Put the gear in the water first, Don the gear in the water to keep the weight off.
When my father had his hips replaced...not at the same time which he regretted later...he found that he wasn't healing very quickly at all. I recommended he get in the pool and swim laps as he felt comfortable to do, and it cut his recovery/healing time in a big way. His doctor now recommends swimming to all of his patients (that can swim) and has had great results. For those that have had replacements done, has this worked the same way for you too? I figure non-impact, total body as swimming is has to work well for the recovery effort. My only concern would be for the extra weight out of the water as we gear up.
