Before I start this off, can I just say I felt like the biggest douche taking this picture? A bit like a silver back gorilla showing off to a potential mate - I am alpha, hear me roar!
Toning and firming up my arms has been one of the main goals during this whole weight loss and fitness overhaul. Even when I was skinny, my arms had always been on the flabby side and it always made me feel pudgy, especially in pictures of the top half of my body. This progress pic is where I'm at right now - I don't have any before pictures but they were fat and flabby and no muscle definition whatsoever. When I flex after a workout now, I can definitely feel muscles, and the flabby part of my arms (especially on the bottom) has definitely diminished a lot. I'm not exactly where I want to be yet, but I'm getting there.
I have to say I am still a major weakling when it comes to push-ups. At least I can do more than when I started (which was about zero) but I just can't get very far down yet. Oh well - I know I'll get there eventually. My goal is to eventually be able to do Plyo push-ups where you leave the ground with the top half of your body between push ups. That will definitely be a while yet though!
My goal has never been to be skinny and weak, my goal is to be fit and strong. I did a lot of weight and resistance training, combined with cardio to get these results so far. Of course you need to watch what you eat if you want to reduce flab and see muscle definition - like they say, a six-pack starts in the kitchen. I use the P90X fitness DVDs for most of my strength work outs.
