I suppose it depends how you define cardio, but I believe cardio, particularly brisk walking and running is very good for the brain and for maintaining cognitive abilities as you grow older. It also helps get rid of depression.It may be that resistance training is as good or even better. I don't know.
Is HIIT/Tabata considered cardio?With regards to general health (disregarding fat loss) I feel much better when doing some HIIT each week, rather than just lifting. There are health benefits outside of fat loss that need to be considered.
