Yesterday I lifted a bunch of heavy shelving (360 lbs total) broken into small loads to my basement garage. I thought it might do my legs some good to put some weight in my arms and walk downhill in steel toed shoes on uneven surfaces in the dirt and hike back up 20 times until it was all done. OUCH .. I was kind of sore.... all over.
I started out slow, but decided to buck up and run the thing a few times. Afterwards it was mostly a social fest. I was trying to learn how to do double three turns (Adult Gold Moves have them) and Twizzles .. they are like spinning, but in a moving straight line. Years ago only ice dancers did them. Now they are a part of freestyle skating.
