With the price of gym memberships rising, we're all looking for a less expensive way to burn calories and stay fit. Instead of putting your foot down and refusing to pay, put that foot to good use and practice Parkour —your fitness props become the things around you like benches, railings, trees, walls, stairs, and fences.

It takes trust in yourself and a fearlessness to be really good at this sport. Although a sane person may not find this appealing, this video below may inspire you to get started so read more.
