I meant to respond sooner but work often blocks my access to this website, and increasingly :/

Anywho, an odd thing I've noticed with WHM is that on mornings where less in general is bothering me (e.g. it's warm and sunny, not sleep deprived, nothing is generally pissing me off) my breath retention time is longer. Have you noticed that too?

Squatting + WHM unsurprisingly worsens my breath retention time, but that's unfortunately what a sedentary lifestyle does for you, despite exercise :/
