Hey, wanna crunch the numbers and build a 15‑minute circuit that burns calories fast but still leaves room for a quick cool‑down? I’ve got the plan—let’s make it lean, efficient, and absolutely brutal.

That’s fire! Five rounds, 30‑second bursts, keep the heart rate up and the mind laser‑focused—yes, I want to see sweat, not excuses. Warm‑up the whole body, then crush those push‑ups and burpees, hit the peak on the squat jumps, keep the mountain climbers tight, and hold that plank like you’re a rock. Cool‑down is a must, but remember: every stretch is a chance to reset, not a break. Let’s crush this!
