Gym fat wasting everyone's time So I've been a long time gym goer, but with my school schedule and my kid's activities I've had to give up going right after work and instead use my lunch break every day for my weight lifting sessions.  I've only been going for about 6 weeks but right away I noticed this oddity.  There is this really really large man that seems to come every single day and just completely waste their time.  He doesn't appear to be too terribly old, I'd put him in his 30's and as for weight probably 300, he's pretty tall, so he really doesn't look too round, but he uses a walker for some reason.  I don't know if he has bad knees already or what, but he uses it to come into the gym and he uses it to get from machine to machine.  And that is where my story starts. He shows up at exactly noon every time I see him.  I am there randomly, I shoot for noon, but sometimes it's later, sometimes earlier.  He uses his walker, slowly approaches a machine, and sits down.  He ONLY uses machines, chest press, curl, overhead press, dip, butterfly, etc.  The way he uses these machines is mind boggling.  They are all cable machines so they have a tiny amount of slack and all this fucker does is slam the machine back and forth as fast as possible until the tension hits.  He does 1 set of maybe 10 reps of this fucking hummingbird motion, then he moves onto the next machine.  He does all of the machines that are easy to sit down on, then he leaves.  I swear to god he's in the gym for maybe 4 minutes total. Today I noticed him because a coworker of mine was using the dip machine and this guy walked in and stood there like 3" away from him watching him do dips.  I'm not sure if my coworker stopped early or not, but he left pretty quick and this guy sat down, slammed the arms down 1" as fast as he could for 10 seconds, then he got up and did the same on the chest press. It is literally the biggest waste of time for him to come in and do this every day, I hardly even know what to say about this.
