It is important to rest.

One of my own follies is over-training: my training reaches a peak where it feels fantastic overall, but I start having problems: tiredness, stiff neck, migraine...
These are signs that I am doing too much.

I pare my routine back to the absolute essentials, and give my body time to recover.
My energy returns and I am ok.

This sounds easy enough but it is hard to let-go of the extended training, hard to do less.
The urge to hold-on is strong, but also harmful.

When I was 25 my doctor told me to choose whether I was going to focus upon kung fu, yoga, running or cycling.
I was doing all 4 activities simultaneously and pushing it.
The doctor said that you cannot train like an olympic athlete every day without it taking a heavy toll.

I chose the kung fu because it is sustainable and mild on the body.
But only if the training is moderate...
