Shake off slothful companions and other motivation-sapping pitfalls with tips from fitness expert Michael Bracko
 DELAY DINNER: Business trip or vacation, there's usually a lull before the evening meal. If possible, push dinner back to at least 7 p.m. to extend this window of opportunity.
 GO STEALTH: Never tell anyone you're going to go exercise. "It makes them feel bad that they aren't doing the same," says Bracko. "They'll harangue you to have a drink at the bar instead. I tell people I need to go check my e-mail or make a call."
 IMPROVISE OBSTACLE COURSES: Holed up at a convention center? In most buildings you can go for a run after everyone leaves. It's safe, and you'll never miss a workout due to bad weather. Plus, with a maze of staircases, monstrous hallways, and random chairs to jump off or over, it's like a businessman's jungle gym.
 NEVER GIVE UP: If all else fails, do five minutes of squat thrusts/push-ups. Squat, plant your hands, kick legs back, do a push-up, return to squat position, and stand up.
