Question: So I have six eight years of trial-and-error evidence to show that I am incapable of building strength to any measurable degree from any form of exercise. I do not show results and I have become tired of working out for no reason. I have put it all to an end and I am seeking alternative ways to build strength. One person told me he can genetically-alter my muscle cells and fibers to enable more strength without exercise - is this possible?

Another method I heard is heavily taking anabolic steroids, which supposedly can build strength even without exercise. At this point I am considering steroid-abuse if it means possible results I can appreciate.

I have never appreciated or have been satisfied with results from any workout program or routine over any period of time, and do not progress no matter what. I do not even wish to seek an expert as alternative approaches is what I am looking for.

Please let me know on any other possible ways that strength can be increased without exercise, since exercise does not work for me -- I have tried everything you can think of and after 8 years I am still where I started at 14.

A 22 year old man who is out lifted by small teenagers who barely workout ... I am a shame of a man and person overall.

Answer: 
If exercise really would not work then your muscles should have wasted away by now and you would not be able to get out of bed. Astronauts who stay on board the ISS for more than a few weeks have to work very hard to compensate for not having to carry their body weights all day long.

So, your muscles are able to repair themselves and maintain the strength needed to do your daily tasks. But it would be an enormous coincidence if this would be precisely the limit of your maximum muscle strength. Given your age (you are not 90 years old), that would be extremely unlikely anyway. So, you will get stronger if you do some exercise.
I have had a problem with the confidence and energy(visible as enthusiasm) which allow me to exercise and feel good until recently and I believe it was diet and sleep related. Because it sounds as though confidence and enthusiasm are likely a large part of your problem, I suggest getting at least 30 grams of protein (even better, the US government's recommended 50 grams per day) and try to sleep eight hours.

Separately, it sounds like you might have a shame issue with working out so that you don't exhaust your muscles fully(to failure) in public. Perhaps you are embarrassed to be seen struggling with what you consider light weight? To remedy this issue, you can do exercises that no one can see you do.

Examples include pushups, tricep extensions, curls, and shrugs. Try these with 20lbs. or less and marvel at how your arms shape up. This can be a ten minute super-set every day before you shower in the privacy of your home. If you've tried for eight years, what's the harm in another month with a new tactic?

PS: A super set is one which alternates muscle-groups between sets, thereby letting lactic acid flush from one muscle group while working other muscle groups.
