This is gym-related, but not really weight-loss-based:
Holy CRAP on a shingle! I just had an AMAZING day at the gym. Almost every move in the gym (all but one) I upped the number of reps per set by at least 2 (making 10 total), to as high as 15 on a few sets. I could tell something was off when my first real set of the day, after warm-up, was assisted pull-ups at 50lbs, and instead of my usual 8, with the last crappy two not quite making chin-height, I instead managed 14 reps, with the same last crappy two, before I stopped. My next sets were 12/10/10, so not exactly a fluke.
Later on, on the one-handed isolateral low row, I maxed out the machine (putting 5 45lb plates on each lifting arm) and managed to pull 10/12/15!/15!
I dunno what changed! I finally got some new supplements in, but this is hardly major stuff, just a multivitamin pack and my usual pre-workout...
Wait.. Huh! I tried a new pre-workout mix alongside the regular one, a grape (eww) powder drink I downed in the car on the way in to the gym.. One dose out of a trial pack shouldn't be having this much effect, but if it IS that, then.. Maybe I need to get this stuff. Those kind of results.. Might be worth it.
Y'know, now that I think of it, the one move that didn't advance was most of the way through the night. I counted it as a fluke due to being distracted/rushed when I realized the gym would be closing before I could fit everything in, (which I did, one non-associated move I'll put in tomorrow..) but maybe that was it.
