Dan John’s Intervention
I am reading multiple books on physical training now. I grab a book or my kindle whenever I find time. I somehow feel that I am short of time and need to quicken things by doing what I like to do the best—reading books. One of my favorite authors when it comes to physicality is Dan John. His book titled Never Let Go is a masterpiece.
On a similar note, I bought a book written by him titled Intervention. However, after reading a few pages I got bored, as it was difficult to get a hang of it. Likewise, if you happen to read his book Never Let Go, because I recommend, you may find yourself lost initially. Intervention is also written in similar lines, so finding the true meaning of what Dan says is obscure, as the writing is objective.
The book tested my patience, for I abandoned reading it—perhaps a year before. Off late, however, I felt again to give it a try, as I read somewhere that this book is a must read for trainers. So, to get the hang of it I read sixty pages of the book without pausing. That helped to understand it better, and then I realized the different layers the book possessed.
Dan John is a very thought provoking writer. I can say that after reading his book you might feel a better and well-informed trainer. He throws away your preconceived notions and opens the door for a better understanding.
Last but not the least, I came across a new piece of information about phasic and tonic muscles which I would like to share. Also, if you are wondering why I included an exercise termed batwings it’s because of Dan’s intervention–Intervention. Tonic muscles tend to shorten and get tight when tired and used less and phasic muscles tend to weaken when you age.
Muscles that get tighter—Tonic Muscles that get weaker–Phasic
Upper trapezius Rhomboids
Pectoralis major Mid back
Pectoralis Minor Gluteus Maximus
Psoas Deep abs
Piriformis External obliques
Muscle—tonic gets tighter, for example, hamstring and pectorals, because of prolonged sitting. Phasic muscles get weaker because of age, so you need to stretch and strengthen them often. However, people in general strengthen only the tonic muscles and neglect the muscles of youth. So train your phasic muscles frequently to save you from the ravages of aging. Don’t only bench press and curl for bicep, but also press overhead, row in different directions, and squat.
