Happy Clientele:

Great service and great product! The team kept me updated and made sure everything was what I was looking for. I have never experienced a way to exercise your stomach that is is more focused , easier to do, works the support muscles better, and is actually fun to use.

RICHARD B FLOHR - 10/24/2024

The experience with the company was good, I felt like they had a good order process and my machine shipped quickly. The installer said a piece was missing but once I reported it they sent the missing part right away. Nobody is perfect but I gave them 5 stars because you can tell take service seriously.

Travis Davis - 10/02/2024

Very high quality kettlebells, highly recommend. I am very pleased with the service at Select Fitness. They were very responsive to my many questions and unique order situation. These kettlebells are top notch in look and feel, well worth the purchase price. Thank you so much!
