Query: Good simple workout for indoor routine

I'm 62 and have had two major abdominal surgeries in the last 10 years and no skinny Minnie. This is a good way to regain some abdominal strength. Yes, it will tire out the true beginner, but that is how you regain your muscle strength. She does show how to do beginner positions and the more advanced positions. Do the beginner ones and work your way up. You will feel refreshed when you are done.
