back and biceps

I think I worked the hardest on this workout out of many of the others. I tried much harder to work on my form. I went back to the pull up bar and did 7 pull ups close grip underhand. That is not that many but I went all the way down to elbow lock and then pulled myself back up. That is much harder then going down say only 3/4 of the way. I was able to do 2.5 wide overhand pull ups. Those are super hard for me. I worked a lot with the bands, really just witht the green ones. It confuses me a little because the guys that are using the bands are all using the green bands for the pull ups and those are the easiest of the three that I have. I sometimes am using the black bands which are the hardest. The confusing part is the guys using the green bands are so much more ripped and leaner and stronger then me but I am using the black bands. There is no way I am as strong or stronger then some of these guys. I must have bad form. I spent more time working on my form and incorporating an Isometric hold on some of the pull ups to get more of a pump.

As much as I say I hate the ab workout I think I continue to get much better at it. I am not as spent from doing one of the moves or I can make it through the whole move without a break. What upsets me is that I am not losing the flab on my stomach or tighting it up or at least it does not seem that way. The bad part about that is my 33 jeans are getting tighter not looser but not because I am getting fatter but because my abs are becoming stronger and larger and therefore adding onto the thickness of my midsection.
