In a nutshell, smart training that leads to results is based on three variables:
- Frequency: How many times you exercise during a period of time, for example per week.
- Duration: How long you exercise at a time, usually counted in minutes.
- Intensity: This one is a bit more complex - and that's where your heart rate comes in.
Your heart rate is one of the best indicators of how hard your body is working during training. Instead of trying to 'guesstimate' the intensity of your workout, your best bet is to rely on your heart rate which is a trackable number, just like frequency and duration.
