Over the past years, Matt's books and Youtube channel have transformed how I manage my personal fitness. The new book is introducing great new strength training methods that require no equipment (or just stuff that I had around, like rings, or stuff in your home, like countertops, doorframes, and other furniture). I've done pushups/squats etc for years, but Overcoming Isometrics has been a game changer for me. A couple weeks in, I am seeing progress that I haven't seen in years. It's a super flexible approach - I'm essentially doing around 20 minutes of OI exercises mixed in with more classic calisthenics, 4-5x per week. That's all it takes! Thank you Matt!
