how else can you strengthen your squeeze?

[Justin W.]

technique of course is the key in all bjj subs, but if your angle is off just a little that squezze practice will raisae % of a sub!!!

if you're using a technique but the angle is off, perhaps going to a different technique should be the solution instead of forcing it. Squeezing incorrectly can waste a ton of energy but I can see how that would make a difference in a competition if you don't know the solution to the minor angle error, so squeezing harder might be your best bet.
