Why

I recently got my fourth DEXA scan over at Live Lean RX and the technician coaches me on nutrition and other aspects of living lean.

One thing he always mentions is training for Vo2 max. This increasing your Resting Metabolic Rate (RMR) aka your metabolism completely at rest.

The RMR test has you fast and then exhale into a tube for a few minutes and checks the levels of the gases in your breath the Vo2 max test is the same but with you working out super hard.

How

Raising our Vo2 Max levels involves us getting our Heart to maximum BPM just for a few seconds just like lifting heavier and heavier weights just for a bit will make you stronger.

In Watch OS 9 Apple introduced the heart rate zones screen in the Workout app.

This allows us to get a visual indication of when we hit the sought-after red zone.

What

I decided to use a rower to get a full-body workout, it took a bit longer than I expected and I pushed the rower to max resistance but lowered it after I started to get gassed.

Standing up after the workout I was super shakey and for the rest of the day had a runner's high.
