Created by Royal Ballet-trained dancer Stephanie Burrows, POPfit combines pilates, plyometrics, yoga and dance into routines set to loud pop music, so you get the best bits of each of these disciplines, without the need for any equipment, and you get to have a laugh too. The classes range from Popfit Signature (cardio, strength and stretching) to POPfit Yoga to POPfit Barre to POPfit Dance Cardio. Word on the street is that Kate Hudson and Melanie C are fans, and if it’s good enough for actual Sporty Spice then it’s good enough for us.
