Iron body

One of the classic tricks of the strongman, I call this one the ‘iron body’. The effect is quite striking, eventhough it involves very little else than simple physical and mechanical principles.
Lie in between two chairs, and get an assistant to climb on top of you and stay there… Think you couldn’t do it? Think again..Setting it up…
Position 2 chairs, facing each other, about 15 inches less than your own height apart.
Place a third chair in between, facing at 90 degrees to the other two.
Sit on the middle chair, then lie between the two side chairs.
get an assistant, or a member of your audience to remove the middle chair (or even, do it yourself, though this will prevent you from getting it well out of the way).

You should be able to hold this position quite comfortably.

Climbing on…
When your helper is about to climb on (s/he can either use the spare chair for this, or you can simply offer them a hand), make sure s/he does not place his/her weight directly over the centre of your body. If s/he does, you will double up like a jack-knife.

Weight distribution is the key to this trick: place one of their feet on the centre of your chest, and the other one just above your knees.
You should be able to comfortably withstand the weight of a full grown adult doing this.
