Congrats on the 3 days!

How long do your health kicks usually last? Maybe focusing on keeping 3 days for a long period of time will keep you going. If you do 5 days its just a bonus. Research shows (I actually saw this in a text book not heard it from someone that read it in fitness magazine) that people that stick with it for more than 6 months stick with exercise are less likely to drop out.

Sunny - I think your new commitment to exercise 5x/week is terrific. But why not see how uping the ante at 4 days works before you go right to five. Everything requires a gradual progression and it makes for an easier transition and acclimatization. Best of all better chance at success. I'd like to hear back on how your first few weeks go.
