Who trains here

Bodybuilders train here.
So does everyone else.

George built TNT around championship standards, then opened the doors to everybody. First-timers, parents, competitors, people rebuilding after injury. Same coaching. Same intensity dialed to you.

The legacy
George
Turmon
IFBB Professional Bodybuilder · Mr. South Carolina 1990
"His legacy doesn't hang on a wall. It lives in every athlete who trains here."

From the hardwood at Georgia State to the IFBB Pro stage, George spent 35 years mastering human transformation. He earned his Pro Card at the 2003 Masters Nationals, one year after a hip replacement, then placed 5th at the Masters Olympia a month later. The crowd booed. They believed he deserved higher.

He opened TNT to pass that knowledge forward. Today his sons Jonathan, Jordan and Joshua carry the fire.
