I'm considering a big increase in training frequency for a short period, like 2 weeks. My question: does a short term period of vastly increased training frequency have big long term benefits for a recreational BJJer? Or is it just extra training time - i.e. if I pack 9 weeks of training time into 2 weeks do I just get an extra 7 weeks of experience and then the benefits go away after a couple months (since I can't possibly keep up anything remotely at this level of frequency) - or is the value much more than this? More detail: I am a recreational BJJer with about 2 years of training who really loves BJJ. Currently I train 3 times per week most weeks (less the last 6 weeks or so - very busy at work and a couple injuries from training) for about 6.5 hours of mat time per week - when I train I usually do 2 classes back-to-back. I haven't competed yet although I do intend to at some point (probably very infrequently to be totally honest), pretty happy with my progress nonetheless and just enjoy training and learning/applying new stuff. I'm in my mid-30s and would say I have a very busy lifestyle (work as a physician with research/teaching/clinical responsibilities, time with family, church, other recreational stuff like computer games&watching MMA with friends). I would say my life is pretty tight timewise with little time left over and requires careful time management to keep it all balanced properly, but I kind of like it that way and it all works out pretty well much of the time. For the next 2 weeks I have a vacation, woohoo! Spending it at home to rest up and relax as I just finished a particularly intense work period. Other than spending more time with the family etc which will happen, I'm considering having an "increased BJJ" type vacation as well - maybe training for a short period like guys who are more life-focused on BJJ - maybe training 2-per-days, for 5 times per week (estimate something like 18 hours of mat time per week for each of the 2 weeks), and spending some time during the day doing some drills and looking at training videos. Potential benefits would be: having fun with it, getting a lot more exercise (needed after the holidays), making a lot of progress that would be long-lasting (would it??? or would the benefits disappear in a couple months). Potential downsides would be lack of benefit for time spent (???), and getting injured since I ain't as young as I do notice that random little injuries tend to bug me more than when I was in my 20s. So...thoughts? Anybody had periods where they really upped the training frequency for a short period, did it have long-lasting BJJ benefits?
