Less than this and you’ll never burn fat
If you are serious about burning fat – it’s time to commit to a minimum workout of at least 30 minutes per session. Here’s why…
Once you have maintained your target heart rate for thirty minutes, your body will start using stored fat for energy and you will “burn” that fat. In the first twenty to thirty minutes, your body uses up the most easily accessible energy sources.
However, if you are able to maintain that heart rate for longer, you will be able to burn fat and see the changes you are looking for from you workouts.
The science behind the 30 minute workout
One common misconception that leads to confusion about weight loss is how carbohydrates and sugars relate to fat and fat burning. When you consume carbohydrates, they are broken down into sugars called glucose and glycogen. Glucose is used by the brain and heart for energy as well as maintaining your body’s blood sugar levels. Glycogen is stored in the muscles and liver as a source of energy. When your body has more glycogen than needed in the muscles and liver, the glycogen is transformed into fat.
Glucose and glycogen can both be broken down by your body for energy without the use of oxygen. They are the energy source for exercises like sprinting, jumping, and squat thrusts, which are quicker activities. In order to use the fat that your body has stored for energy, it is necessary to work out for longer periods of time while consistently maintaining your target heart rate for burning fat.
