10 minutes a day, 3x a week, is the same as the newbie routine, where you perform 3 days on, 1 day off. As you continue with PE, you progressively push yourself from 10 minutes a day to 40 minutes day, sometimes pushing as far as 60 minutes a day on various exercises, limiting yourself to lower intensity to warm up, a short period of high and very high intensities to break down tissues, and switch back down to moderate and lower intensities to keep the tissues stretched for plasticity and remodeling processes. Remember, lower intensity is the same as wrapping with traction around 600g to 1.1kg of loads.
In the beginning, we discovered that only 10 minutes of light, moderate, then 7 minutes of intense exercises caused tissue breakdown. We continued to noticed that gains came from longer period and lower intensity traction loads work much better for rapid gains. But that 10 minutes of high intensity loads remain. Too long of a high intensity load cause the tunica and septum to harden up, speading up the hard plateau where our gains practically stop dead in their tracks. So, learn from our mistakes, and pursue PE smartly, wisely, and safely.
