When it comes to crushing the Marine Corps Physical Fitness Test, it’s all about the pull-ups. Sure, if you can lope along like a gazelle and snag an 18-minute three-mile-run, you’re well on your way to a perfect score, but you still need to max out on pull-ups. With the Marine Corps’ new PFT changes, men between 21 and 35 will need 23 pull-ups for a perfect score, while women of the same age will need between nine or 10.
Marine Corps Sgt. Michael Eckert is a pull-up machine. Stationed in Iwakuni, Japan, the 26-year-old holds the Guinness World Record for most no kip pull-ups with hands pronated on the bar in 60 seconds. But if you’re looking for some pull-up inspiration you should really check out his Instagram. Using the social media platform, Eckert archives workout routines, fitness pro-tips, and some really badass pull-up stunts.
Not all heroes wear capes, and not all athletes play sports. Some of them, like retired U.S. Marine officer George Hood just exercise very, very intensely. In 2015, Hood set the Guinness World Record for “planking,” a competitive exercise that entails using one’s forearms and toes to keep the legs and torso elevated several inches above the ground, straight like a wooden plank.
