What Zone 2 Actually Means Zone 2 is the highest effort you can maintain while still speaking in short sentences. It builds aerobic capacity with low recovery cost.
Most adults can start with brisk incline walking, cycling, or rowing.
Programming for Busy Schedules Aim for 120 to 180 minutes weekly in two to four sessions. Add one short interval session if recovery and sleep stay strong.
Treat weekly volume as the main lever. Intensity spikes are optional.
How to Progress Increase session length before increasing speed. Keep nasal breathing as long as possible to avoid drifting too hard.
Re-test pace or power every six to eight weeks to confirm progress.
