Significance of THR
If your heart rate is too high, you’re straining. So slow down. If it’s too low, and the intensity feels “light” or “moderate/brisk,” you may want to push yourself to exercise a little harder.
The target heart rate is extremely significant because it is at this level that you actually reach the stage where body starts utilizing fat as a fuel. Reaching a certain limit of your target heart rate enables the body to start mobilizing the stored fats and use them as fuel to continue exercise. That is what we actually want to achieve from exercise, right? We wish to push off the flab (fatty tissues)
During the first few weeks of working out, aim for the lower range of your target zone (50 percent) and gradually build up to the higher range (85 percent). After six months or more, you may be able to exercise comfortably at up to 85 percent of your maximum heart rate.
If you have a heart condition or you’re in cardiac rehab, talk to a healthcare professional about what exercises you can engage in, what your target heart rate should be and whether you need to be monitored during physical activity. This will also help you to choose the types of physical activity that are appropriate for your current fitness level and health goals, because some activities are safer than others.
Should you go slow & steady?
Some people start off with vigorous exercise right from the beginning of the weight loss program to get faster results but that is a wrong approach.
For instance , if you decide to start running for fitness then it is wiser to start slow. Some individuals run at a very fast pace and reach a point of complete exhaustion equally fast.
Rather one must try to run slowly (at least 50% of Target heart rate) and maintain a steady pace for a longer time period. This ensures that you allow your body to sustain exercise longer and start utilizing fat as the energy source for exercise rather than just carbohydrates stored as glycogen.
