I tried my own version of strength aerobics:
1 clean, 1 press, 1 jerk, one squat, one snatch and one pull-up. I did this with 16 kilo (not the pull up).
I then made it harder: 2 clean, 1 press, 1 jerk, one squat, two snatch. One pull up. Ten rounds in ten minutes.
Walk-out: 156 seconds. (combined)
Suitcase walk: day 1 in the first program.
I am quite close to achieving ten minutes non-stop walk-outs. Will test myself anew in one month.
My record with suitcase walk is 1 minute with 44 kilo.
My new wish is to do 1 minute and twenty seconds with 48. (the final goal is three minutes)
