In order to effectively change body composition (loose stored body fat and maintain or even gain muscle) one must exercise for 60-90 minutes five to six days a week. It is very hard to reach this desired goal by performing cardio or strength training alone. Our bodies adapt to what we spend the most time doing. For example, runners generally do not have a lot of bulky muscle because their bodies recognize that muscle is heavy and to run it wants to be light. The body literally tries not to keep a lot of muscle because it would be hard to have when running. Metabolic Meltdown is an interval style class that uses free weights and compound exercises to target your whole body, aiding in the sustaining of lean muscle mass while targeting body fat stores. This class can be sustained for longer periods of time and is the best way to achieve the length of time needed to change body composition while still helping our bodies retain muscle mass.
