Try indoor bouldering.

“I started with bouldering because I didn't have a climbing partner and the idea of depending on someone else for my safety felt like a lot of pressure for a first visit. After about 15 minutes of climbing, my forearms felt like they were filled with concrete. Not sore - literally unable to grip anything. I couldn't open my water bottle.”

“I went to the bouldering gym alone for the first time and I have to admit that I liked it! I was very nervous at the beginning (thank you everyone for your support!), because I was so paranoid about what others would think if they saw me struggling (I'm still a beginner); also, I went to a gym that I didn't know and I was afraid of not knowing where to go or what to do.”

“Yesterday I went bouldering. It was at an indoor gym for beginners, so I didn’t go too high (I’m also scared of Heights). I know I didn’t go super high, but I’m proud of the bit I did and I’m super sore the day after.at the same time, the instructor and my family kept telling me to go higher or to hang off of a ledge, both things I’m not comfortable doing, which made the bit I did seem kinda like a failure :/”
