The American H e a r t Association provides these tips
to increase activity levels at your worksite:

Brainstorm project ideas with a co-worker while taking a walk. 

Stand while talking on the telephone. 

Walk down the hall to speak with someone rather than using the telephone. 

Take the stairs instead of the elevator. Or get off a few floors early and take the stairs.

Stay at hotels with fitness centers or swimming pools and use them while on business trips. 

Take along a jump rope in your suitcase when traveling. Jump & do calisthenics in your hotel room. 

Participate in or start a recreation league at your company.

Form a sports team to raise money for charity events.

Join a fitness center or Y near your job. Work out before or after work to avoid rush-hour traffic, or drop by for a noon workout. 

Schedule exercise time on your business calendar and treat it as any other important appointment.

Get off the bus a few blocks early and walk the rest of the way to work or home.

Walk around your building for a break during the work day or during lunch.
