Examples of calculations
Easy training - 60 kg, heart rate 110, time 40 minutes
With such effort, you will burn about 180-200 kcal. This is the equivalent of a small candy bar. The heart rate indicates light activity, good for recovery and improving circulation.
Moderate training - 75 kg, heart rate 140, time 50 minutes
In this case, you will burn about 400-450 kcal. That's about the size of a medium-sized margherita pizza. The activity is in the zone that promotes fat tissue reduction.
Intensive training - 90 kg, heart rate 165, time 60 minutes
Here you will burn up to 700-800 kcal. This is the equivalent of a large fast food set. Such a load improves performance, but requires good condition and preparation.
