I actually thought I was relatively strong for a tennis player but after this thread feel pretty weak.
My max was 295 quite a few years ago when I weighed 190 pounds. I rarely had spotting though so I believe I could have done more as I got 2 sets with this and only tried it one time. My goal was 315 but never got there. After many years I am coming back and after quite a bit of work am comfortably doing sets of 8 with 205.
I am also in the process of attempting to lose weight, and starting to think this is completely counter-productive for tennis as I am adding bulk that is not needed, and strength is really not that important for tennis.
