I can feel that. I go to a Retro to train. One power rack, one Hammer Leg Press, one Smith Machine. Thankfully the senior citizens pretty much ignore this equipment. Just the other day I'm doing heavy cable rows, I'm getting ready to do my next set, I'm sweating, breathing heavy getting my straps set and 2 old ladies ( I'm sure they are nice people) decide to stand behind me and have a chat. It took everything I had not to say GET THE FUCK OUTTA MY WAY !!!! Drove me nuts.
