one minute turn around and run back. "1 in/1 out"
For 1in/1out, set watch to continuous countdown mode for
one minute. It will beep every minute in this mode. Start
run and make mental note of location at turn around.
Push hard enough that you cannot make it back in one minute,
i.e., done right you come in "late."
2. Pick tough three rep load. Hold for all six sets.
3. Try for same one minute "outspot" on second
run. Again record time "late" on return. Compare
to first run.
4. If you don't want to run substitute 500 meter row or
5 minutes stairclimb or 5 minute cycle.
