Home of the Original Iron Basement, our gym combines serious training space with a welcoming environment for members of most ages and fitness levels.
No contracts. No hidden fees. No gimmicks.
Just a gym that works as hard as you do.
Welcome to AlterEgo Fitness: the complete opposite of the corporate gym experience.
The largest selection of serious training equipment in the area, including unique machines you won’t find elsewhere, and the knowledge to help you use them right.
A Gym for Real People
AlterEgo Fitness is built for people who want to train, not pose.
We welcome beginners to seasoned lifters. If you're new, we'll help you learn the equipment and get comfortable. If you're experienced, you'll have the space and tools to train the way you want.
Gym membership is not included/ required for some classes. Please contact Instructor for details.
