I injured my AC joint when a sempai accidentally disconnected from me during high fall practice. Sensei told me these exact words of wisdom! I was back training after 1 month. A bit gun shy I must admit.
Hi again.Hope you are well.The best advice I can give to you is this use your common sense and listen to your body.If by chance you get discomfort from whatever, do not force things.After you get past mid twenties you go downhill.If you wish to train for years you have to adapt.I am 75 I do not traiin like I did when I was in my twenties..High ukemi is a no no.for example.
Injuries take longer to heal [if ever].Your body has got to last you a liifetime,why be silly and ruin your knees /back /joints?Its just a game.Train seriously but with caution.Look after your own body and look after your partners body.as well.Joe.
