Thanks again KTG, onwards to level 4!
D1L4: 25 rounds, with 7kg backpack.
With backpack weight is not really a good idea. Backpack zipper open up involuntarily halfway thru the workout. Had about 1min break to fix back everything.
Breathless after completing the 20min rounds. Tried sitting down to rest, but head starts to spin, quickly get up a start pacing around. For a while everything is fine.
