HIIT
Alternating hard efforts and short rests, logged as one block of time.

How to do it
Setup
Pick the movements and the clock: hard work, short rests.
Steps
- Go HARD in the work windows – that is the "HI".
- Rest just enough to go hard again.
- Log the whole block as one session.
Common mistakes
Medium effort throughout: that is intervals, not HIIT; the hard windows must HURT. Sloppy reps under the clock: the timer never excuses form. Daily HIIT: it is a spice, not a diet; two-three doses a week.
Breathing
Hard in the work, recovering in the rest.
