Have to agree if the think tank is full you are slower.

Free fight shadow boxing just going nuts getting them out there with no thought, moving and hitting.

(no need for pre thought, you know exactly how to hit already you've done it millions of times already).

Do it without gloves dont grip your fingers stay loose. Warm up all your joints, stretch them lightly,fingers wrists elbows shoulders then totally, shake hands out, shake arms out, get them floppy and free feeling.
Then free flight air punch from a low relaxed guard, with your arms relaxed ,with out thinking anything or analyzing just have total fun for while and make some mistakes. No power just touches.Just jab or do rising straight shots vary when your loose enough between elbow out and elbow down so that you incorperate all muscle structure around your arms. Also if you hold a smile and have fun, your brian will give you more space to work within any given moment.

Then after a few sessions of free flight, not caring and you feel more free and empty; you then start to only think about getting your hands back; very fast, as fast as you can ; that way you go past the pre thought of moving them outwards. If the thought isnt there at all ,how can they read it on you?

The try hitting someone but your whole intent is getting your arm down onto their lead arm as fast you can after the face contact and then throw your other hand. After that, you go on and only think of the second punch etc etc out into into free flowing combos of pure speed; but start at the begining and hit the stages or you'll over think it.
