HIIT

HIIT (High Intensity Interval Training)

Prologue:

WTF is it?:

HIIT or High Intensity Interval Training is a form of cardio, it involves intervals of varying intensities, with some of those intensities quite high.

A typical HIIT routine will involve some bursts of "all-out" training followed by periods of lower intensity that allow for active recovery

A HIIT can range from 20-60 seconds of high burst intensity followed by 60-90 seconds of active recovery. (low intensity, but still working out)

The Switch:

I've begun switching from LISS (low intensity steady state) to HIIT based work outs. There are a couple reasons, some personal, some scientific.

Personal:

1) I get very bored when doing even power walking on the treadmill, it's mundane.

2) Tired of trying to figure out what to do while walking as to not let my mind wander and focus on the time rather than the work out.

3) So... boring...

Scientific (Pseudo):

1) Burn more calories in less time

2) Burn more subcutaneous fat than LISS

3) Burn LESS muscle mass than LISS
