The tip of the wave can be sharp and as such we tend to avoid it.
Fighting can be a clash if we ignore the tip of the wave in our training.
Here is a hold which is not fun in the beginning but builds a lot of staying power and connective tissue strength and that allows us grace and power in conflict application and in life.
Place yourself in the push up position and on your fists.
Lower yourself so your elbow joints are at ninety degrees and your wrists are straight as your back.
Breathe and count your breaths until your reach 300.
That is it.
Repeat this a few times a week and modify for your needs as you wish.
One modification I enjoy is using one hand at a time so the body learns to balance more and spread the needed tension throughout.
The work is a reward.
