Failure defined today was doing elevated tricep dips, reaching failure and getting stuck on the two chairs, unable to move up or down, left or right, and absolutely no way of getting off the chairs. Only possible ways of getting out of this situation = falling off the chair or digging very deep and finding a muscle somewhere that was working to get me off the chairs. Found a muscle. A very small one. Was a particularly funny moment when I thought "that's it, I am stuck here" and no one else in the house was up yet. Silly woman.
Despite getting stuck on the chairs, all exercises done and dusted early. I had to do yesterday's exercises today as I didn't get home until too late and had left them for the afternoon. Serves me right.
