Yet with this being said, some people believe that they should perform
low-intensity workouts even when they could be performing more high-
intensity workouts.
That is, instead of jogging for 20 minutes with their heart at the top end
of their aerobic zone, they opt for low-intensity jogs that barely break a
sweat.
Low intensity workouts simply don’t lead to a faster metabolism; they
can’t. Remember, as we discussed very early in this book, metabolism is a
process.
And that process is really one of two types: taking energy and making cells
(anabolism), or breaking cells down to make energy (catabolism).
If you don’t achieve a high-intensity workout, your body can’t tap achieve
catabolism; it won’t need to. And the only way your body is going to go
and break down existing cells is if it needs to.
So keep this in mind as you exercise, either at home or at a gym. Low
intensity workouts are better than nothing at all; and they may be
necessary if you’re recovering from injury, or just starting out on the
exercise journey.
But once you reach a level of basic fitness, only high intensity (aerobic)
workouts will make a difference in terms of your metabolism. High
intensity workouts force your body to find energy to help you maintain
that level of exercise; and it does so through catabolism.
