This carbon dioxide table is structured identically to class 4a, however each breath hold will be 2 minutes instead of 1.30, making it a slightly more challenging practise.

Here is a breakdown of this co2 table:

Breathe: 2 // Hold: 2

Breathe: 1.30 // Hold: 2

Breathe: 1 // Hold: 2

Breathe: 0.30 // Hold: 2
