Went for usual run at 0530 with the dogs, then to weights and did 3 sets of 10 and 1 set of 15 skwaats with my own bodyweight on my shoulders, followed by Bulgarian split squats with half my bodyweight, etc etc.
felt pretty solid.
Got to work. Discovered all of the properties I have to look at today are on the top floors of high rise blocks, with no lifts.
I am not sure if anyone has ever actually died of quad pain.
