Location: My Apartment BlockSprint - 20 seconds @90% effort - this was outside in the road
Dumbbell Stair Climb - 3 flights, @37.5kg each hand
Sandbag Clean and Press - 10 reps @28kg sandbag
I did this twice.
Total time: 11.5 minutes.
This hurt. I had planned to do 3 sets, but became aware that a third would have taken my legs into the failure zone, which I did not want to visit on this occasion. So I made the second round count by avoiding any rest. The sandbag is relatively light, so the pain came mainly from the combined cardiovascular effort of the successive exercises rather than muscular fatigue.
