Looking for motivation

Options
Looking for online friends to help motivate me, share workout ideas, trying to get my old army body back so my wife will love me again lol jk jk she still loves me. I guess my trouble area is cardio, I have a herniated disc in my lower back so any low impact cardio that doesn't require a month per set would be great. I have a lot of good strength training exercises in my brain that I will dig out and share if asked. lets all reach our goals together without going insane in the process!!
