1.) Hagoromo FedExes everyone some chakra for Christmas. 2) Everyone now has a small bit of chakra, the purpose of which is to link their hearts together. 3) They say thanks, but no thanks, Hagoromo, we're going to link our spiritual and physical energies together to make a large quantity of chakra. 4) Now they fight with that large quantity of chakra. The chakra that was amplified was that original small bit of stimulus check chakra that Hagoromo gave them.

This is just my interpretation. What are you disagreeing with?

As far as I remember, Madara noted that by mixing spiritual and physical energy, people increased their own chakra.
