There’s so much research to show that staying active keeps you you healthy so it’s your job to FIND a way.
I was told in 2013 that I couldn’t run any more, if I wanted to preserve te health of my failing knee. I struggle to competitive cycle any longer and gave up triathlon. Did I give up completely? No. I swim long distance, I row, I still cycle recreationally and now full time train and inspire others to achieve their fitness goals.
There is no ‘I can’t’. It’s just a case of finding out HOW CAN I.
