Tone Your Arms in the Ladies' Room
Push-ups are a great way to sneak fitness into the workday. The only equipment they require is a flat surface—and it doesn't need to be horizontal. Archer suggests doing push-ups with your hands on the wall instead of on the floor, which makes them easier. A bathroom stall is a good choice (the end stalls usually have more room, as well as a sturdy floor-to-ceiling side wall). "Many female clients have told me that they've seen noticeable differences in their arms after doing daily push-ups against a wall or on the edge of a sink," Archer says. She advises doing 10 to 15 a day.
As a reminder, always consult your doctor for medical advice and treatment before starting any program.
