oooh...

climbing.

it was brought to my attention that tightening your core muscles will prevent you from swinging uncontrollably in a lot of situations. it is probably an instinctive thing to do in some circumstances, but now that it is on my conscious mind, i hope to use it more. i also saw this one really good climber use a neat move where his right hand and right foot were directly in vertical line with each other. he flagged his left leg to the right, in front of his body, to bring his left hip closer to the wall so he could reach something to his left. he was doing a bunch of these in succession and it looked like he was flipping back and forth. good oblique workout. i wonder if it wastes too much energy. it's a lot of movement...
