One of the most common excuses for not going to the gym is that there just isn't enough time to fit in a workout. Now, a busy life needn't be a barrier to exercising! In this easy-to-follow book, fitness trainer Zen Martinoli shows you how you can get a great workout in a fraction of the time you would spend at the gym. What’s more, the workouts in this book can be performed anywhere and at any time. From beginners’ exercises to advanced-level training, it proves that short, intense workouts are just as—if not more—effective than a long gym session. Brief, intense periods of activity will metabolize fat, increase levels of fitness, and reduce stress levels. And with shorter workouts, the return on your investment is so much greater!
