With Weights on Wheels, a master personal trainer rolls up to your door in an 8½-by-20-foot custom trailer, delivering an inspiring workout space. Clients step in and follow through a personalized training session tailored to their abilities and goals.

It’s convenient, and it’s for anyone preferring privacy over working out to an audience at a public gym. So, at 5 a.m. before work, or at 5 p.m. in a busy schedule when supper’s heating up, clients are running out and getting a jump on fitness.
