- Tip #1: Give machines a rest
The average treadmill produces about 2 pounds of CO2 over the course of a 30-minute workout. Shrink your fitness footprint by adding an outdoor run, walk, or bike ride to your routine. In urban areas, choose side streets to decrease your exposure to car exhaust. Still snowbound? Burn those calories by snowshoeing, skiing, or shoveling the driveway.
- Tip # 2: Use machines that give back
Ed Begley Jr. isn't the only environmentalist with a stationary bike that powers his toaster. Members of Portland's Green Microgym also generate electricity during workouts. The Pedal-a-Watt device turns a road bike into a stationary that can generate 150 to 200 watts.
- Tip #3: Try a low carbon diet
Athletes know that a healthy diet improves performance. Green your menu by choosing local and organic foods. Opt for fresh veggies, since frozen foods require more energy for storage. Cut back on over-processed, over-packaged energy bars, which sap resources during manufacturing and transportation. Consider carbon emissions when choosing your source of protein. And track your progress using a food-footprint carbon calculator.
- Tip # 4: Give old shoes a new life
Perhaps your intensifying workout program calls for shoes with more support, better fit, or smarter design. Your old kicks needn't end up in a landfill. Organizations like Shoe4Africa and One World Running donate used sneakers to overseas athletes. Nike will transform worn-out shoes (of any brand) into Nike Grind, which is used as a surface material for basketball courts and running tracks.
