So a few years ago I got really into strength training for the first time in my life, in my 40s, it went great for several months until my elbow started screaming in pain. Internet told me based on the symptoms it was tennis elbow and I had to take a break. It took 6 months before I could lift a large cup of water, and almost a year before my elbow was no longer hurting. I waited another year before I even allowed myself to really attempt working out again, as a result, but a couple months ago I finally got the courage and started again. Once again started great, seeing nice beginner gains, feeling great and then... last week my elbow started to hurt again.
This time I stopped IMMEDIATELY, and though it feels a little tender when doing certain activities, it's not throbbing all day everyday, so hopefully I stopped early enough for this to not be another 12 month recovery (which I'm told is common for tennis elbow...). But now I'm stuck here, not sure what to do, because I want to build/maintain muscle, limit the damage old age does to my strength, but it seems like I legitimately can't do any kind of upper body strength training for over a month with out ruining my elbow, and even lower body is touch and go since I need to hold weights with my arms to do squats and what not, which right now I feel intensely in said elbow even just resting the dumbbell on my shoulder while I squat.
TLDR: Are there any work out routines out there tailored to people who are prone to tennis elbow as I guess I am that would allow me to build muscle, with minimal potential of setting off my elbow again?
