The lovely Barbara is:
Five rounds, each for time of:
20 Pull-ups
30 Push-ups
40 Sit-ups
50 Squats
3 minute break between rounds.
I did not feel up for squats with my gibbled knee, so I eliminated them. The full leg brace added a couple pounds for my pulls ups for sure, and turned my pushups into one-leg push ups. My situps were also with one knee bent, the other straight, which added a new dimension. Pullups were deadhang on the woodgrips. Overall I was happy with my time of:
43:00 minutes.
