Whats te difference between counter tension andcounter?

Whats te difference between counter tension and counter balance in gymnastics in pairs when doing the balances. thanks

Counter tension is when gymnasts perform a balance which involves two or more of them pulling away from each other (or a piece of aparatus), where the weight is not even, whereas counter balance is when a move is balanced (like a sea-saw) or like when a gymnast performs an arabesque, the front and back of their body counter-balance one another.
