now, to attempt to answer your statements so i can then watch you disagree with facts.
you have imbalances due to you using a crappy program that you designed yourself. the eastern bloc countries have shown for decades they are superior in designing strength programs. a key point they focus on is very few movements and they always get strong and they hardly ever have weak links or imbalances. they design well balanced programs. many great proven programs that are recommended today are based upon eastern bloc ideals. in others words they work, they are far better than anything you could design as they were designed by research scientists and proven on thousands of athletes over a span of decades. you would have to live thousands of years and work out that entire time to try and prove that amount of evidence wrong.
many great coaches dont do any prehab work as they dont need it. they only use when it is needed which is when recovering from an injury. are you injured? are your imbalances diagnosed from a professional or just visual imbalances that you think you have?
also, when you come onto an open forum and ask for advice and you are given what you need, listen and learn. if you dont get what you want, it may be what you need, so listen and learn. when you get what you want, it may not be what you need. i gave you what you needed and only want to hear what you want. they are not the same.
as for why people look for faster ways, why not. what does that idea prove. that we are lazy americans that dont want to work for what only hard work will give us. all the great will say common things like, work hard and work consistently and that is the reason why they are great. liek ronnie colean once said, everybody wants to be be big but no one wants to move big weights. well there is a reason he is a great, he worked hard and worked consistently. and it also took him what, 10, 15, 20 years of hard work to get there. most will never get them over a lifetime of working as they want shortcuts and are not willing to work.
now, you dont have to listen to anything i have said as i have a feeling you wont anyways. you can continue on with half ass results with your half ass plans and your half ass effort and get no where. so i write this more for the benefit of others. so that they may learn how to get better results and not make the mistakes you want to make every day.
