What is Slak CLE all about and why should you train with us?

Slak CLE is a human performance gym that primarily uses balance training equipment to target areas of the brain that deal with movement, coordination and overall brain and body performance.

What we know.

We have found, through scientific research and first hand experience, that balance training increases your ability to not only function physically better but mentally as well.

Our experience.

Dr. Will, Co-owner of Slak, first began slacklining in 2018 to help balance his pelvic muscles after a debilitating back injury that left him in pain for over 5 months.

The results.

After utilizing the slackline almost daily for about a 4 weeks, the symptoms of his back pain went away.  After a few more weeks, he began to notice his athletic ability was increasing and he also began to notice that his thoughts and behavior began to change as well.


This led Dr. Will down the scientific research rabbit hole of balance training that uncovered the positive effects of balance training on the physical body as well as the brain.

What we found.

What he found was amazing, balance training actually caused neurological and physical changes in those who regularly challenged their balance system.


There are MRI findings of study groups who balanced trained for 4-6 weeks and showed an increase in areas of the brain that deal with memory and cognition as well as a reduction in the areas of the brain that deal with stress.

Science says...

The science says that balance training increases physical ability, coordination, muscle activation, joint stabilization, strength and another fascinating discovery is that it also calmed the brain which correlated with a decrease in stress, anxiety, depression and also increased brain function that involved memory, learning and reasoning abilities.

The discovery.

This discovery astounded us and we believed, because of the science and our own experience, that balance training was the key in developing a better brain and in turn a better body.

We knew.

We immediately knew that everyone should be balance training in some capacity on a regular basis and that that is why Slak was born.

Balance at the core.

At Slak CLE balance training is at the core of everything we do.

How we do it.

We utilize a special device called a "slackline" that challenges your balance beyond any device currently being used by anyone out there today.

Becoming dynamic.

We also utilize other forms of training to completely train the body.  We incorporate speed, agility, strength and coordination techniques and devices to effectively coordinate and condition the body while also increasing overall brain and physical health.

The result.

The results are a more balanced and dynamic brain and body that is capable of doing far more physically and mentally than a "non-balanced" brain and body.


How else do we help?

At Slak we take an all round "360" approach to performance.  We stress the importance of not only physical health but also mindset and nutrition as well.  Dr. Will is a Chiropractor who specializes Chiropractic and Nutrition.  We also have Mindset Coaching available.

By combining all 3 areas of success, Physical, Mental and Nutrition, you can certainly reach your Optimal Performance.

What ATHLETES Are Saying!

SLAK CLE came to our goaltending camp this past weekend to introduce our goalies to slak training. Our goalies loved it, and the SLAK CLE staff was great with the kids. Not only is the workout challenging, it is unique, and tons of fun! Highly recommend!
--Sebastian Ragno-- ETM Goal-tending Coach
Kathryn Connors did a great job of training me for my first slack line. She really understands and can see what her clients abilities are and she pushed and believed in them. I did better than I thought I would, with her knowledge and help. Thanks Kathryn I will definitely recommend you!!!
--Kimberly Davis--
"I started training with Slak CLE about 2 months ago and the results I've seen have been nothing short of amazing. Being a 6'6" goalie in hockey, coordination, control, and balance were not the strongest parts of my game. With Jason, I worked on really slowing things down and moving in a calm, controlled manner. My balance obviously improved a lot, along with my coordination and control, but there were also unexpected changes to my game. The biggest of these was my focus. Training on the SLAK lines makes focusing on the puck a lot easier. All of these improvements have translated to more saves, and better play on my part."

The key to muscle coordination starts in the brain.  Our unique approach puts balance at the top and is incorporated into everything we do.

Speed and Reaction time is paramount in athletics and in life.  We use techniques to train the brain as well as the body to increase speed performance.

The ability to move around or over an obstacle depends on your brains ability control your muscles to navigate your surroundings.  We have hundreds of agility combinations.



Strength is dependent upon muscle/joint stabilization.  At Slak we focus on the intrinsic muscles to create dynamic functional strength.

Coordination is your brains ability to move your body through space smoothly and precisely.  We use techniques to enhance that ability.
