Weird Guy at The Pulse on Jan 6th

UPDATE: I didn't expect this post (?) thread (?) to receive the amount of attention it did, for everyone curious, yes, I got in touch with employees and managers at The Pulse, yes, the special constable has been notified (they are very kind!) and yes, he has been warned of his behaviours at The Pulse and is not allowed to approach me anymore. For those who private messaged/ direct messaged me: Thank you for your kind words, I'm so sorry if something similar happened to you-- it is sad world we live in. Please stay safe on and off campus!! Do not hesitate to reach out to the staff here! To everyone who helped me and validated my feelings online or met me in person, THANK YOU!!!

I was working out at 6:30pm-8pm yesterday night alone and when I was doing leg presses, a guy asked me how many reps I have left-- which is a normal question to ask. Later on, he approached me on the second floor and said he was new to the gym and asked if I could help him on a few machines, mind you, I'm pretty passive, so I agreed and he asked me to help him with the leg curl machine. It was normal at first, I asked him what year he was in, and turns out, he was a Grad Student in engineering. (I'm a FIRST YEAR STUDENT who turned 18 TWO MONTHS AGO). Knowing my age, he proceeded to ask me how to use the hip abductor machine (where you basically start with your legs spread open or closed and try to open or close it), I didn't feel comfortable doing it, so I told him I didn't know how to. He then proceeded to ask me how to use the side leg raise machine-- which I also didn't know how to do and didn't feel comfortable demonstrating. He said it was fine and perhaps I could teach him some stretches. In my head, stretches seemed the most appropriate and normal but when we went up to the third floor where the dance studios were, he saw that there were around 7-8 people and said nevermind even though it clearly had space to fit us. We went back down afterwards and he decided to "check the studios upstairs" one more time and brought me into the same dance studio that had people inside and brought me to the equipment area that was behind a wall inside the studio and said we could stretch there... mind you, the equipment area is not that wide. I got red flags all over and ran to a group of people right as I declined "stretching" with him in the equipment area. The group of people hung out with me for around an hour ( we did a yoga class together during that time) and when it was done, he came into the room, I wasn't sure if he was waiting for me or what not... but he talked to the lady instructor who lead the yoga class instead. the group of people snuck me out right after. He wore a green quarter-zip cardigan with cuffed sweats! If anyone also got approached by him please stay safe!
