Swimming laps helps and I have done that in the past. The water therapy I deal with now is in a pool, 4-6 feet deep, 94 degrees, with 5 lb ankle weights. I do a workout with stretching, leg lifts, exercises in a chair, running motion in deep end etc…. Workout takes 30-45 minutes, then I do 45 minutes in the gym at the facility. The PT who works on me is a good golfer and a member of my club so I trust him. I am finished lifting heavy wood, putting it on the splitter and stacking. Splitter is actually on FB Marketplace as we speak
