3 and half weeks post op for Left THR. Going well. Just a trekking pole when out walking to ensure no slips or falls. Swimming I km every couple of days. Arms only using pull buoy to keep legs still at the moment. 10 mins each day on static bike. Reluctant to go beyond walking, jogging seems a bit ambitious at the moment. Any thoughts or advice? I am a 70 yr old triathlete.
