Compare a short-bout week with one longer session on time, what each is evidenced to improve, and which you would keep.

This tool gives general information based on the research summarised in Stairs as Exercise: What Short Bouts Actually Buy You. It is not a medical device, does not diagnose, and does not replace advice from your clinician.
