Burn Calories While Racking Up Karma Points
Calories burned: A whopping 1,720 for a full day of carpentry, installing rain gutters or building fences. 1,432 for a day of painting and weather-stripping.
Muscles worked: Shoulders (be sure to switch arms while painting); back and quads (carrying bags, bricks and wooden beams); heart (walking around the site). Make sure you can squat easily, lift a brick in both hands and carry them for two laps around your house.
Karmic bonus: A shelter becomes a home.
