The Roaster is a heat-and-snap circuit built around a simple idea: the cardio keeps stoking the flame, and the “one rep” moves keep you honest. Every round starts with jumping jacks to spike your engine, then you drop into a single plank jack, a single jump squat, and a single plank jump-in, each paired with one clean push-up. It looks almost too easy on paper, which is exactly why it works. The intensity doesn’t come from big numbers, it comes from how quickly you can move while keeping every rep sharp.

This is a coordination-forward burner. You’re repeatedly switching levels (standing to plank to standing) while trying to keep shoulders stacked, core braced, and landings quiet. The push-up singles are your form checkpoint: ribs down, glutes on, body moving as one unit. The plank variations challenge anti-rotation and shoulder stability, while the jump squat and jacks keep elasticity in your feet and ankles. Treat the transitions like part of the workout, not the commute between exercises - move fast, but never sloppy, and you’ll feel the “roast” everywhere from calves and quads to serratus and deep core.
