Another critical factor to be aware of, is the efficient use of time.  If a routine is performed in approximately one hour, the muscle gains will be much less than if the exact same routine was performed in half and hour. This aspect is a  “secret” to most.  Time is one of the most effective ways to increase intensity of effort.

When performing a  workout, your breathing should be more rapid than normal.  This should start to happen within the first minute of your workout.  Ideally, your breathing should not return to a normal pace until at least ten minutes after you finish your workout.  If your breathing pace has not increased, then you are not training rapidly enough.  This will seriously reduce your rate of muscle gains.

I have rarely seen guys at the gym willing to train at the required pace.  An unwillingness to work hard is thenumber one reason for lack of huge muscle gains.  To inspire maximum results from training, you must train hard.  Your breathing and heart rate must be elevated.  But you know  what. Such a pace only needs to be sustained for fifteen to twenty minutes.  Any additional length will prove a waste of your time and effort.

When I first learned this secret, I focused on this one factor almost entirely.  Doing this had a direct impact on all of the other factors involved.  Training the largest muscle groups of the body at an elevated pace, until momentary exhaustion, literally forces you to workout briefly.  Fifteen to twenty minutes maximum.

By forcing a time constraint on your workouts, you immediately raise your level of intensity. Simultaneously, you will have managed to reduce the amount of time spent training.  The  absolute opposite of this method is working out six times a week,  in a vain attempt to build muscle fast. This is simply not an option.  If that was what natural bodybuilding really required, I’d consider it to be a bad use of my time.
