I try to do pretty much the same thing every day. There's a bit of time for balance/kicking drills, which is always the hard part because... well, because that's the hard part! And a bit of time for work on hyungs/kata, both practicing the forms (performing them) and thinking about what the forms are really encoding in the way of practical street self-defense (i.e.,
studying them). A bit of time for breaking. And a certain amount of reading/research, which includes time spent reading ongoing MT threads and initiating (or at least trying to initiate) my own.
As time has gone I, I find kihon-type line drills to be less and relevant to what I think of as `training the core' of TKD/karate. I think there's a virtue to doing flow drills, but it's not a crucial part of the activity. I try to visualize what it was that the people on Okinawa a century ago and earlier were doing, and keep that in mind. A lot of what they were up to would have been one-on-one combat training (note that I don't say
sparring here, because that word has too many of the wrong connotations at this point in the history of the MAs) and it's hard to simulate that when you're training solo. So visualization is important, and actually is something that can be worked on and developed: vividly picturing your combat movements in the contexts of a real attack. I try to do that in connection with my `applied' kata performance, as per
here.
All of this stuff I try to do every day, 7 days a week, for 40 minutes to an hour on the action side, and... impossible to say on the reading/research/studying side, but it's a
lot! So it's not always possible to do everything every day...
