So sorry about your knee pains, truly I used to held the believe that only women from 50s can develop this type of sickness, but thanks for the enlightenment. Just continue with the exercises, but I'll advice you mostly do aerobic dances and yoga it will really help, good enough you like dancing, Hahaha 🤣 then portion your meal very well, eat more fruits and veggies couple with drinking calcium drugs then you will see good result in now time. I wish you a speedy recovery!
