Functional.

[Chris Nagel]

Functional training, what is it, your thoughts on it and solutions.

The body works all or nothing, you train movements not muscles.

That said, I think 'Functional Training' should be about improving movements. For instance in boxing, these would be exercises that improve footwork, punching, and responsiveness. Using a bit of kit like elastic cords/bands, it can be set up to improve specific movements when used properly. This way a fighter's body can 'feel' which adjustments to make, rather than depending on the coach to constantly tell them which adjustments to make.
