Body Empowered Fitness, Chicago

Inside an open-floor gym stocked with treadmills, weights, and bikes, Body Empowered Fitness's personal trainers bolster clients' bods with custom workout regimes and specialized exercises. The gym's staff, including owner and NASM–certified corrective-exercise specialist Sylvia Knilans, constructs fitness plans that utilize Simultaneous Functional Training, a fusion of strength and stamina exercises, to slim figures and build muscle without radioactive spider bites. Trainers share their knowledge with up to four participants at various points throughout each workout and catalogue the day's progress for future exercise regimes.
