Yea @twoinanddone. We have a PT come to our house twice a week (used to be three times) for the last 10 years to do core exercises for my back (after a month, ShawWife decided to join in). Could I do these on my own? Absolutely and I do sometimes when I am traveling. But would I do them on my own two to three times a week? Unlikely. And I was able to defer back surgery for 10 years as a result.
