High intensity mental training>?

research shows that high intensity phisiological training is as effective as long endurance training. Albeit tking 10-25% of time.

Can mental training work same?

short term high intensity self regulation exercises?
short term high intensity meditation etc.?


Much more practical. I hold that part of hte reason most ppl do not do these is because the cost involved. Cheaper methods may lead to much more ppl practiciing these.
