In my case (not op) I don&#x27;t belong to a traditional gym and go rock climbing several times a week. I don&#x27;t really care to go for a run but I love climbing. Also my knees are in bad shape because I am both tall and heavy which means running&#x2F;biking&#x2F;anything where I regularly move my knees hurts. Climbing is nice because most of the time unless I am trying to dyno (jump) to a hold I only use my feet to keep myself against the wall or to statically take my weight while I move my hands.
