Are these the toughest workouts EVER? From online bikini body training to candlelit dancing, FEMAIL puts the hottest fitness classes to the test to find the programs that will keep YOU trim and toned this summer

Experts claim it is not too late to get in shape for summer with the help of the right fitness class, the right diet and enough sleep, without having to slog it out solo in a gym. 


Research shows people work harder in a group so FEMAIL tested some of the latest classes on offer in the US to see whether they really work. Three writers tested all manner of options, from bootcamp sessions with male model Akin Akman (bottom left) and dance cardio workouts with Madonna's former trainer Nicole Winhoffer (top left) to 'movement training' at Tone House (bottom right) and 'dance-letic' aerobics classes KGBody (top right).
