Yeah it's just a sales ploy LOL. They will do exercises for you with or without a board and asks if you have one or not before you start, and in all honesty I am on Day 11 of the challenge and only had a couple of activities with the board.

You definitely feel it the first few days. Omg I could hardly walk LOL. You do 2 days then they give you a day off, 2 days, day off etc. I've also been watching what I eat during the time as well and have dropped a kilo. I was doing it before christmas too, until Day 10 when I tore a tendon in my ankle from side lunges. So now I just cross out them I had lost a kilo in the first 10 days prior to Christmas too, but put it back on over christmas when I was laid up cause of the ankle LOL.
