but if and when you get in a,street fight you will only be capable of physical performance at 80% of your potential maximum, you are not going to make any significant improvements in performance coasting through training at 80% effort. That's what i mean about the half hearted Ma attitude to fitnessIf you push to your limit, you may not feel like to do it next day or the day after. It's better to reach just 80% of your limitation. This way, "you still feel like to do more, but you force yourself not too". You will look forward to do it next day.
It's always better to reserve 20% of your energy to handle something unexpected. You may need to get into a street fight the moment that you finished your workout in your gym. It will be bad that you are so exhausted that you can't even defend yourself.
MA is life long training. It's not important how hard that you may push yourself today. It matters whether you will still do this when you are 70 or even 80.
Try to "enjoy your training" is the key.
