Consistency is key. I am in the same boat as you. I am so busy with work and college that doing a consistent PE schedule is hard, so I do what I can when I can. I have been doing it for about 2 1/2 years, on and off, and I have seen incredible gains, but I never deviated from the newbie routine. That routine is the core of everything one needs to create a better penis. But like all workouts, it can be modified to fit your lifestyle, especially after nearly a year of doing it. My advice, which may be told otherwise, would be to keep the newbie routine as your foundation but perhaps add something to it (extra time jelqing, ADS, longer stretches, etc.), whatever makes you feel like your workout was worth something at the end. I actually had to skip yesterdays workout for a day full of final exams and work, so today (when I have time) I’m gonna devote a fair amount of time to PE.
One thing to remember to is that this stuff takes time. Many men come here thinking this is the magic cure and that after a few workouts they are porno ready. That type of mindset is false and discouraging. Be patient and keep updating here at Thunders, because a ton of guys here are more than willing to help and encourage each other. I hope this helps bud.
