Body weight training

According to an American College of Sports Medicine (ACSM) survey of more than 3,000 fitness professionals worldwide, body weight training is predicted to be the next big thing. “Expect to see it continue to expand in all movement experiences including both group and personal training,” says Carol Espel, Senior Director, Group Fitness and Pilates at Equinox. “Look for the comprehensive incorporation of gymnastics, adult jungle gyms, workout spaces that are uncluttered with weight machines and open for training, greater suspension training options, primal movements, and more programming that is less focused on standard weight lifting protocols.” In other words, those tried and true exercises that don’t require equipment—like lunges, squats, push-ups, and burpees—are here to stay, so embrace them.
