If you can’t get enough of Zac Efron’s biceps in the trailer for The Lucky One, here’s something else to tide you over until the Nicholas Sparks adaptation hits theaters on April 20: Efron’s left bicep on the May cover of Men’s Health. You’re welcome. Should you want to read the article, as well as ogle more sexy armed forces-inspired photos, you’ll find out just how he got into Marine shape with the help of trainer Logan Hood, a former Navy SEAL. By the time the film wrapped, Efron had gained 18½ pounds. For four months, five days a week, he began his day at 5:30 a.m. with “a shake and, you know, an eight-egg omelet” before working out for an hour on a full stomach. He’d eat six to eight times a day, with shakes between meals, to reach his daily target of 3,500 calories. Read tips from his trainer here.

Other essential info, from the cover story: “He’s been having dinner lately with Warren Beatty, a master with wisdom to share.” (Again, you’re welcome.)
