I hate to bring up an old thread (sorry, mods!), but am trying to use the BOSU at my gym and am in need of help!
I started out doing my dumbbell arm workouts on the BOSU. I was used to standing on the blue side (quite wobbily, I might add) when I noticed two other people (accomplished lifters) using it by standing on the black (flat) side. So I concluded that I was doing it wrong and started using the black side. I've been doing that for months. I've inched my feet in closer and closer to the middle to try to make it harder for me, but I can now practically do it with one foot in the air and no wobbles. I'm thinking it needs to be harder for me to actually be using my core muscles, so I decided to go back to the blue side.
However, when I tried the blue side, I wobbled all over the place and literally fell off three times over the course of four sets. Am I doing it wrong? Are you only supposed to use the flat side? If so, how can I make it harder?
I love the idea of the BOSU, but am obviously untutored on how to use it properly. Help?
