How to Measure Interval Training Intensity?
What kind of gadget do you need? Is it different for 1) cycling, 2) running, and 3) swimming?
The other question is: Do you know a gadget that beeps after a user-set time (like 1min) and again after 30 seconds, etc.
i like to start a cycling, running and swimming Interval Training cycle/program, but i don't know how to Measure Interval Training Intensity.
