT easy. Watch the full workout at the link in my bio 💦💦💦
