Alex Verdugo Jr., the mastermind behind the Extreme Fitness conditioning system, helms a team of certified Russian-kettlebell personal trainers who help clients build muscle and incinerate calories using kettlebells, BOSU balls, and TRX suspension. The kettlebell, central to the Extreme Fitness program, is said to burn up to 20 calories per minute. During 45-minute high-intensity classes, the body works as a unit as weights and suspension apparatuses strengthen the core and build the abs to withstand the punches of skeptics and the impact of low-flying birds. Inside the green and silver gym, plenty of floor space allows students to stretch out with enough room to swing kettlebells and rehearse bell-ringing routines.

Though Extreme Fitness sometimes features a discounted price online, this Groupon still offers the best deal available.
