Welcome to I/O Fitness (formerly CrossFit I/O, an official CrossFit Affiliate since 2016).
We are the first and only functional fitness gym located in Cleveland Heights. 
We are a diverse community of everyday people who strive to be better than we were yesterday. 
We are inclusive and supportive. We consider ourselves a family.
One which is free of judgement, and open and encouraging to all.
We are like-minded in our health and fitness. That's what makes us strong.
No matter who you are, how you're built, what you believe, or how you love,
we are proud of our community.
Together our sweat glistens all the same.
We Make Every Human Better.
We are I/O Fitness


 We Are Constantly Varied

In short, the majority of our programming is not a routine. Our goal is to prepare you for every and any imaginable fitness task. What we do varies from day to day, week to week, and month to month. If you get bored at a gym, it’s because a routine gets boring, that won’t apply here.

We Use Functional Movements

These can be described as a movement that involves more than one joint, and has a core to extremity movement pattern. In short, we don’t use machines, and we rarely isolate. Functional movements are not mastered overnight. Our coaches are constantly working with our members to help them improve their technique, no different than any other elite athlete has a coach to help them with their sport. 

We Perform At High Intensity

It’s about working hard. "Hard working" is a necessary character trait for all our athletes; it’s how we get results. Our coaches and our group training environment will certainly help you in that department, as will the community of people around you. And this is where we might lose some people, because if hard working is not in your list of character traits, you will not like what we do. We like to think that nothing worth having comes easy, and what you accomplish here will do more than make you a better athlete, it will make you a better human!
