When you say HIIT plus training, does that mean weight training? If not, then adding weight workouts on your off days would be good. Or, you can do yoga or Pilates; the right programs make me sweat! I have some of the 10 minute DVD's and sometimes do two routines at a time. Good old floor exercises work too.
Since you say low impact and focus on toning, I'm assuming things like walking, step exercise, dance or other cardio is not what you are looking for.
I do all my exercise at home, mostly using DVD's. They can be checked out of the library for free, or use the routines here on Spark, for free.
