massage once a week sounds perfect
... i also know some professional football players who get a massage every week, and i have no doubt that in those cases it's needet that often. but i also know some professional ice hockey players who never go to get a massage (because it's so painful)... and i can't understand how they survive and train without any massage at all.
i would like to have massage more often than four of five times a year, but i'm not sure if i really needed it more often. and ofcourse it's a question of money, too. in helsinki there is (at least) one massage school where students do massage. it's not free but it's a bit cheaper. i have been there few times, but those blokes couldn't do it very well, so unfortunately it was more like waste of money. that's why i nowadays prefer to pay more, when i know that the massage i get is really good - it's sports massage, and it lasts about 2,5 hours
i like sports massage, although it's quite painful for me. not all the time, but most of the time. i like shiatsu as well.. it feels better when it's done, but i don't find it so helpful, because the effect doesn't last that long (in my case).
well... however... all kinda massage, anytime, is one of the best things in the world
