All weight is underside
My knees and hips complain less when I do more of the reasonable stuff (martial arts, hiking) and less of the unreasonable stuff (working on decks, terracing the yard, etc.). I like the way they think.
My knees complain whenever I stand up from a chair and every now and then my hips make themselves known when I am simply walking. Can't work on a rowing machine, can't do squats, even have trouble on an stationary bike, but doing Yang style taijiquan, they leave me alone for some reason,
