Our company has an on-site gym where many of my staff members work out, as do other executives. I feel self-conscious exercising there, though, particularly since I’m not in the best shape. Do you think working out where you work undermines a boss’s image and authority?

What are we talking about here? Are you a potential contestant for “The Biggest Loser”? Do you grunt like a linebacker when you bench-press 15 pounds, or cry for your mama during a treadmill warm-up?

You always want to be mindful of your image at work. So if you’re in really bad shape and uncomfortable working out among colleagues, then don’t. Start at your local gym, and once your condition improves perhaps you’ll feel better about moving to the office sweatshop. There are potential benefits of working out at work, including the camaraderie and potential to interact with people you might not otherwise meet. And connecting with colleagues outside work can strengthen relationships.

Having said that, there are rules to heed if you’re going to get physical at work. Don’t flex or admire yourself in the mirror. Don’t wear an “outfit” — if you match from headband to wristbands to toes (or if you even wear wristbands), you’re inviting mockery. Nothing too revealing or shape-defining. And for God’s sake, don’t douse yourself with water and scream, “I feel the burn!” with each ab crunch. Follow?
