I'll take that dare is a YouTube series where Lindsay goes out and tries a different activity. Recently they did a parkour edition with the traceurs of NY Parkour. Check out the video and when you're done check out the nice things Lindsay had to say by clicking read more...
Behind the scenes of the video, I have to tell you that I was surprised by how nice and normal the Parkour "crew" was- Watching their videos, I guess I was expecting them to be a closed group of cooler-than-me young people.
I was wrong.
They were warm, friendly, open to newcomers, and their classes, particularly the beginners' classes, include people of all ages and backgrounds. Kids in particular are picking up Parkour- and often, their parents are joining them in classes. I think that's very cool.
Whether you have a kid with you or not, the conditioning alone is worth trying out - It was INTENSE - and I love the Parkour philosophy of exercising with a specific goal in mind (i.e., I want to be able to leap farther/jump higher/run faster), as opposed to just "working out" with no real plan. I totally get that.
