Hey guys thanks for replying.
As some have pointed out, Strength shouldn't rule over technique, which I am sure everybody already agrees on so no need to get all captain obvious, but I do often find myself trying to finish a choke that for one reason or another just isn't connecting properly.
I might get a really nice deep collar grip but if I'm sparring against a good opponent or just a very strong one, I oftentimes loose some inches of the grip before applying the choke. I'm sure you have been in the same situation many times yourself but rather than letting go of that grip which you have been fighting to get and starting all over again I see no problem in filling in the gap with strength. What ever makes the guy tap!
In addition, if your fighting against a really good opponent, you might not get a second chance to get that grip.
I couldn't agree more on this but it goes beyond the bjj scene I think.
Prior to bjj I had been doing mma, wing tsun and alot of other MA's and I still have a vivid memory of people giving me that "your using to much strength" which I'm sure I was being somewhat big and strong at the time, but it just seemed like it would only come up when they couldn't get whatever they were trying to do to work.
Offcause if you have really poor technique you should be working hard not to use your strength but if your techniques are solid, I see no problem using strength as I said before.
Ultimately I don't think there are many athletes left in the world of combat sports that don't strength train.
I'm having a hard time visualizing the tennis ball pull ups.. How do you hold on to the bar while squeezing the balls?
I don't agree on the whole pensil "if your not shivering, your not working hard enough" test and I really can't see the correlation between shivering and not working hard enough.
