Exactly how much should i exercise throughout the week?

Depends!: Depends on many variables. If your job is very physically active, you'll need less formal exercise. If like me, you exercise in snip-its throughout the week, you'll need less. General recommendations are 5 days x 30m of moderate exercise or 3 days x 45 minutes of vigorous activity! get as much as you can without obsessing! spent 3 hours dancing last saturday at my daughter's graduation-exercise!
