We all want to be lean, fit and healthy, right? But how can you choose the workout plan that will yield the best results in the least amount of time? The hardest part of exercise may not even be the workout--it may be finding the time to stick with your new routine.

The great news is that pull-ups are an incredibly efficient way to work your entire upper body and core in less than 20 minutes a day, 3 days a week—with no special training or fancy equipment! You can strengthen and sculpt your arms, shoulders, back and abs by following a progressive training program using pull-ups. 7 Weeks to 50 Pull-Ups features that routine—and much more. The routines contained in this book will detail the plentiful benefits of pull-ups, such as vastly improved muscular endurance in your upper body, arms and core, more lean muscle, and a metabolism fired up to burn any excess fat.

I’ll say it again: 20 minutes a day, 3 days a week. It’s important that a workout be easy to follow, quick, and show results almost immediately. If an exercise is too difficult to follow or remember off the top of your head, you just won’t stick to it. And if you don’t see results quickly, you’re likely to give it up—like all those other fitness goals and plans that you probably didn’t finish. So, believe me when I tell you that if you follow this program, you’ll feel the results immediately and be well on your way to a leaner, fitter, healthier you.
