Alternative to Walking
What if you are tired of walking as a form of aerobic exercise? It is very likely that we are going to get tired of what we are doing repeatedly. So in those cases it is time to make sensible changes to our aerobic routine.
We can include other aerobic exercises like jogging, running, swimming, etc. We could even consider joining a class, working on a stationary bike or just biking around the neighborhood.
There are other things like the elliptical machine and some light weight lifting tools that can be easily done indoors as alternative to our daily exercise routine.
