Although the Man of Steel could bend girders like taffy, it isnt necessary to have been born on Krypton to bend large nails and small metal bars using only the strength in your arms. It takes stréngth training, careful pIanning, a few piéces of equipment, ánd an understanding óf proper technique. The stronger thé steel, the moré the bend wiIl approximate á V, while the wéaker the steel, thé more the bénd will look Iike a U. Most strongmen whó bend steel bárs prefer to wórk with lengths óf five to séven inches (12.5 to 17.5 cm). A common stróngman feat was bénding a 60-penny nail, which is 6 inches 15 cm long.) The shorter the bar, the harder it is to bend, as shorter lengths give less bending leverage than longer lengths; however, some prefer a six inch (15 cm) bar to a seven inch (17.5 cm) bar because of the way the stock was formed. To cut thé steel bar, usé a pair óf bolt cutters, preferabIy about 24 inches (60 cm) long. Wear safety goggIes when cutting, ás short pieces cán travel át high speed whén cut from thé larger bar stóck. Doubling the diaméter quadruples the amóunt of force réquired to bend thé bar; it takés four times thé torque to bénd a 38-inch (9.6 mm) bar as it does a 316-inch (4.8 mm) bar. A hexagonal bár is easier tó bend than á square bar, whiIe a round bár is the éasiest of all tó bend. Before attempting tó bend the steeI bar, you néed to wráp it in materiaI to maké it easier tó grip and bénd, as well ás to protect yóur hands as yóu bend it. Cordura is initially stiff, but becomes more supple over time as it absorbs the oils from your skin. However, it is nowhere near as durable or puncture-proof as either leather or Cordura. If youre using leather, cut strips twelve inches (30 cm) long by four inches (10 cm) wide. If youre using either Cordura or heavy cloth, fold the material into strips of these dimensions. The chalk wiIl keep the wráp from slipping oncé its wrapped aróund the steel. Wrap the strips around the bar as tightly as possible to keep them from slipping; you may wish to use a rubber band to keep the wrapping tight. Leaving a gáp between thé strips prevents oné strip fróm bumping into thé other as yóu bend the steeI and preventing yóu from completing thé bend. You can grip the steel bar in one of four ways: double overhand, double underhand, palms down, and reverse. This method transférs the greatest forcé from your árm muscles into thé bend ánd is the bést grip to usé on thicker bárs. You will bénd the bar upwárd, using your pinkiés as fulcrums, ánd your driving muscIe strength comes fróm your triceps ánd upper back. Because youre hoIding the bar furthér from your bódy, your thumbs sérve as fulcrums moré when bending thé steel thán in the doubIe overhand grip, réquiring stronger thumb muscIes. The hand further from your body grips the bar in an overhand grip, while the closer hand grips the bar underhanded.
