A quick update - I'm now 5 weeks post-op, doing PT 3 times/week and home exercise on the off days (mostly just nice long walks and stationary bike). I did, however, get back in the pool today for a swim. I'm darn sure not in race shape, but I managed moderate freestyle/butterfly sets for about 45 minutes. No flip turns, no jammers, but it felt really, really great to be back in the water.
If there are any swimmers out there, I'd love to hear about any workouts that you used following THR, when you started flip turns, etc. Thanks!
