11.Exercise for a Good Cause
Need motivation? Sign up for a charity run or walk that draws attention to an earth-friendly cause. Or volunteer to clean a park or beach, plant trees, or tend to a community garden. National parks offer great active volunteer opportunities such as leading hikes; serving on bike, horseback, or ski patrols; and building or maintaining hiking, walking, or biking trails.
12.Soothe Sore Muscles
Treat yourself to a massage: It relaxes muscles, helps your body release natural painkillers, and may boost your immune system. Other natural remedies include heat, stretching, and rest.
