hi,
i was a pro soccer player many years ago now however i was still very active training uaually 2+ hrs per day up untill i was diagnosed with itp in january this year with counts usually under 5 all i do now is walk at a moderate pace 3-6 miles per day i am 34 and have 3 kids im obviously different from your son as he is on the way up and im very much on the way down and training is very important to him ,but i truly believe giving your body a chance to recover especilly with low counts has to be much safer than pounding it ,at his age im sure he will not lose to much with skipping training at these times ,i'd rather be less fit and safe . Hope all goes well
