In 2019, BOSU came out with a new product. They are called BOSU® Pods and they look like mini BOSUs. I noticed them when shopping for something else and thought they might be useful during driving trips. A regular BOSU takes up too much space. I took it along a few times during knee rehab in 2012-13 but have only been using it at home in the last decade.
Here are a few videos using BOSU Pods. I'm unlikely to do Kaitlin's full workouts but found her videos good for ideas of how the Pods can be used.
