I do not know the long term effects of this daily training and I often wonder myself, to what extent can genetics play a part? Are there people out there who can exercise every day of their life or are they going to burn out eventually and have to rest. The only answer I have come up with is that we have to work with the current knowledge we have. What we can do is vary the type of exercise throughout the day or week. If you do a lot of lifting at work, maybe do some yoga or tai chi to bring the muscles back into balance, or if you are on your feet all day sit down on the weight bench or rowing machine. Give your body what it craves.
