Festival season is around the corner and Lizzo is already getting prepared. The singer, who is set to headline at Bonnaroo and Outside Lands this year, has given her fans a peek at how she is preparing via Instagram.

Lizzo posted a video on her Instagram story of her trying out a new treatment as part of her strength-focused workout plan in preparation for her upcoming performances. In the video, she is lying down with a device wrapped around her waist that appears to target her core.

In the caption, she tagged EllEve Medical Spa in Los Angeles, writing “@ellevemedspa pre-workout ab flex gotta get strong for festival season!”

During EMS treatments, a conduction pad is placed on the body which delivers high-frequency electromagnetic energy and causes the targeted muscle area to contract. EMS is often used to loosen tight muscles or to increase the intensity of exercises before a workout.

EMS treatments assist in boosting strength, as well as toning and firming muscles. Other celebrities such as Kim Kardashian, Chrissy Teigen, and Drew Barrymore have raved about trying EMSCULPT and EMS workouts.
