“Such a great gym! They've recently expanded and it looks so good! Lots of equipment and space, it's not crowded like commercial gyms are, and it's very clean and well-kept. Sean is an amazing trainer - motivating, educated, and super friendly. 10/10 recommend Stallion Arena :)”
Lauren V. Member“The best gym experience I've ever had. I have struggled with weight loss my entire life. When I met Sean at Stallion he coached me in a way that worked best for me. In 6 months I lost 35 lbs. Sean is an amazing trainer. Knowledge, professional and friendly. The staff and the gym members are great. Such a great vibe.”
