The problem is that they get longer and harder to improve from, I've hit a plateau right now, and I've been unable to get any better for months :/ It's getting to the point that my hands are physically making things harder, I can't do things like long jacks, or jumpjacks well, because to get that speed required, I have to lock my writs and basically vibrate my whole ram :/ Also, my fingers only seem to be able to move so fast, and any faster and it turns into me just hitting them at the same time (kills my left hand when there are left hand drills, since it's quite a bit weaker/slower than my right.) I'll be SO happy if I break this plateau, lol.
