Back to Zumba with Turbo Jam Schedule?

So, next week, my ZUMBA class starts back up. The woman who runs it holds it in a School Gym so, it is only active during the school year. Next week starts my second 4-week cycle of my Turbo Jam schedule.

I am trying to decided if I should add 2 nights a week of Zumba with my schedule for my Turbo Jam. I know every added burn is great but, I also dont want to over-do it just yet as my knee has been kinda tender the past week. I LOVE Zumba but I am really loving getting into this Turbo Jam too.

HUM...such decisions!!!! :-)
