I work at home and I bought an elliptical training machine. So I can train as many times per day as I want. It would be comfortable for me to work for about 30 minutes and then make 5 minutes break for training. My work day is about 8 hours, so I could make 16 breaks and it would be 80 training minutes per day. I understand that short trainings not so effective as long-time trainings, but how critical is it?
For example calories indicator shows me that I burned 60 kcal per 5 minutes. So will I burn 60*16 = 960 kcal per day or short trainigs will negate this effect? What about endurance training? Heart training? How much less effective such short trainings will be in comparison with long time trainings if they are equal in time?
