Yeah I got to train at a powerlifting gym over the summer when I was staying with my dad. It was a great atmosphere and I learned a lot there. Haven't been able to find much in terms of a more serious gym around here, at least nothing within reasonable driving distance. After I graduate I'll have to try to find something wherever I end up.
One thing I'm pretty happy about is that as my bodyweight has gone up my strength/weight ratios have actually gotten higher. I think this may be due to better leverages - I remember someone (I think Jim Wendler) saying that a lifter should take their height in inches, multiply by 3, and weigh that much in pounds to maximize their leverages. So according to this I should weigh at least 213 lbs at my height. I'm around 210 now, and I have some fat to lose.
I've actually been thinking about weight classes and everything and I'm a little confused as to if I should even be thinking about that yet. It seems there are 2 schools of thought here - either maintain your weight carefully to stay within a certain class, or just get really ****ing strong and then cut fat to end up wherever you should be. Over the summer I noticed the guys in the 198 class seemed to be an inch or two shorter than me, and the guys in the 242 class were an inch or two taller, so I'm thinking maybe I need to be in the 220 class at my height. Not really sure if there's a rule of thumb here or what, just going by what I noticed at that gym. These guys also didn't have an ounce of fat on them.
