Sit-up/Crunches routine continues every day but Sunday. Sunday is rest day. Pull-Up Routine Monday-Friday. Biking Routine only when I have work/
( If I do indeed get a job I foresee this routine to double or even triple in intensity as I get a gym membership. I'm not going to do any bulking( At least not to a grand extent. Just to fill myself out and get regular ).
Hey pink! First of all, I agree with what most other folks have said, in that you definitely still have some subcutaneous fat, and that working off that fat is the only way to get the best results.
I'm in a similar position, just a bit further along, in that I went from 280 to 170 last year. At first, I definitely had a lot of extra skin around my middle, but as I've gained muscle and time has passed, the skin has definitely tightened, stretch marks and all. I still have a bit over the lower abs that I'm sure is partly fat, partly skin, and that I may never get rid of, but I still look a lot better than I did 6 months ago. I wouldn't be surprised if you see the same results.
Finally, you may be overdoing it with the crunches. 50 is a lot of reps for a single movement, and doing it twice a day, 6 days a week, is probably overload. Work in other ab exercises. Get in the roman chair or on a swiss ball. Try reverse crunches, leg raises, cable twists, bicycles, v sit-ups, russian twists, etc.
Oh, and adding one pull-up every night is unrealistic.

Pull-ups are tough, and not many people can do more than 10-15 nightly.
