Hi

I am 72 years old and first started Guitar in June this year

I am in good shape and know how to handle my back when in bothers me

I feel that I am straining to get my arm so that is hinges free on top of the Guitar body and this seems to pull my shoulder up

Thank you all for the advice

I went to a guitar shop tried a couple and found a 7/8 guitar that seems more comfortable to play (An Ortega R121 Guitar) unfortunately it is rather expensive. (I live in Israel)
