Bodybuilding? In all honesty, one day i got off of my daily cardio-based routine (running/elliptical/bike) and picked up some dumbbells. I used to do my strength training with my own body weight, i.e. pushups/situps/pullups/etc... free weights seemed to help.

It helps me deal with the stresses of every day life. In lots of way it helps me stay healthy, both mentally and physically. It's an AMAZING feeling!
