Hi Cassandra, Thank you for reaching out to the Grokker community. You did not mention if any of the surgery were recent. If so, please do not self diagnose or use Dr Google. Please follow the advice of your occupational therapist or your physiotherapist. If the surgery happened some time ago, then gently does it. As well as the gentle videos listed in here and others in Grokker, you might like to reach out to Sam Skelton, one of the Grokker experts here as his qualifications may assist you.
I have attached two core videos for you to review and if you search "Core" on our website it will bring up more core videos and also a 4 Week Core Program with Sam Skelton. As with all exercise after surgery it is best to speak to your doctor who can recommend when you should start exercising again.
