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.
