Just wanted to thank everyone for the various advice thus far in this thread. I've been taking the gym seriously for about 3 months, but about 3 weeks ago switched to the beginner routine from the OP and have already been seeing greater results. The suggestions about pull-ups were spot on: got a pullup bar and have it on the closet door on the way out of my room and try to do at least a few various gripped pullups as I pass by it throughout the days, and already I can do 5 pullups, 7 chinups, and have seen my other lifts like bench press go up quite a bit in the process. Fantastic advice, and anyone having trouble should definitely heed that advice 100%.
If only it were as simply to improve myself with dips, but I've already achieved my first major goals at the gym (doing a pullup, benching my body weight, squatting over 200) and a lot of that is thanks to you guys. This is an amazing thread filled with awesome people who give out info that trainers charge a boatload just to give 10% of, and you guys are really awesome for doing so. Thank you.
*edit*
Scratch that, hadn't tried in awhile and decided to try and do some dips today, and was able to do 3 sets of 5, 5 and 6 reps. I couldn't be more excited right now.
