Seasons.

I have heard so many different things about what is good for you and what is detrimental when it comes to your training, in the end you really have to take what is said with a grain of salt and decide what best suits you as an individual.
Take push-ups for instance, I like doing push-ups and static core training, but many people tend to say they can make you slower, thus they are not good for Karate training.
Personally, however, I like them, and with a mind towards fast-twitch and maintaining posture, I don't really see a problem with doing them - especially since there are so many creative ways to perform a push-up.

In any case it really doesn't matter, you will find what works for you, what you like to do, the key is to stick with it, to get a routine going and to build on that.
With me, it always centers around Sanchin Kata, it begins and ends there; ever since that first experience I had with Kris Wilder in my old basement training room I had sought to really understand that particular method.
Again, however, there are some differences, though not many, you have to find your own middle ground.

Too much training is a detriment, too little training is not going to do you one bit of good.
There I go with my own warning of what is 'detrimental' and what is not, in some instances it is apparent mainly due to the way the body works, but in other cases it is just hot air.
You should trust in your chosen guides on this path, but you should always trust yourself as well, listen to your body.

I do five sets of twenty push-ups every other day, but I do them every day. I do some Hojo Undo twice a week, and I work Kata and Kihon every day. Early mornings work best for me, as do evenings - beginning and ending with Sanchin, working Sanchin three times every single day.
Static methods work great as well, I remember a video Shinzen shared on facebook about an old Chinese method of exercise that consisted of standing in various postures for extended periods of time, just standing, sometimes incorporating walking, just walking.
The main thing was in the focus, the mindset, and the posture. With the goal of developing the mind and body along the lines of a tree, with strong trunk, and strong roots, I see nothing wrong with this (though it does not need to be nearly as complex, one could easily say, just stand like a tree).
Diet is important too, but I won't harp on that too much - this is getting to be borderline athletic-type stuff here, perhaps not.

In either case there is a rhythm, and you must find your own rhythm.
