200 Situps App

Ok, so I've been liking the C25K app so much that I decided to download the 0 to 200 Situps app as well.  This program is similar to C25K because it's 3 days a week, for 8 weeks.  Although both apps are created by the same company, there are several differences.  First off, C25K is free, 0 to 200 Situps is $0.99 at the Apple app store.  Is it worth $0.99?  We shall see at the end of 8 weeks.  But really I feel the C25K is way more fancy.  0 to 200 Situps does not allow you to change skins or listen to music like C25K.  Just like C2K you start each workout with a 5 minute warm-up.  But it doesn't say what to do during this "warm-up" period.  Stretching? Running? Idk.  I guessed and did jumping jacks.  I also feel that it might be too easy for some people.
Here is day 1 workout:

I was like 18 sit-ups? That's all?  I can't wait for it to get a little bit more challenging.  I just figured this would be a great workout to do on the days in between C25K.
Here's my workout schedule:    

• Monday: C25K
• Tuesday: 0 to 200 Situps Challenge
• Wednesday: C25K
• Thursday:  0 to 200 Situps Challenge
• Friday: C25K
• Saturday: 0 to 200 Situps Challenge
• Sunday: Rest 

Too bad I didn't start these to programs at the same time.  Then I would finish the 8 weeks at the same time.
