Hi just tuned into this message board. Not been here for years. I actually just train. I don't give much thought to age and would be disappointed if my fellow club members made special allowances for my age ( 65), the day may come when I do have need of special consideration and I'll accept it gladly. I'm a Shukokai Shitoryu Dan grade but have gone back to basics last October 2018 to start Goju Ryu. I've never been flexible, so started from, literally, a low base, so not particularly noticed any decline. I do lots and lots of supplementary training weekly including Grit x 30mins which is an extremely arduous cardio work out, circuit training x 60 mins, also variously some weights, kettlebell and " running" ( becoming a problem). I do two GoJu sessions weekly, 2 hours and 1 hour I am starting to feel really heavy legged, not sure whether it's age or i'm overtraining ? I've decided to pull back on the " leg" stuff ( other than karate) and see if my performance improves. Any thoughts ? Cheers
