The content of this book isn't bad. But take this as more of a pamphlet than an in-depth workout guide. Sometimes that's all you need.
The concept is pretty simple and I think reasonable as well. There are 3 exercises that you'll do 10 repetitions of each with minimal breaks basically as often as you can in 30 minutes. Of course, you'll have to build up to 30 minutes. And there are examples of “easier” variants for when you are learning the program along with harder versions for when you need more of a challenge.
Rating: 3.5 stars. I wish there were more photos (with better lighting) and maybe more “variations” options to help with muscle confusion, which helps you get more out of your workouts.
*This is a Kindle Unlimited Title, so if you have KU, you might as well “check it out” it is literally a 20 minute read.
