Just reached one of my fitness goals: 200 consecutive situps Woot!
I used the program on twohundredsituops.com. Very helpful and motivational.
Next goal: 100 consecutive pushups. 😉

Congratulations! Quick question: what workout surface did you use for situps? I tried this program on my hardwood floor and developed an inconvenient raw spot on my tailbone after a week.
Thanks! I do my situps on my weight bench. It’s padded and lets me “lock” my legs behind a couple foam rollers.
Here’s what I use. Nothing fancy, but it works great. http://www.amazon.com/gp/product/B002QJZAE4
