“An absolute sweat-fest. The intervals are short but intense, so you're always working at your limit. The group energy is the only thing that keeps you going.”
Pro Tip
Wear supportive cross-training shoes designed for lateral movements. Bring a sweat towel, keep your water close, and pace yourself during the first few intervals.
