Are you Ready to get Healthy and Fit?

We can help! Get Started

Our Goal

We are committed to helping people get started on their Fitness Journey. At CrossFit Kinnick Ontario, our Trainers help members of all ages and abilities reach their health and fitness goals.

We’ve helped hundreds of members lose weight, gain strength, and improve their health markers (blood pressure, blood sugar, cholesterol, etc) through lifestyle changes.

The vast majority of our members come to us out of shape, with very little prior gym experience. We are able to safely provide them with a solid foundation of basic movement patterns and strength by gradually introducing them to more challenging movements and workouts. This helps set the stage for years of physical improvement and health.

Many people come to us a little intimidated by CrossFit (usually after seeing it on ESPN or CBS Sports). But after they see our 60 and 70 year old members doing the workouts they quickly realize that they can do it too. That’s the beauty of CrossFit. We adjust all the workouts for each member so that they are challenging but doable. We never ask you to do things you can’t do, or that are beyond your current ability.

Come in and talk to a Trainer and we’ll get you started on your own Fitness Journey!
