Push-ups on the BOSU platform are very comfortable on the joints compared to
push-ups on the round surface of a single BOSU. Due to the distance
apart of each grip the upside down BOSU pushup targets the triceps and anterior
deltoids more than the chest as well as the core. The core is challenged by the
wobbly upside-down BOSU. This exercise can be progressed by wearing a weighted
vest. The upside down BOSU push-up is perfect to use towards the end of a
workout which involves the chest and/or triceps but if you are just beginning
you can use it as one of the first few exercises during a BOSU ball workout.
