  • As an ex-personal trainer, it took a lot to humble myself and accept how out of shape I had gotten.  I hired Jake because there was no question that he not only loves what he does, but he walks the talk and knows training.  You won’t just pump iron, you will train like an athlete […]

I really enjoyed learning from him and I still use the techniques he gave me. Jake is passionate about what he does, receptive to feedback, […]

  • Jake is someone you can’t categorize as just a personal trainer. First session, most trainers will ask you what your goals are. Jake on the other hand examines how you walk, how you move and really looks at ways he can improve your athletic ability, flexibility and all around well being. With Jake he’s not […]
