This is the same pad I used at physical therapy and I liked it so much I purchased one for home use. It is sturdy and durable. You can challenge your core and balance in different ways. I use it to stand one 1 foot to improve balance. I also stand on it when doing other exercises to improve my core, since it makes your body react in a subtle, dynamic way when doing biceps curls, etc. You can also use it for step-ups, which improves proprioception and balance, although it is not a very high step.
