Obama's Super-Strength

Like Robert Farley I'm not sure whether to believe these tales of super-strength from the German press:

He goes and picks up a pair of 16 kilo weights and starts curling them with his left and right arms, 30 repetitions on each side. Then, amazingly, he picks up the 32 kilo weights! Very slowly he lifts them, first 10 curls with his right, then 10 with his left.

32 kilos is about 70 pounds.
