All-out sprints for 20 seconds just 2 times
That’s the whole workout
It sounds too simple to work…
but those 40 seconds push you into Zone 5
(your max effort)
That’s the point where your body is forced to adapt
not just “burn calories”
So instead of spending 45 minutes trying to get a result
you create a stronger one in minutes
You don’t need more time working out
you just need the right stimulus
