I have achy knees today - not a new thing and possibly more so after lifting days, especially after a lower body day (and yes I have good form, always am careful of that) But also notice them after tred mill runs too.
I sometimes wonder if my longstanding fitness routine is taking its toll on my joints. I even cut back on runs because of my knees and do almost half the daily steps now compared to 6 months ago - went from 21k+ steps a day to around 12k....
The other day a lady at church who was very into Zumba and Spinning tells me that they are the reason she lost cartilage in her knees and has arthritis in her back! And she warned me to be careful! Scary stuff thinking we could bring on our own ailments because of our fitness efforts!
Are we damned if we do, damned if we don't?
