Man, it is RIDICULOUS how much stronger I feel when I lift at home (in Austin) versus my long trips to DC. When in DC, I'm cold, I don't have access to cheap BBQ every week, and I'm mostly sitting around all day (and thus, am stiffer). In Austin, the weather is great, I eat everything I need to, and even though I work in the office, I move upstairs and down for meetings.
When in DC, just about all of my lifts suffered. I didn't hit my needed bench or squat reps for the 5's and 3's weeks, and BARELY got 285x1 on bench.
Now, I'm back in Austin. Yesterday, on squat, I had a solid 425x1 (new PR). On my 3's week, I barely eeked out 400x1 (didn't get the next two reps).
Hopefully once DC warms up a bit, I won't have so much trouble. Even with longer warmups, I always feel "off" there. Doesn't help that they have shitty equipment at the gym there: one power rack and two squat stands (without safety bars, of course).
Compare that with my Austin gym, where we have 5 power racks and 6 stands. Also, almost every "hardcore" DC gym is also a Crossfit gym, but of course, to use the Crossfit equipment, you have to pay the Crossfit fee, which blows. They still allow you to do Crossfit-style stuff in the regular gym, which is frankly a little terrifying. There is no regard for safety--you have people squatting, deadlifting, snatching, and cleaning all within a 20'x20' area (also, there is a concrete pillar right in the middle). Luckily, no one is snatching or cleaning too heavy an amount of weight, so they rarely have to bail, but if they did, someone is getting smashed. I guess as long as you sign the waiver, they don't give a fuck.
