A lot of people will ask me what their macro split should be. I work a little differently to a standard macro split. This video explains what I do and why it works for performance.
The macro split should be based on what you are doing and how you train.
Each macros have a different function and that function should be matched your your activity.
Use carbs to fuel activity and space protein evenly through the day.
For some people, protein distribution is more important than total protein.
