Park Benches Can Be Fun

We captured video footage of some random dude jumping over a park bench earlier today.
Pay attention to the three methods he uses to get over the bench. We think they're rather Parkourish.
In Jump Sequence 1, the random dude uses a combination of arms and legs to get over the bench. This requires a little technique, not much timing, and is the least athletic of the three jumps.
In Jump Sequence 2, the random dude again uses a combination of arms and legs, but this time only uses his arms to get past the last part of the bench and propel himself forward an extra few inches--just enough to clear the bench. This requires some technique, a good deal of timing, and is slightly more athletic than the prior jump.
In Jump Sequence 3, the random dude uses no arms at all; he simply hurdles over the bench. This requires some technique (only a basic understanding of launch angle at takeoff), a good deal of timing, and is the most athletic of the three jump sequences.
CrossFit Santa Cruz 2007-lb Challenge
Check out the following post on the CrossFit Santa Cruz site:
http://www.crossfitsantacruz.com/crossfit_santa_cruz/2007/01/clean_slate.html
Max attempted this earlier today and clocked in at 1:21. He power snatched 67 lbs for 30 reps.
Give it a try and play with different rep/weight schemes. Multiple attempts at this challenge using different schemes will give you a nice understanding of the difference between muscular failure, cardiorespiratory failure, and systemic failure (muscular failure and cardiorespiratory failure combined, or at least in close proximity to one another).
Post your strategy and results for the 2007-lb challenge to Comments.

hey Random Dude,
Looks awesome! I know the last one is the most athletic, but I think the most elegant jump is the second...any chance we can get a group together and you can walk us though it? Anyone up for another war wound?

did this morning. yes, I actually came to a morning class. my boss is gone, so I can come in late.
72# x 28 power snatch. 1:16.

Mike, it looks as though the first jump was smoother than the second as far as maintaining your speed and stride after the bench was cleared, even though it's "less athletic" and requires less skill. Thoughts?

Ok, which woman will be the first at CFO to accomplish the 2007 lb challenge?!
I'd be up for trying some bench jumping or other if we got "random guy" back for a demo:)
Also, I would like to get an accurate calculation for my body fat percentage. Are the instructions for this in one of the CF journals? Isn't it a lot of measurements? If it's kind of complicated for first-timers, can we talk about or do it after Saturday's workout? Thanks!

I did the 2007-lb challenge this morning before my workout. I knew this would almost certainly be slower, but for comparison I did 19 x 105# C&J (power clean & push jerk) + 1 x 15# one-arm DB snatch. It took me 3:32, because I couldn't do the C&J in an unbroken set. Even if I could have, I still think it would have been slower, as each rep took 4-5 seconds (at least). I may try this again with different weights and schemes to see what happens. I think some version of power snatching pretty much has to be fastest.

Jonathan,
I don't disagree with anything you said. The transition is smoother and if I were moving right into another skill immediately following the bench jump, Method 1 would be the way to go.
But if the point is to get over the bench as quickly as possible, Method 3 takes the cake.
Be that as it may, the three jumps range from least athletic to most athletic, not dissimilar to the range of athleticism displayed in the shoulder press, push press, and push jerk. And that was really the point of the video.
Good observations!

There are only two ways to get an accurate bodyfat reading. The first is hydrostatic weighing, the second is the http://www.bodpod.com bodpod. It is over $100.00 to get a reading with either method. The "Athletic" range for women is usually considered to be 14-18% for women with anything under 30% considered healthy. Ann you are solidly in the athletic range and I would not change a thing bodyfat-wise. In fact you could stand to put on 10 pounds, perhaps 8 pounds of muscle and two pounds of fat (if you put on muscle without gaining and fat your bodyfat percentage will go down).
You can get a non-accurate reading using our bodyfat scale at the gym.

Max, how do you find out your percentage?
Posted by: Ann Kelly at January 4, 2007 1:30 PM
Ann, I don't understand the question.
Posted by: Max Lewin at January 4, 2007 2:56 PM
ann, I will go with you to get the body fat thing done if we can figure out how.
mike... you are my new hero, are you going to come to a tumbling class with me?
Posted by: annie Vought at January 4, 2007 3:12 PM
Max, I meant how do you personally get yours checked? Do you go in the bod pod?
Annie, I'd like to consider it, but it depends how much it costs. Now would be a good time to get one done though.
Posted by: Ann Kelly at January 4, 2007 3:42 PM
Ann:
I did the bodpod at Columbia University in NYC. You can find the nearest one through their website.
Posted by: Max Lewin at January 4, 2007 4:11 PM
Also I have a high-end Tania bodyfat measuring scale (around $200.00). The cheap ones don't work. It is somewhat accurate (and presently depressing).

Oakland doesn't have park benches, or parks, that clean. I think there were special effects involved.
Posted by: Joanne at January 4, 2007 4:29 PM
LOL, Joanne! You're too observant.
You are correct. It was shot somewhere else other than Oakland (although I've done the same moves in Oakland parks).
I'll leave it up to your imagination and judgment whether or not special effects are involved.

that video looks like it was shot in an architect's nightmare: the subdivision! dun, dun dun! those things represent all that is wrong with the world. they always remind me of that part in the X-Files movie when they build that playground over the hole where those kids fell and got infected with the black oil. but i digress...
Posted by: Jonathan at January 4, 2007 4:56 PM
Oh my god! I am obsessed! You should check out http://www.parkour-videos.com/speed-air-man-david-belle It's incredible. Your moves are just as cool as his Mike! :)

Ann, i will do the 2007 thing with you. This weekend. Or we can do it psychicly together. Also candance have you seen the new 007 movie..
Posted by: annie Vought at January 4, 2007 6:30 PM
P.S. I love the quote! Scott and I have an agreement that I can leave him for Barak Obama if he will have me.
Posted by: annie Vought at January 4, 2007 6:48 PM
I just went out with my roommate parkouring. We went to a jungle gym surrounded by a miniature stone hinge and jumped across the entire structure in one fell swoop. Ok. Maybe not. But it seemed like we could have if we really wanted to. I am now prepared to escape any situation! And, of course, lift 2007 pounds in less than 30 seconds. What do you say to that???
Oh. One more thing. Annie, we may have to fight over Barak - although I alternate between wanting to date him and wanting to be him. It's a complicated inner struggle I have with myself.
Posted by: Candace Hamilton at January 4, 2007 7:27 PM
Candace can we see a picture of the "miniature stone hinge"? Sounds like a stone age hamster cage component.

"I just have one question. Are we doing Stonehenge tonight?"
good call Tim.
"Making a big deal out of it would have been a good idea."
Posted by: Jonathan at January 4, 2007 11:20 PM
Further to Ann's question about body fat, there's an article in this month's CF Journal about why it's not something you should be worrying about a whole lot.
Posted by: Sam L at January 5, 2007 7:10 PM
Annie,
Dr. Sears has the formula for you to find out your body fat percentage in Appendix B of his book The Zone, page 213. It is at least cheap and good enough.
I am surprised none of our CFO experts knew this. Is another reading of the book in order coaches?
