When I started I couldn't even do five pushups. Now it's not a problem to do. That's how it's different. You've got somebody right there that is a trained professional that knows what they're doing, so you're not treated like a client you're actually treated like family.
I saw my muscle mass increasing and saw my body fat decreasing. They called it semi-private training, but it's a whole lot more than that. If you're on the fence, this is an investment in your future, in your relationships, all of it.
