No problem! And at my gym, I can schedule a one-time session to work with a trainer, so that might be an option...
The most important thing is to listen to your body. I've got arthritis, so I'm quite aware of my joints and when things don't feel quite right. There's a "wow, this is hard work" kind of pain and there's "oh, my body isn't supposed to move this way; something's wrong" kind of pain. Know the difference and don't be afraid to stop and ask for help. If there are others working out when you're working out, keep an eye out for the ones who seem to know what they're doing and who are using good form. You could always ask one of them if he or she could watch you do a rep or two to make sure that you've got the form right. I've done that and everybody is more than happy to help. Once you're in the gym for a while, you start to see the same people and can probably get an idea of who would be willing to help out.
Oh, another thing...use the search function here and look for the posts about some of the exercises. Lisa~ usually posts great links to reliable videos for the exercises. You and your husband could watch the videos and then you could try the bodyweight versions at home so that he can watch you do it (with the memories of good form firmly in mind).
Good luck! I'm on Stage 3 and LOVE this program.
