I went from doing barely 1 set of 8 reps lifting 15 lbs dumbells to doing 2-3 sets of 10-15 reps. I just recently bought some 25 lb dumbells and I'm looking forward to using them.
I went from 2 pull ups to 13 pull ups (any type, really; wide is definitely my favorite, though). I would like to hit 20.
I went from barely being able to do 15 Mason Kayaks to doing 80 in a row. 100 is my goal.
I think the first time I did Plyometrics, I made it through about 5 minutes before I almost collapsed. The last time I did it, I didn't stop and went full force the entire time.
The most improved, though, has to be stretching and stamina. Sounds weird, but I'm basically back to where I was when I was 16 and in martial arts (being able to do the splits, etc). I feel really flexible and (this might be TMI) I have a lot more energy in the bedroom. Yes, this is a HUGE benefit of working out.
My focus when I restart is to get a little more bulk going. Weight wise, I'm pretty much where I need to be. If I can lose the last little bit of belly fat, then I'll be golden. I would like my arms to be a little bit bigger and my abs to be a little more defined and then I'll probably just maintain and adjust as I age. I'm really glad I did this program. I kept telling myself I would start sometime early last year, but I never bothered to do it. I was just a lazy blob. Then in December, I finally said fuck it, downloaded the iPhone app and started going. Best decision I've ever made. Around the same time, I also told myself that I would make a bunch of sweeping changes: dress completely differently, carry myself differently, stop being a shut in, face all of my fears. It pretty much worked like dominos... working out gave me energy and confidence, which transferred into how I walk, which made all of my new clothes look better on my frame, which meant people (especially women) actually started approaching ME. I still have days where I feel like a fatso (like this weekend after I went to the club with a bunch of chicks, drank too much, then had IHOP with them... felt FAT and was wearing a fitted black v neck too ... ugh) but overall I feel good about the way I look. And if I miss a workout, I feel terrible. It's one of my favorite parts of my day!
That's pretty much it. I'll get P90X2 in a couple months when I can afford it and I'll keep checking in here on everyone's progress because this thread is fun and I'm still learning a lot of things from people.
