Many people woke up Saturday morning to hit the gym, but this time it was all for a good cause.

The annual Spin4Kids fitness fundraising event at Saskatoon's GoodLife Fitness aims to raise money in support of physical activity programs for kids.

Last year, the one-day fitness event raised just over $30,000 in Saskatoon for the GoodLife Kids foundation. All of the money goes to support local grants for physical education programs across the country.

Since 2015, the Saskatoon Public School Division and Autism Services of Saskatoon received three grants to help cover the cost of some physical education programs.

This year, about 200 participants are involved and hope to raise $45,000 in Saskatoon.

Assistant general manager of Saskatoon's GoodLife Fitness, Stevie Simon, said it's important to get kids active at a young age.

"It's so important to help them build those habits, and set that foundation for them," he said.

"They're going to learn to love Fitness and be physically active at a young age and hopefully we can maintain that through the rest of their life."

The event runs until 4 p.m. Saturday.
