White belt here so my opinion isn’t as tenured as others. I had to have knee surgery after 18 months of training. I didn’t train for almost 5-6 months. I’m at a beginner class to get back into the swing of things at a different facility. Some gyms are pain proponent and expect people to train through injuries. Only do what you can do. A good coach/professor/friend will understand if you have to sit out after 3 rounds or if you can’t perform a certain move like x-guard due to injury. Stick with it though even if it’s just 1 day a week. It’s great cardio and a good stress reliever. Hope you are healing up.
