A mosaic-tiled front desk welcomes gym-goers into Element Fitness, where modern facilities, advanced machines, and motivational group classes guide fit-seekers to health. The main gym floor basks in the glow of lime-hued walls that envelop a fleet of cardio equipment, including ellipticals, cross-trainers, and treadmills. Nearby resistance-training machinery and hand weights mold muscles and turn calories into a sweaty sacrifice. Element Fitness also corrals camaraderie-centric exercisers into more than 80 weekly group classes. Amid the calming water of the gym's pool, aquatic sessions swaddle achy joints in submerged resistance training. For a more intense calorie ousting, spin classes strap students onto a cycling bike for endurance and speed training. Element Fitness also instructs weightlifting, yoga, and SilverSneakers sessions, which cater to discarded trophies hoping to get back into the game.
