    I am a nursing student as well and agree with everything the other student said. What that author said is BS!

    Thanks for the backup!

    There could be a bit of truth to that if you are speaking about steady state endurance exercises... So, if you cycled at the same intensity level for very long periods of time, you probably would have limited gains in cardiovascular fitness. That is why high intensity interval training is so highly recommended.

    If you do nothing but HIIT your levels will plateau as well. If you at the actual data in the Tabata studies, almost all of the CB improvement occurred in the first couple of weeks, then plateauee.
