  • Personal Training at it’s Best

    Ashley Hoover,

    I’ve been to several different Gym in the past and by far this is my favorite!! The personal trainers are very knowledgeable. I highly recommend Cody for as a trainer. He taught me how to work out correctly and he would update the workout routine for maximum impact and results. The classes they offer are actually fun. Mixing in some awesome unique activities to the classes. My favorite the Bosu ball and battle ropes.

  • ONYX is the BEST

    Kelly Radeff,

    ONYX is the BEST gym around. Nothing like a commercial gym, the staff is so personable and friendly. Brand new equipment being added, always clean and the members even take pride in taking care of the gym(the weights are always re racked or equipment back in its place)! Perfect environment to get a work out in!

  • Ask for Ryan

    Michael Anthony,

    ONYX Health Club in Northfield is a great facility with even better staff! From strength training to cardio equipment this is truly a one stop shop. I can't imagine how great the facility is going to be once the renovations are done. The new free motion machines are state of the art. If your ever in the area and need to get a workout it's worth the stop. Just ask for Ryan!
