You stand strong and you will prevail!
I just started working in a gym as a PT, I am not as big or as strong as you guys, but I still get hate. Though I bench more than the trainers I work with can deadlift, and most guys here at MAB warm up with my max.
Our deepest fear is not that we are inadequate. Our deepest fear is that we are powerful beyond measure.
"When in doubt, just get really, really strong. It tends to cure most problems in training – and life." - Wendler
