If you use your breath to move energy... Do you use the in and out breath for different directions? Should you be consistent with this or can you vary?

For instance... If I am trying to raise my energy.. Should I only raise it on the out breath and hold it on the in or vice versa?

And the same for circulating energy... When bringing the energy down the front of the body does it make more sense to use the in breath or out breath?

Thanks,
Tom
