I am female, 31, mesomorf build and I adore workout (4-5 times the week), generally I am toned and my weight is normal. My goal is lean but strong muscles. I swim regurarly (my favorite sport since child) and I would like to workout at home too, but because of arthritis I avoid jumping lunges, planks and high impact cardio. Is there a specialised program for weak joints in intermediate level? Thank you.
