How green is your workout?

You recycle, you turn off the lights, you're making conscious decisions every day to reduce your impact on the environment. So why, then, are you still driving your gas guzzler to the gym to walk or run on an electric treadmill?

If you're looking to green your workout, look no farther than 50plus.com and their tips on Earth-conscious workouts. They've got some great advice, including:

• Walk or run in your neighborhood or nearby trails.
• Keep the thermostat down during the winter months, and ward off the chills with calisthenics.
• If you want to stay in, find a used stationary bike, which doesn't use electricity.
• Rehydrate with a reusable water bottle, and ditch the bottled water habit for good.
• Become an eco-runner and clean up the environment while you exercise.

Another great way to keep your physical activity green is to build it into your every day routine. Commute by bike and burn calories while saving on gas and reducing pollution. Do your errands on foot to get in your exercise, and avoid annoying traffic at the same time. Spend time out in your garden growing your own organic veggies and burn fat by hoeing those pesky weeds. Exercise doesn't have to be complicated and it can help you do your part at conserving natural resources at the same time.
