LONDON -- Move over, P90X: There's a new workout in town.
London-based fitness studio 1Rebel has launched a fitness class called "Rebels on Ice" that involves high=intensity interval training (HIIT) training on a slippery ice rink.
The added challenge of doing strength exercises on an icy surface forces your core to engage and makes your muscles work much harder to avoid falling over; your joints might ache afterward, but you're working toward increased flexibility. Its organisers claim the workout burns 500 calories in 20 minutes.
The class combines cardio and strength moves; attendees can expect a workout full of high knees, burpees, squats and lap runs on the ice rink. It works your glutes and quads, as well as your core.

Fair warning: You might come away with a few bumps and bruises.
The classes run every Thursday at the Broadgate Ice rink at 1:15 p.m. and 5:20 p.m. Tickets cost £13.49 for a 20-minute session; you're advised to wear running trainers with decent grip and gloves for safety purposes.
