That makes them extremely portable, and it also means they won't take up a ridiculous amount of space in your house or apartment. But that's not to say they won't cause a significant amount of burn during and after your workout. I can attest to the fact that they increase the intensity of a plank, that's for sure.
Did you happen to notice the price in my Target photo above? $29.99 is a super steal in my opinion, especially since the kit includes two full-length workouts. Now, I haven't actually purchased a set for myself yet (come to find out, we have a set at the gym) so I can't say for sure whether or not those workouts are worthwhile. But that instability factor...it's good. Especially in terms of your core. Remember that whenever you stand on an unstable surface, you immediately call upon your core muscles to help you find balance.
I found this video online, perhaps it's similar to what comes in the kit:
Question: Have you ever used a set of balance pods? What's your opinion? And speaking of balance, do you consider yours to be good or bad? How do you know?
