Is it chronic cardio to do the elliptical 5 days a week with some yoga on the weekends? I don't feel burnt out at all and enjoy doing this cardio for energy in the mornings. I usually do level 12, resistance 4/5 for 45 minutes. I have not actually noticed any changes in my body, in fact I seem to lose weight when I don't do any cardio at all so that makes me think I am potentially stressing my body?
