OK, I’ve been able to workout indoors most of the time, plus I do stairs at work. Yesterday I tried a workout in the snow for the first time.
Big difference! Basics were extremely tough, forms were nearly impossible. Couldn’t do anything at full-speed. My feet were either sliding around or getting jammed in packed snow. By the end of the hour I was just putting together line drills and working on balance.
Worst thing was that the leaves are off the trees, so all my neighbors could see me flailing around in the backyard. 
Oh well.
Anyone else working out in this weather?
