Endurance training has significant benefits. It:
- Improves mitochondrial function
- Allows your muscles’ ability to use fatty acids as fuel
- Raises the level of energy output before switching to lactate
- Protects against metabolic dysfunction
- Increases aerobic capacity
The most effective way to train for improved endurance is long bouts of easy, steady-state exercise. For the best results, you must:
- Stay below your lactate threshold i.e. zone 2 training.1
- Spend at least 20 minutes at a time in zone 2.
- Accrue 3 or more hours a week of total training time.
Different models of activity have varying numbers of zones and different criteria that define them. Here, what we’re looking for is that your working hard enough that you can feel the exertion but you can still carry on a normal conversation while doing it. ↩
