The Mechanics of the Pull-Up (and Why Women Can Absolutely Do Them) | Guest Blog As a former rock climbing instructor, I have seen many contorted struggles to raise a chin over a bar. The pull-up for many is a sort of “test piece” of fitness—an indicator of athletic prowess—that is a cornerstone of a good workout (or a good showing-off). Most either never try a pull-up after they leave high school gym class, or fail, but many succeed, especially women. Long-time rock climber Sarah Brengosz pulls hard. You can do yoga all day, you can run or bike or swim, but a pull-up will still be hard. The equation below describes the struggle: A few things pop right out of the equation. A lanky individual myself, I happen to have a decent balance between mass and arm length. First, muscle men tend to flounder with the pull-up because of their mass. Second, arm length matters. Lastly, gravity is important for the pull-up. So there is a trade-off. Through this whole discussion, I’d bet that your mental image was of a man doing a pull-up; I want to change that.

Visiting 10 of the Most Interesting Abandoned Places on Earth Travelers looking for a getaway from the normal getaway should skip the sandy beaches to walk amid silent relics in Namibia, Chernobyl or an abandoned California gold mining town. These empty places may look like Scooby Doo set pieces, but they hold important clues to bigger mysteries about both the past and the future; the creep of urban decay and the necessity of memorializing tragedy. Sometimes history lives alone. We bring you 10 modern ghost cities where you can choose your own adventure, exploring what once was and what could have been. Hashima Island, Japan After spending a little less than a century as a bustling coal mining facility, Hashima Island became known as "Ghost Island" when demand for petroleum outstripped demand for coal in the 1960's and the 5,000 Mitsubishi-employed islanders began a mass exodus. Hashima Island was officially re-opened for tourists in April 2009. 1 of 10 Photos

Long-distance running and evolution: Why humans can outrun horses but can’t jump higher than cats By Chris McGrath/Getty Images. At first glance the annual Man vs. Horse Marathon, set for June 9 in Wales, seems like a joke sport brought to us by the same brilliant minds behind dwarf tossing and gravy wrestling. It was, after all, the product of a pints-fueled debate in a Welsh pub, and for years its official starter was rock musician Screaming Lord Sutch, founder of the Official Monster Raving Loony Party. But the jokiness is misleading: When viewed through science’s clarifying lens, the funny marathon is one of the few sports that isn’t a joke. Hear me out, sports fans—I'm a basketball nut myself, and so the joke is as much on me as anyone. There's no denying it—our kind started substituting brains for brawn long ago, and it shows: We can't begin to compete with animals when it comes to the raw ingredients of athletic prowess. The Wales marathon has helped demonstrate that. Elite human runners, however, can sustain speeds up to 6.5 meters per second. But how did we get this way?

The First Zombie-Proof House Somehow, ritual drunk-conversation concerning team captains for the apocalypse has become a major part of the lives of 20-somethings. Having been matured in the Grandaddy-crowned masterpiece film (put “A.M. 180” on and forget that you have a job) 28 Days Later and the best-selling Zombie Survival Guide, we’re all a little too ready to deal with the 2012 zombie apocalypse of our dreams. “The Safe House,” designed by KWK Promes, starts to get eerily close to something I could work with, if say 200 bludgeoned members of the undead army came over to eat their way into borrowing some sugar. “The most essential item for our clients was acquiring the feeling of maximum security,” begins the designers’ website in the summary of the structure. Who wouldn’t feel safe in a concrete rectangle that folds in upon itself to become completely sealed? Even the windows are covered with a slab of concrete when the structure is on nap time.

The rise of barefoot running Sony Nextep Computer Concept for 2020 by Hiromi Kiriki & Yanko Design In 2020 We Can Wear Sony Computers On Our Wrist Our present need for internet connectivity is so profound that secondary devices like the Nextep Computer are bound to happen. Developed to be worn as a bracelet, this computer concept is constructed out of a flexible OLED touchscreen.

Barefoot running vs running shoes Two Suns? Twin Stars Could Be Visible From Earth By 2012 By Dean Praetorius | HuffingtonPost.com Earth could be getting a second sun, at least temporarily. Dr. Brad Carter, Senior Lecturer of Physics at the University of Southern Queensland, outlined the scenario to news.com.au. Betelgeuse, one of the night sky’s brightest stars, is losing mass, indicating it is collapsing. It could run out of fuel and go super-nova at any time. When that happens, for at least a few weeks, we’d see a second sun, Carter says. The Star Wars-esque scenario could happen by 2012, Carter says... or it could take longer. But doomsday sayers should be careful about speculation on this one. In fact, a neutrino shower could be beneficial to Earth. UPDATE: To clarify, the news.com.au article does not say a neutrino shower could be beneficial to Earth, but implies a supernova could be beneficial, stating, "Far from being a sign of the apocalypse, according to Dr Carter the supernova will provide Earth with elements necessary for survival and continuity."
