Upper-body training isn't all just for looks. Yes, you probably want a six-pack and you want a sweet biceps peak, or maybe it's just a matter of getting smaller as you get back to fit.
What this program truly does is start building strength. You need to be stronger—everyone does. Daily tasks become easier as you become more adept at lifting weights. In real life, those weights are moving boxes, TV sets, couches, or even friends who need a lift.
Think about that! Every rep, every exercise, every circuit brings you closer to moving things in your life from that file under "I can't" to a file under, "I can." That's powerful stuff. That's real change.
