The newest high intensity strength and conditioning facility in Northeast Tenn. No state of the art machines, just hard work, know-how, and the right mindset to exceed the highest goals.Disclaimer: 423 S&C is NOT for everyone. What we do is not for the faint of heart or weak minded. There is no easy way to achieve victory. You get what you give, and if you give your all - we promise results! If not, it may suit you to go elsewhere. Thank you.
