I don't think so. Such reluctance is understandable.
Most workers use their lunchtime to socialize, relax, shop, or read.
Squandering that valuable time on the Stairmaster will strike some as an unappealing option. Complicating things even further are such nagging issues as sweat and the post-workout shower. But if responsibilities like work and caring for the family occupy the better part of your day, consider the benefits of a midday workout. Lunchtime workouts can counter this time-honored excuse. A greater storehouse of energy makes exercise easier and more enjoyable, providing incentive for future workouts.
