My physical grace simply amazes me

Last weekend The Wife and I cleaned the hot tub which involves draining it, hosing it out, etc and then refilling it. Once it is being refilled we have to add various products because we have such hard water (helps to keep the minerals from depositing on the hot tub and in the pipes). To facilitate this process we had removed the cover, folded it in half, and placed it on the lawn about a foot away from the concrete slab upon which the hot tub rests. I was walking around the tub pouring in the first bottle when I suddenly found myself on my back staring up at the beautiful blue sky. Apparently I caught the edge of the slab, slammed down on my right knee (giving myself road rash right through my pants without tearing my pants...), and then proceeded to roll across the cover. Of course, no one was filming this because it was totally an America's Funniest Home Videos money shot. I managed to not spill the bottle of hot tub additive and found it happily bobbing, open end up even, in the partially filled tub. At the time, I was focused mainly on my knee because that was what hurt but it was very apparent on Monday morning that I had pulled/strained muscles all along my right side. My trainer was very understanding on Monday night (and quite concerned - asked if I had hit my head etc) and helped me stretch things out. We even had to make adjustments for my shoulder on Thursday night. For those of you who know me IRL, you know that I am prone to this sort of amazing display of physical grace. This one was simply better than most of my displays... I am such a tool.
