I did the math. If I work out one hour a day I am devoting only 4% of my day to exercise. 4% what is that? It is so tiny compared to the 33% I devote to sleep and the 16% I spend watching tv. This is my health and my life I can give up 4% of my day to keep myself healthy.
So think of that next time you want to cut your workout short or not do it at all. Is your health worth 4% of your day?
