This looks like BIG fun!!
When the kids where little tykes, Linda used to use them as baby-barbells. She would do overhead presses, sit ups, bicep curls, and squats with using little Tierney or Taylor as weights. It was a great bonding experience for all of them. Well, someone stole her idea and is making big bucks from it. A gym in London, recently introduced "human barbells". They hired five men of various sizes (including two dwarfs and one 340 pound man) that exercisers can use for weights instead of boring barbells. For no extra charge, the men will yell things at you while you are lifting them.
