There are about a billion of them on Amazon and I don't know which one to go for, so please help me choose one based on the following criteria:
- I'm currently fairly fit, so I can manage something that's quite intensive, but I do have clicky knees so stuff like squats are a bit difficult.
- Absolutely nothing that involves dancing. I've tried the Zumba DVD, and I just can't do it.
Thanks in advance for your suggestions!
