I think she knows me and my body well enough that she pushes me right to the edge. Like yesterday's curls into the overhead presses, I had to do 30 reps with 20 pounds plus the EZ curl bar. Twenty reps would have been hard.

My third set, she had to assist with the last seven. I've been working with her for about 4 years, so I'm sure that plays in to it.
