If in fact you're talking about the BOSU Balance trainer (pictured on the
right) and not the BOSU Ballast ball the answer is pretty simple.
The "pro" or commercial model is the model of the BOSU Balance trainer you
should get as it's made to last through hours and hours of heavy duty gym use.
Even if you jump up and down on it for 2 hours a day 7 days a week, 56 hours
a month, 672 hours a year you will not even come close to wearing it out.
All the videos on the BOSU Balance Trainer Exercise Videos
on AskTheTrainer.com were filmed using the
BOSU Balance Trainer PRO.
Another difference between the models is the warranty. It will not
likely matter to you if you're using it at home, but the commercial version of
the BOSU comes with a longer warranty as it's expected to last longer.
The only reason you should consider getting a lower model is if the
difference in price is significant to your budget or maybe you want a smaller
version due to lack of space. If you're looking for versatility,
durability and high quality product that will effectively last for years, pay
the extra couple bucks and get the professional/commercial model.
