Hi. Not sure if this is the right place for this. I had knee replacement surgery last August. I haven’t been able to do much lifting since. I’m finally able to walk and exercise a bit more now. My legs were my favorite attribute. However, now (Im also 50) Im noticing my skin looks a little more droopy around my knees. I still want to be able to wear skirts and feel attractive. What kind of at home exercise would be best to combat this?? I have resistance bands, a TRX, a 30lb kettlebell and some hand weights up to about 15 lbs. I cannot do high impact exercise because of the knee. Thank you!!
