THE THUNDER STORY
REAL IRON.
REAL PEOPLE.
Thunder Gym isn't a corporate fitness chain. We are Miami’s home for old-school strength and modern performance. Whether you're hitting the irons, stacking plates on our Hammer Strength machines, or pushing the sled on the turf, you belong here.
We pride ourselves on a "hardcore training, family atmosphere" vibe. Grab a cafecito, meet the crew, and get to work. No contracts, no nonsense—just gains.
