>>76338502 (OP)Iโm fascinated by the concept of climbing. Itโs one of the few forms of resistance training which isnโt lifting, yet you can get decent size gains in your core, back, and forearms without ever lifting a single weight and without it feeling like work, it just feels fun. I canโt think of anything to compare it to in terms of muscle growth aside from lifting itself. Swimming isnโt effective enough, wrestling requires you have other people, boxing is basically just cardio, gymnastics is very physically and mentally fatiguing, ect.
Itโs an avenue for guys that feel like lifting is too tedious, difficult, and boring. Youโre not going to get huge, but itโs literally the best compromise one could make if you still wanted to get some gains without all the effort associated with lifting. Maybe throw in some weighted pull-ups and dips you do at home a couple days a week, and youโre goin to get a decent physique with basically no effort.
