My grandpa told me this joke when I was young, so it’s probably quite old. However, I haven’t seen it here, so I thought I would share.

A man wanted to increase his arm strength, so he decided to start a daily lifting routine.

He started by holding a potato sack in each hand, lifting his arms from his sides and holding them up for 5 minutes.

He repeated this simple exercise daily for a week.

Feeling like he wasn’t making much progress, at the start of the second week, he instead lifted two potato sacks in each hand.

Each week he would add another potato sack, so that just over a month in, he was holding five sacks in each hand.

Finally, at the start of the sixth week, disappointed by the lack of results, he decided to make a drastic change to his routine.

He went back down to one sack in each hand, but this time, he put a potato in each sack.
