I realize you already made your purchase, but just to chime in…I definitely agree with Adrianne – both are awesome. I teach a large quantity of classes using both pieces of equipment and I would say on average more people are actually intimidated by the BOSU as they feel loss of control if unbalanced. Whereas they feel more comfortable using the TRX (with proper instruction) because they can always change their body angle, stand tall take a break, etc. If you can get both – I recommend it – the TRX is a HUGE draw for clients! Best of luck!
