Another problem is the mentality of always being smart. Being smart almost always mean achieving the same thing with less and less effort. But for some things being smart is being dumb. Why always take the shortest route to minimize walking? Why go over the lawn instead of around when walking is good for you and only <30 seconds will be saved? Is it smart when you'll likely end up overweight, unhappy and with cardiac problems in the next 20 years? And what about your discipline, patience and character in the long run? Doing exercise(lifting in my case) makes you realize your limits and over time you realize that being consistent can really help you change yourself.
