Finally finally, after lurking to all those new exiting workouts during an injury that lasted 18 months, I'm doing the fusion challenge and just did day 3! With modifications and a breather here and there ,but I did a Tasha workout 🎉🎉 I did use a step as an incline too, for the burpees and mountain climbers, and pushups, but doesn't matter. Have to clean both my mat and the floor around from the sweat flying around 😱
