Reach Your Aerobic Threshold
Generally, a weight loss workout begins with a warm-up phase, at least 1-3 minutes. Provided your intensity remains within your target heart rate training zone, (about 120 heart beats per minute – an estimated average for most non health-impaired adults) you’ll spend the next 7-10 minutes reaching your aerobic threshold. Staying near-to, but right below the point where your muscles burn (from a too-highly-intense performance causing lactic acid build-up) will bring you to a virtually perfect “fat-burn.” Yet, THIS very special meeting only occurs at medium-to-low intensities, which takes longer periods of time.
Lipids (a simplified word for “non-water-soluble-fats” within your system) have to move from the outside of a cell, and then proceed to your “furnace” (mitochondria). This is where you break fat down into your “rewarding and much-wanted” by-products – energy (the work you’ve achieved); H2O (sweat); and carbon dioxide (a lot of continuous “exhaling”).
So, if you quit at the 10-minute mark, you deny yourself approximately an additional 10 calories or more per minute of weight lost, primarily from fat stores. Stopping this process at 10 minutes is much like going all the way to the door of your favorite party but never stepping inside…for the “real” action.
