305 Fitness brings us a leg and booty routine set to a range of Lizzo songs. I tested this out at home and the series of squats and lunges got my quads extremely fired up. Holding the lunges and squats in between the other variations is what really got me. I did it as a burnout at the end of my workout, but you could replay the video a few times and even add weights if you wanted to challenge yourself more.
