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.
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 rise of barefoot running Barefoot running vs running shoes Debunking the 3 Biggest Exercise Myths Loss of More than 2 Percent of Your Body Weight During Exercise Degrades Performance This debate, popular among exercise gurus and professional trainers, centers on how much water weight an athlete can lose without sacrificing performance. Lab tests have suggested that a body-weight loss of more than 2 percent impairs athletic performance. This information has become accepted. Introducing the most powerful Lamborghini ever: the Veneno LP740-4 (pics from all sides) We have known for quite some time now that Lamborghini was planning to introduce a production model that would be the most powerful supercar that they have ever sold to help celebrate the company’s 50th birthday but thanks to information leaked on the internet last night, we know that this historic car is the Lamborghini Veneno LP740-4. Details are limited on the Veneno but thanks to the bit of information included in the early leaked magazine image – we know the details that matter most to both buyers and dreamers. As expected, the Lamborghini Veneno LP740-4 is powered by the same 6.5L V12 that is found in the current Lamborghini Aventador LP700-4 but as the name would denote (for those familiar with Lamborghini naming schemes), the Veneno offers a touch more power. While the front end of the Lamborghini Veneno LP740-4 is strikingly unique, the back end is obviously a little bit Sesto Elemento and a little bit thoroughbred race car.
Let's Get Physical: The Psychology of Effective Workout Music “I dare them to find the iPod on me,” Richie Sais told the New York Times in 2007, when he was preparing to run the Marine Corps Marathon. USA Track & Field, the national governing body for distance racing, had just decided to ban athletes from using portable music players in order "to ensure safety and to prevent runners from having a competitive edge." Rais resolved to hide his iPod shuffle under his shirt. Many fellow runners protested the new rule, which remains in effect today in an amended form: It now applies only to people vying for awards and money. For some athletes and for many people who run, jog, cycle, lift weights and otherwise exercise, music is not superfluous—it is essential to peak performance and a satisfying workout. Selecting the most effective workout music is not as simple as queuing up a series of fast, high-energy songs. When running on a treadmill, however, most people seem to favor music around 160 bpm.
Daredevil dies in rope swing stunt popularized by YouTube SALT LAKE CITY (AP) — A 22-year-old Utah man was killed trying to swing through the opening of a 110-foot-tall sandstone arch in a stunt made so popular on YouTube that state authorities recently banned the daredevil activity by commercial outfitters. Kyle Lee Stocking, of West Jordan, left too much slack in the rope he was using, and it sent him crashing into the sandstone base of Corona Arch near Moab, Grand County sheriff's officials said. He died Sunday afternoon. Viral videos have bolstered the activity, which involves swinging wildly from ropes through arch and canyon openings. "Pendulum" swinging is a relatively new form of recreation in Utah's canyon lands, which see plenty of injuries and deaths from rock climbing and BASE jumping, which involves leaping from a fixed object with a parachute. "People aren't accepting nature for what it is. Stocking was with a group of five friends authorities didn't identify. Stocking's rope and harness didn't fail.
Everest Maxed Out An hour above high camp on the Southeast Ridge of Everest, Panuru Sherpa and I passed the first body. The dead climber was on his side, as if napping in the snow, his head half covered by the hood of his parka, goose down blowing from holes torn in his insulated pants. Ten minutes later we stepped around another body, her torso shrouded in a Canadian flag, an abandoned oxygen bottle holding down the flapping fabric. Trudging nose to butt up the ropes that had been fixed to the steep slope, Panuru and I were wedged between strangers above us and below us. Now, bumper to bumper at 27,000 feet, we were forced to move at exactly the same speed as everyone else, regardless of strength or ability. Panuru, the lead Sherpa of our team, and I unclipped from the lines, swerved out into open ice, and began soloing—for experienced mountaineers, a safer option. TAMING THE MOUNTAINThe success rate of climbers has more than tripled since 1990, largely due to more guides and better gear.
