Somehow people have turned against building muscle mass and as far as I can remember, there have not been any reputable athletes that have not endorsed lifting weights. Go and pump some iron today. Weight lifting will increase your muscle mass, tone your body and make your clothes feel tighter when you put them on, if you are a true weight lifting machine then you know what I am talking about. Add weight lifting to any cardio routine and it will dramatically increase your overall results from exercising. If you want to look sweet, fell good and be a champ, then you have to mix up your home gym exercise routines and not just walk on the treadmill for a mile or so. That is for wimps and simps!
