    Also,

    If I can comfortably stay at 90% or more of my heart beat for two minutes or so, should I? Or stick to less time with rest?

    If you are really at 90% of your maximum heart rate, there shouldn't be anything comfortable about it. Even if you are incredibly fit, that's pretty much a full out push and should be very, very hard to do.
