I enjoy every class I have with Alexis. I know she is going to push me to my full potential and I love that! The workouts are hard but I always feel great afterwards and more motivated for the next class.

I love how Rebecca show you the proper way to hold the bar for hangs, snatches, choosing the proper weights with building. Great training skills for sure. She makes you feel comfortable. 💪🏽💕

Great atmosphere! Starting my fitness journey again, it was great to see all the modifications available for starters so that we could complete the WOD and still be challenged. 💪🏼

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!
