I moved 9 windows lifting them up into the building opening (don't have the porch attached yet) about 4 feet and 90 2x4's today as well as lifted 4 sheets of 5/16 inch ply wood up about 6ft and held it in place till it was nailed securly... my butt muscles hurt, my back hurts, my arms hurt, my shoulder hurt....Does this count as a work out? I hope I lose below my 147...been there multiple times for the past 2 years... does that count as losing hmmmm 50 pounds :D....
