No-excuses exercises here. Calisthenics needs no special equipment. All you need is a body and we all have one of those. No need to go to the gym. Your body is with you wherever you are. So the only thing you need, besides this book, is to want to move your body. That's not quite as much fun as binge-watching something on Netflix.
So here we have exercises you can do at home, most of them without any equipment whatsoever, not even weights. A good many of the ones included here you are probably already familiar with. The nice thing about the book is the layout, the explanations about muscle anatomy and the illustrations that show you the muscles being worked with each exercise.
There are three levels of exercise programs here. If you've never exercised much before, you should obviously start with Level 1 and, as you get stronger, can power up to the next two levels.
There is a chapter to show you cool-down exercises, restorative poses, and how to develop healthy habits and mindset and one chapter that gives you advice on how to build your own personal workout program just for you and your needs. Also included are blank workout logs to fill in, resources, an exercise library and an index.
All in all, this is a pretty decent exercise book. Will power, unfortunately, is not included. I would have gladly paid a bit more for the book if it had.
