Hi Colin, oh, that's great! Say, when you get into it more and if you have any questions, I would be very happy to help if I am able to.

For instance, on the lower back excercises, there was one particular excercise that helped me greatly the time I injured my back 4 years ago. And yet, the last time I injured my back (2 years ago), that excercise not only did not help, but I just was not able to do it at all.

In other words, it will take a bit of experimenting to discover which excercises will work best for you.
The routine I use now is great and is easily done in the evening, maybe 4 or 5 times a week (I use only 3 of the excercises)

BTW, I reinjured my back two years ago because I got lazy and stopped with the excercises altogether. Never again! :-)
Best regards,
RC
