Gripz Goes Green

Environmentally-friendly changes in 2019

We might be an indoor business, but we love the outdoors! We want to help ensure that generations of kids and adults can enjoy the playgrounds and ourdoor obstacles courses that help give us our start.To learn more about climate change, click here.


To learn about some things that you can do:


100% Renewable Electricity

All of Gripz Gym is now powered by renewable energy! Through DTE's MIGreenPower program, 100% of our energy comes from renewable sources.

Custom Water Bottles

Single-use plastic, such as found in disposable water and Gatorade bottles have a double impact on the environment. The carbon dioxide used to make the bottles is released into the atmosphere and the water bottle most likely will end up in a landfill.
We are selling the Gripz Water Bottles for $10. But, we are giving you the opportunity to save some money, too! Every time you bring your Gripz Bottle into the gym, you'll earn $1 credit toward class packages and open gym memberships. Limit $5 credit/month per household.
To help reduce our waste, we will also stop selling water and Gatorade in the gym.

Bottle-Filling Water Fountain

Our new drinking fountain includes a bottle-filling station so you can fill up your new Gripz Water Bottle with some nice cold and refreshing water.

Gym Recycling

We will continue to offer recycling within the gym. Toss your water bottles or paper goods into the recycle bin instead of the trash and we'll make sure to get them over to a recycling center.

Hand Dryers

Both bathrooms have been outfitted with electric hand dryers to reduce paper waste.

2019 Prices

Our gym rent is going up, so to continue to provide the same great coaching, service and equipment, we will be raising prices on a few of our programs. Even with the price increases, Gripz Gym still offers the best ninja experience for the lowest price in Southeast Michigan! All class and kids open gym packages can be shared within the same household.
