The recommendation is 30 minutes, 5 days a week. It does not need to be consecutive. So, it's not so much about "lining up" the exercise with the phase, as it is about getting the exercise 5 days of a week. I like to get mine in M-F and take the weekend off!!
There are phase specific recommendations though, as far as the amount of time spent exercising each day:
Phase 1: 5 days, 30 min.
Phase 2: 5 days, 35 min
Phase 3: 5 days, 45 min
Phase 4: 5 days, 60 min
I think the idea here is that as you increase your food intake on the plan, you should be increasing your exercise as well. It is also recommended that you only participate in cardio the first three phases, then add light free weights twice a week in phase 4.
Hope this helps!
