The Myth Of Zones
For weight loss purposes, the theory goes, it’s counterproductive to work too hard; instead, you’ll optimize your fat loss if you take it easy and work out less intensely. According to this argument, low-intensity training forces your body to burn more fat as an energy source, while high-intensity cardio work burns more sugar and less fat.
Sound too good to be true? It is.
Here’s the real deal: Higher intensity exercise burns more calories from fat overall. Its also harder for the body to adapt to. Low intensity efforts quickly become the norm for your body and it adapts and actually burns less calories over time.
So push yourself, strive for new goals and keep the body guessing by mixing up your routines and pushing hard. You will be rewarded!
