Helping a friend move. Spryly climbing stairs. Jogging with the dog. To the trainers at LivFit Nutrition and CrossFit Anax, physical fitness is all about increasing your day-to-day functionality. To that end, they lead a daily-changing regimen of classes that focus on strengthening everyday movements, such as running, lifting, pushing, and waving away pollsters on the street. Instead of overseeing armadas of elliptical machines or treadmills, they engage patrons in games of toss with medicine balls and send them sprinting, heaving kettlebells, and dropping for push-ups. They mix up activities each session to stave off the boredom of repetition, keeping everyone involved and meeting their fitness goals. These trainers know, though, that total body fitness is only possible with a nutritious diet, so they also guide their monthly members to better eating habits with monthly check-ins.
