Port St. Lucie’s #1 strength gym

Since 2017 we have welcomed everyone— whether you're an internationally ranked athlete or trying to lose 100 lbs to play with your kids. The gym was built on the idea that everyone deserves to be the strongest and healthiest version of themselves, and to do that, you need a welcoming, judgment-free space (minus the pizza) that pushes you to be your best.

I normally hate going to the gym but Iron Knight isn’t really a gym. It’s a bunch of people who become family who enjoy helping each other look and feel better! I’ve only been going for a few months but I already see and feel the results. My coach is amazing and we were paired perfectly! If you’re looking to get serious about yourself and your health journey, Iron Knight is the perfect place to start!
