Mark Wahlberg shows off his tickets to the gun show on the August cover of Men's Fitness.

Of his workout regime, the 39-year-old tells the mag "When I first started training, I was trying to lift the gym, as much weight as possible, all day, every day.”

Though he's fixed his ways with the help of a trainer, he adds "I worked so hard to get in shape, I might as well maintain it.”

Wahlberg also talks about family life and how it affects the roles he takes in the issue, which is on newsstands now.
