Somehow my iPad lost the function “mention someone”, so consider yourself tagged. . Either one of you do so such strenuous exercises in the pool, you must be in great shape, and / or in a very good pool/fitness center. The one I joined did a super job of designing knee rehab exercises, throwing in balance and upper arm strength workout, but in the end for me I worked up to basically swimming. Distances. Mostly 800 meters, a few times 1000 meters. Good aerobic workout, loosening up knee, and life is good in the water. This center also offers a great variety of water exercise classes, but the timing - mid morning, but I’m already going places then - does not work for me. In SC. Where it gets pretty warm, pretty soon, both in the day, and in the season. So the mornings from now on out are for yard work. And planting. And pulling weeds. And harvesting - first batch of sugar snap peas 2 days ago. Spinach, lettuce, and radishes, of course. (Just in case there are gardeners out there). Who also can’t kneel well. Oh well.......... sorry to get off subject.
