Your wrestling feels more exhausting and not up to the level you want, because there are lots of moves and exchanges you do that serve no to little purpose.
I want you to slow down and start paying more attention to where your palms are,
and how engaged they are.
One of your main challenges when it comes to improving your hand fighting is the pace at which you practice and noticing your hand placement.
Spend your next few sessions paying more attention to where your palms are and how engaged they are.
Eliminate those redundant movements and see how quickly the quality of your hand fighting improves!
