So yeah I was doing standing dumbbell back extensions and happened to see a guy looking at my ass. Standing dumbbell back extensions work the hamstrings and look odd because you have to bend over to get a stretch in your hamstrings and it looks like you are deliberately poking your ass out. He could have been just admiring my form and taking notes so that he could do the exercise himself but his eyes stayed on my ass and my count was completely thrown off. How do you all feel when you know someone is watching you in the gym?
