A healthy adult should really be able to carry eight litres (yep, that's the measurement) for half an hour, shouldn't they?
I have a horrible feeling I might have to do some exercise at some point in my life

8 litres of kitty litter probably has a similar density to sand, which is roughly 1.6 kg x 8 = 12.8kgs or 28lbs or two stone. That is a pretty damn heavy thing to be carrying for half an hour.
Grr, you strong!
