> Do 2 months of consistent 3-5 times 1 hour moderate cardio a week. This will prepare your body for the more intense exercise you can start doing after the 2 months are up.

Maybe I wasn't clear about this: I don't know how to maintain a consistent intensity when exercising. I don't have any particular awareness of my heart rate or respiration rate going up unless I stop and literally count. I don't have any sense of how fatigued I am until a good 15-30 minutes after I'm done, and even then it's quite vague.
