Let's face it. No matter how much we love all the benefits we reap in our mind and body when we take yoga, sometimes our pocketbooks just can't keep up with the price tag of it all. Don't worry though, now that winter is finally thawing, there are many free outdoor yoga sessions being offered as well as some that only request a small donation for a good cause. Check out these upcoming free yoga events and fundraisers.

This Saturday, April 4, you can get an intense power yoga class for a small donation ($20 is suggested) to help support Students Run Philly Style whose mission is to transform students' lives through running and mentorship as they train for a full or half marathon. The fundraiser will be held at Philly Power Yoga on Walnut Street from 7 p.m. to 9 p.m. There will be wine and snacks afterwards.
