The concept: Claiming to be Americas only mobile personal training concept of its type, GYMGUYZ finished 2016 with 100 open franchises in 18 states. It had just 20 franchised units in 2015. Weve grown quickly because of brand awareness and strong social media interaction with customers, says founder and CEO Josh York. GYMGUYZ comes where clients are for training. The business uses vans wrapped in red with its logo, stocked with 365 pieces of equipment including weights, medicine balls, ropes and resistance bands for training. On-site expert coaches bring workouts to homes, offices, churches, hospitals, senior care centers, parks or other locations. Individual sessions can run from $10 to $110.
