John Hardtke

Trainer John Hardtke works primarily at Fitness Together in Whitefish Bay, WI. However, he lives in Whitefish Bay, so sometimes you'll see him at our gym doing his own workouts or working with his private clients. You'll notice John as being one of the only people strong enough in our gym to justify the use of chalk on the back of his t-shirt to help keep the bar in place.
