Every now and then, I can crank out a respectable number of double unders. Usually, this happens when I am rested - a bit of leg or arm fatigue results in quick failure. Today I focused on trying to get DUs throughout a WOD that included burpees and box jumps. As the photo shows, I started off with a good number then struggled. The last round was a bit better as I sorted out relaxing and working at the same time. This is not Earth-shattering progress, but I recognize this as a step forward.
