A new study published in the journal Medicine and Science in Sports and Exercise determined that fast,explosive muscle contractions expend more energy and burn more calories than do slow contractions.

Mazzetti's study provided evidence that explosive or more rapid muscle contractions used more energy than slow contractions, even when the amount of weight lifted was identical, increasing the benefits of the exercise for weight loss. It also found that explosive contractions were more effective in increasing energy expenditure when using moderate weight loads instead of heavy loads.

Intensity dictates the efficiency of your metabolism, brain functioning, and especially your hormonal balance.  When applied correctly, high intensity exercise will boost the production of DHEA and testosterone and enhance your workouts, muscle definition, memory, and virtually turn back the hands of time.  

It is important to remember that the intensity of your exercise governs the quality of each exercise session and that these quality workouts are what adds up to produce fast, lasting results.  Intensity makes every rep. count toward your goal. 

Take your workouts to the next level with high intensity training today and never look back!
