It was a tongue in cheek comment.
A few friends of mine were avid climbers and I'd occasionally go with them to a local wall.
At 17 stone, the overhangs were killer for me.
I kept suggesting they tied 5 stone around their wastes and tried it again, but they were too busy practically running up and down the side of the wall.
Their power to weight was on a completely different level to mine... Didn't fancy their chances in the front row though
