Our personal trainers and coaches develop a plan unique to your goals, your schedule, and your lifestyle that will help you be the person you want to be. Ongoing nutrition coaching, planning, and modification is an essential part of the process… and entirely complimentary for our clients.

We are because everyone deserves to be healthy and confident… people of every shape and size and ability!

WHAT our CUSTOMERS SAY

  • Xavier, Weight Loss King

    “Since I started boot camp training at Underground Fitness, I’ve lost a total of 13 pounds. Thanks to the trainers, I have a better understanding of nutrition. My man boobs aren’t in the way as much so trainers Jake, Scott, Brian & Monica must be doing somethin’ right! :) Be prepared to give it all you got and leave knowing you had an awesome workout. I highly recommend this gym if you’re in the Central Phoenix area. Cheers.” *

  • Terry, Marathon Runner / Former Desk Jockey

    “The training regiment that Jake has provided is helping develop my upper-body strength where I previously had none, along with working on my balance and coordination. Jake has helped me concentrate on my core muscle groups, getting me to focus my weight and movements to reduce unneeded stress on my body and optimize my energy output. I set out with the simple goal of running a half marathon by the start of this year. I have done that now three times, and also tackled the marathon. I just feel better overall, and I am in the best shape that I have ever been in.” *
