my name Is Lisa and i live in NJ, now just to let you know i am new in guns and have not gotten my permits yet, did buy my first gun but the reason that i wanted to post to you is because i have arthritis and can help you with the problems with your back as i have been dealing with PT for a very long time for diffrent things and i am working on getting disability as i can't work any more, i always was active with being involved with dogs for over 30 years, well getting to my point and this can go for anybody.
no manner what you do is exercise stretching is every important and you may not know that you do not have a back problem, do you go to a chiropractor???? that is inportant as well as acupunture. that really is not my thing and have done it and it works.
before you go to the range you should do some exercises to stretch out and then you add to that by getting stronger.
try to do some exercises before you do go to the range and see what happens after that.
