I was back in the gym at 10 dpo doing treadmill walking with incline and bodyweight lower body exercises such as squats and lunges. I’m now 18 dpo and I have been using isolated leg machines, resistance bands and the smith machine for legs. I just make sure I don’t hold on or do anything which will engage my chest muscles. I get all of my cardio doing treadmill walking using the incline to increase the intensity. I know advice is no gym for 6 weeks but I personally think if you are sensible, avoid upper body until you are 6 weeks post op and don’t do anything which causes pain it is better to keep fit and active; it was also driving me mad as I was training 5 days a week before my op. My pain and mobility improved dramatically as soon as I started back at the gym xx
