Autumn is a beautiful season with the changing of the leaves but it also brings about some hefty yard work in removing them. Raking leaves is actually very hard work and good physical exercise at the same time. Your equipment needs are simple: your body and a rake.  Raking burns about 300 calories an hour while toning your arms and strengthening your back and legs.  Just be sure to stretch first and, to avoid muscle pulls, don’t try to do the whole yard at once.
