I have tennis elbow on both elbows. I shoot 65 lbs. and it doesn't bother them at all. Once at the NFFA nationals I was have some problem because I was using a long liquid fill stabilizer. A friend came up to me and told me to take it off and my tennis elbow would stop hurting. He was right I stop using it and it stopped hurting. It was keeping all the shock in the riser and hurting my elbow. Don't shoot with your elbow locked and with a little bend in it so your elbow doesn't take all the shock of the shot.
