<human>: Summarize the given text in a few sentences.

So this afternoon I went to the gym feeling pretty energetic and inspired, I'm pretty unfit and have been going to the gym for a few months because I just got sick of it. Anyways, today I did one of my hardest sessions to date, running, cycling, pullups, push ups, consistently for about an hour and a bit. Needless to say, I was fucking tired by the end, decided to have an [Up and Go] to finish. I finish chugging it down and am just walking out when I see the rowing machine. 

This machine and I have been having quite a feud over the past few months, I always do a 2km row to finish off my workout, I decided today would not be an exception. I jump on the machine and expend the shards of energy I have left to get a time of 9:30 (this is impressive for me). Afterwards I'm feeling accomplished but albeit very tired. I kind of stumble around the change rooms for a while and realise I'm not feeling too good. I put it down to the sweat and decide to have a cold shower. 

While I'm in the shower, I feel my stomach rumbling, I burped and then, out of fucking nowhere, comes a barrage of watermelon and protein drink straight from the bottom of my stomach. Shit. Luckily I managed to bend over so it mainly splashes along my ankles and feet but I'm now on my knees desperately trying to guide my pink and white puke into the drain without taking a bath in it. Luckily, I think there was no one else in the changerooms to see the liquid seeping out from the shower stall, but it smelled like shit in there so I just quickly got changed and left.
<bot>: Gymmed hard, drank a protein drink before finishing so it sloshed around in my stomach violently for ten minutes straight. Had a shower, shit got messy
