100% Recommend!

“Never did I think I would look forward to working out. Never did I believe I could do it. But I am so proud of myself. Between the coaching, facility, equipment, and the people. Since day one I’ve met some very cool and encouraging people who are already cheering me on. Don’t be scared – don’t think you can’t do it – don’t think it’s too hard. This gym will welcome you with open arms and help you find strength in yourself you never thought you had.”

~ Deb D.

Fantastic Coaches

“I can’t say enough good things about Crossfit Onus. I have been working out regularly here for 3 years. The coaches are fantastic, they work with everyone to teach correct form which is so important. The classes are an hour, but you will leave with nothing left in the tank! The best part is it’s different each day. You will never get bored. The absolute best thing though is the people. Everyone is so encouraging and uplifting. We truly have something special here.””
