What do G&G customers say?

Thank you for helping me pick out the perfect treadmill. It’s so nice to be able to run on hot or bad weather days or late at night…it fits perfectly in my house and is just right for my runs. I’ve used it to keep up with my physical therapy schedule and I’ve lost over 60 lbs since I got the treadmill! Thank you!

I have 20 years of working in the physical education, coaching, and health profession. My experience with G&G Fitness has been unmatched. The staff went the extra mile by demonstrating superior equipment knowledge, as well as safe and effective exercise programming. Their unparalleled commitment to helping me meet the needs of my fitness program within limited space and budget was top notch.

Tom & Lori

In this competitive retail environment, customer service is extremely important. Karen and I appreciated your ‘non-pushy’ approach and expert advice when we were making our decision to purchase. The delivery and set up went fine, and so far....everything is going great! Thanks again for everything
