When I did the first DVD a while back, I remember feeling like my BOSU was inflated too much. So, I deflated it a little bit and that seemed to help. Today, I did part of Mindy's section and my BOSU feel *too* deflated. Almost like the surface was so unstable that I was concerned about rolling an ankle. I also had trouble going on and off of quickly because there was good traction between the rubber and my shoe.
Granted, I don't do classes or teach so this was my first experience doing cardio per se on the BOSU so it could just be a lack of conditioning on my part. Have you noticed discrepancies on the inflation per workout?
