Slow Burn + Killer Core / PSA: There are NO lunges or squats in this workout… Can I get an AMEN. In fact, the entire workout is done down on the mat for a mat pilates/ barre inspired flow. All of the lower body work is focused on “accessory work” so will be done from a kneeling or lying position. This is a perfect workout for anyone who needs to take it easy on their knees.
