Challenging but achievable. I have lost 20 lbs this year with the help of OTF. The coaches are awesome. Especially Ezra and Rashida. The fact that Ezra remembers to shout people out for their birthday says a lot. He is a great head coach.
I have never worked out before in my life (whisk I'm not proud of), but since I joined OT I love it. It has being challenging and in general a great way to become the active person I always wanted to be.
