When visiting my parents I have access to their stepper.I only visit them every now and then - lets assume once a month I can use the stepper.
I don't have a specific goal, I normally ride bike and run as main cardio-activities, but on the stepper I don't necessarily try to support those activities, it is more like a welcome variety.
I tried to do something interval-ish today, I wonder if there are any good guidelines or recommendations how to make use of that machine. The time I spent and want to spend is 30 minutes; I normally do one session between weightlifting and sauna.
As an example, the intensities of the exercise I did today:
The intensities translate to a number of 20cm steps per minute:
lvl steps 14 138 10 104 6 69
