Trent and his stepson Aaron want to take their training sessions to the next level, so they hire Jax, a personal trainer, to help them both exercise at the gym. Jax has very positive energy and wants them to be a better version of themselves, offering different kinds of workouts for Aaron and Trent to try. He also adds a little extra of freeusing, the only way for stepdad and stepson to loosen themselves and make the most out of the session.
