The class that started it all. Kelly's result-driven, full-body session is designed to sculpt and tone from head to toe. Expect a mix of strength training and cardio-based movements that hit every muscle group while keeping your heart rate up, all synced to a playlist Kelly curates to match perfectly with the reps.

What you'll need: a set of 5 lb and 10–12.5 lb dumbbells (grab your 2.5s too if you've got them), a mini resistance band, a Booty fabric band, and a hand towel.

The flow: you'll start with a warm-up, move into a strength and bodyweight series, fire up the glutes with banded activation work, and mix in heart-rate spikes throughout to keep the burn going.
