If you are doing 30 minutes - it is 30 minutes no matter how many exercises you are doing within that time. God Bless

Thank you for the answers. I was just curious, it doesn't really make much difference the time. If you look up pulmonary rehab or lung exercises in the search engine, a bunch of exercises will pop up. One I use is Donna Wilson from the lung institute. Jean. the exercises I do while cycling are arm and breathing ones, the others-standing, with weights and tai chi I can't do with cycling.

For a total of 600 calories. If you burn a total of 600 calories while doing all simultaneously the the total effect is the same as an hour . However, if you don't maintain the same intensity while doing both as what you do when done separately then the effect is less calories burned. That's what I think anyway.

lol 30 minutes isi 30 minutes. I use Donna Wilson a rehab nurses exercises on utube

Agree....but I'm curious about what internet exercises you were able to do while cycling.
