With the CorMax range and CIP training nearly every product and exercise will challenge your core.
What other training tools works your abs when you are not even working on your abs. None!
As soon as you exercise with any of the CorMax range the sloshing of water pulls and pushes you in every direction igniting your stabilising & core muscles instantly and working them to the max.
Actually the less water you have in the CorMax products the harder they are to control.
Conversely the more water the heavier they become and more stable.
High intensity, why?
Because they are the best workouts to deplete your glycogen (stored sugar) in your muscles.
When you’ve depleted your glycogen, your muscles need to replenish it, so the sugar you consume gets used up and stored as glycogen rather being stored as fat.
