I have been doing the 100 days of qigong ( day 41! Yeah!) and am feeling more energetic and stronger, plus have lost a couple of pounds through doing the qigong with bent knees. I am feeling strain and pain in my knees and don't want to be damaging them and wonder if I should push through the pain,continuing with bent knees and hope that the energy moving through will clear the pain, or should I back off? Does anyone have experience with this? I'd be grateful for some feedback.
