I never did a one arm until a few months ago when one of the pole vault guru's in the state used them religiously. . .
in high school I was taught to block out with my bottom arm, It took me all last year to break that habit doing lots and lots of sand drills. . .
Since this season I have been blocking out again, and after reading this board I wondered if it was because I replaced my sand drills with one arms, my blocking out got so bad I couldn't even do a rock back drill
this week I stopped doing the one arms and started doing everything with both arms and focusing on proper bottom arm technique and I have stopped blocking out again.
I strongly advise against one arms, although I did see a lot of benefit in the drill, I do not think it was worth the loss in bottom arm technique
I'm probably wrong though. . .
I'd have to say that it doesn't sound like the one-arm drills were to blame directly, it was the fact that you replaced a drill you needed with one you didn't.
