There are many types of shoulder repair surgery..... you could have tendon to bone repair or tendon to tendon repair etc. the typical repair could be healed in 4 to 6 weeks but your body creates scar tissue in response and that tightens everything up. That’s what therapy is for ,,,,
If you overstretch your tendons when they are not ready,, you could be fine or you could be torn up again. when I’m carving, it def stretches my whole body to extremes that would be an issue for a compromised joint....
be smart
good luck
