The best abs I've ever had was actually 10 years apart. 1998 and 2008. Let's review both:
1998: College: I was working out in the gym 6x a week, running 6x a week, and doing abs 7 days a week. Let's just say I had a lot of "free time". Diet was whatever my parents made for dinner, and drinking was about 4 days a week. Mostly Old English. For abs I got up to the point where I was doing 1,000 situps a night, every single night. I actually got to the point where I had testicular pain, and I ran to the Doctor thinking I had cancer. My abs were pretty insane that summer.
2008: Working full time: At this point I was doing weights 6x a week, and running 3-4 times a week. I was actually only doing Abs 2-3 a week, and only for a couple of minutes. The big difference between 1998 and 2008 was that the weights were A LOT heavier in the gym, and my diet was SUPER strict. Cardio in 1998 and 2008 was very similar, everything fast and under 3 miles.
2012: I think I might try to do 1,000 sit ups a night again. I just cut down to 163lbs from 173, and I plan on going into the mid 150's. I went all out tonight and I was only able to get around 125 situps after a couple sets, so It might take a while. So this year my workout will be 5x a week of weights, 3-4 days a week of running, and 1,000 situps a night.
This is today's picture,I only have 3 1/2 abs but I am starting to get the top side pockets. Power Out
