For those of you who are unfamiliar with the term mitochondrial biogenesis, it means the generation of new mitochondria.
If your a walker 30 to 45 minutes a day of walking will do. If you’re into more intense cardio like HIIT or circuit training, that will work as well.
In addition there are supplements that can help improve the generation of mitochondria. They are mentioned in my previous post 3 Ways to Enhance Your Mitochondria.
