How many programs can I join?

I will keep joining until something works!  I just bought "Walk for Weight Loss" from the itunes store on my iphone.  If anyone else is on it, let me know so we can "friend".  I am hoping that by adding more speed intervals that it will up my progress.  According to the program, if you are a beginner (which I am saying I am) I need to walk 7 days a week.  You get to drop to 5 days a week when you actually need a rest.  This is 15-60 minutes/day. Let's go!

Any other programs I can add? :)
