  • I have been working out with Jake for 5+ months to get back into shape and to look my best for our upcoming wedding. Jake has really pushed me, but always kept me safe and injury free. He is a consummate professional. I would highly recommend him to all! (Meagan P.)

  • 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 […]

  • “There is absolutely no way someone can go from literally sitting on their couch in the worst shape of their life on January 5th to running the Boston Marathon on April 21, especially at 42 years old,” I said to Jake Maulin  on the first Monday, January 6, of 2014.  Jake replied, “you can, if you want […]

  • Hi My name is Patty. A few years ago I ran my very first marathon; in St. Louis, MO (the GO St. Louis Marathon) and around mile 21 you (Jake) inspired me to keep going, as I was thinking I would not finish. At the finish line you congratulated me, even stopped and took the […]

  • I trained with Jake for several months and think that he’s a great personal trainer. I used to think that I couldn’t run more than a mile but after training with him, within 2 months, I ran my first sprint triathlon and then did it again a month after. He helped me get to a […]

Jake has transformed the way I approach exercise and over all wellness. Jake’s high energy, high impact, results driven exercise programs that are […]

  • I have worked with other personal trainers and I benefitted most from working with Jake. He had a good plan for how he would progress me to the next level. 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 […]

  • I don’t even know where to begin, Jake has played an instrumental role in changing my life. After ” letting myself go ” and using all of my medical “conditions” (Thyroid, PCOS, etc) as an excuse Jake made me feel confident again, like the athlete I was/am. I was terrified to get back into the […]
