I'm 5ft 7 and 205lbs, I can definitely notice that I'm heavier when I move around and it's more difficult to move around than it used to be even with all my efforts. I also experience mild knee pains that I'm hoping to overcome through muscle building.
Tight muscles can also be a factor in knee pain (muscles don't have enough flex to make good shock absorbers). So don't neglect stretching and maybe consider some massage.
