Hola! Like you, I also workout at home, and with minimal equipment. I also started out with Jillian Michaels (I did the 30-Day Shred for quite some time), but I've moved on from her after discovering other things/instructors I like better. Now I use Leslie Sansone's Walk at Home DVD's (there's a ton to choose from, but all are good and around $9) and workouts from a few exercise games. For the purposes of this response, though, I'll assume you don't have a game system and/or the inclination to spend the cash on the games.
I like Zumba (I'm sure you can get a DVD) although I'm pretty new to it - the moves can be a bit confusing, but as long as you keep moving, I figure it's all good. As far as the other stuff, there are so many exercises you can do at home that are effective and free - mostly it's a matter of using your own body weight for resistance and running/walking in place or just taking a few steps in alternating directions. But I digress. You can use your weights to do a variety of lifting moves - squats, bent-over rows, etc. Push-ups, planks/side planks, crunches, reverse crunches, lunges, side lunges... The list goes on and on. You can check out sparkpeople.com (essentially FitDay's competition, far as I can tell
) or youtube to see these and many other exercises demonstrated.
Be easy on your foot - better to take a day or 2 off than to further aggravate it and not be able to do anything for a week or more. I speak from experience. Feel the burn, not the pain!
Hope that was of some service; I'm sure others will chime in as well.
