To summarize, the described training is enjoyable, fun & minimalistic, and the Power Swings engage the glutes, grip strength & Zone 1, 2 heart rates, which is unique & valuable. It is simple, feels effective.
10 seconds on, 50 seconds off, upto 30 sets. Day after, a big press. Read the book, there's more nuance to it ... .
Actually, this is great programming when busy for work.
All praise aside for this workout & its benefits, a healthy lifestyle & workout programming is much more than only kettlebell swings. It is walk, water, sleep, ... . It's being active outside ... . It's rolling, crawling, thrusting, lifting, walking, rucking, running, sprinting, hanging, playing, going all out sometimes ... . It's eating healthy stuff & not too much. Everybody needs to move, a lot, all-round. To give credit, Pavel hints to this in the book e.g. reference to rucking.
It's also a short book. S&S, Q&D & Axe could all naturally fit in one book ... .
A usefull critique Youtube video is from Lebe Stark, who sums up this sentiment.
Finally, it comes across as not written for the general population. This feels like it is written for the S&C professional ... .
As a conclusion, I liked it, interesting & valuable read. This book might help to make your lifestyle & workouts more complete. And anti glyco training is really usefull!
PS. Trigger for reading this book was "Intervention" from Dan John, who praises the KB Swing as a game changer: "The KB Swing is a fat burning, athlete builder ... . Yes, it is that good."
Like Pavel says, it is not a Swing, it is a "throw & catch".
IMO, Dan John & Pavel complement each other perfectly!
