Since you mentioned both 3 days and 5 days per week, I split the difference and set your goal based on 4 days per week. So a total of 720 minutes. Let me know if you'd like that changed to something else.
Sorry I didn't post sooner, but I was having log in problems for a couple of days. Please put me down for 2000 minutes. It's about time I really got my butt back into gear.
