Just did 12 chinups off a balcony. Whew. Abs cramping. Got to rest. That was dumb.

Once when I was getting to 30 and climbing a lot I decided to focus on pullups. Got so I could do somewhere near 30 nice and slow. And the new bulk and strength led to some bad pains in my shoulders and back and core. My muscles could do more but it was making me nauseous so I stopped.

Never understood it but the pain was like a crimped posture. Maybe I needed yoga or more supermans or something.

Not that chinups would have made me a good climber, the good climbers live in another dimension and see things I just don't.

Edit: Oh! another stupidity. I was at a fancy gym when I was 20 and they had this air assisted chin up platform. I did as many as I could at 100%, then told it 95% of my weight. Did like 4 more. 90%, 85%, 80%... kept going until I wasn't able to do a pushup at 10% of my weight. Then I realized that I couldn't pull downward with 20# of force. Couldn't turn the car's steering wheel to get out of the parking lot. Did a lot of stretching but was still toasted for more than a week. Don't do that!
