I was at the gym squatting when a guy I had never seen before deemed that I needed help. I didn’t. He came mid-set to ‘spot’ me, literally hugging me from behind as I was lowering down. After that rep I stopped, pretended I was done, and left the gym. This was 5 years ago. What bothers me to this day is not slapping that MF instead of cutting my workout short and leaving.
