She is truly amazing, no doubt. She actually was using more than 600 pounds because we have to add on the weight of the machine which was probably another 45 pounds.Speaking of women who don't look as strong as they are, back in, I think, 1984 Leslie Deniz walked into the gym where I worked out in Tempe, Arizona. I did not know Leslie at the time, and she looked just like a big, overweight young woman who looked very out of place at that particular "hard core" gym.To make a long story very short, Leslie started doing her bench pressing. She worked up to three reps of 330# by her sixth set. Two or three weeks later, the gym held a bench press contest. There was no contest in the women's division. Leslie benched 375#. I also saw her squat over 500#. Looks can definitely be deceiving.
