For many years, the posterior chain was the sole prerogative of powerlifters, who realized that this sequence of muscles was essential to lifting big weights.

With the adoption of powerlifting methods into mainstream strength training, coaches are developing programs that put the posterior chain at the center.

And the results are unmistakable.  With greater hip extension strength, athletes are running faster, jumping higher and increasing in agility.

But while powerlifters made the early inroads into understanding the posterior chain, the researchers have not been slacking.  And in recent years, there have been hundreds of studies investigating the importance of hip extension strength in a wide variety of sporting movements.

These researchers have been busy figuring out how much hip extension strength is needed for different movements and which exercises are most effective for developing it.

And for the first time, the results of these studies have been collected and presented in one place. Hip Extension Torque, covers all the important studies and explains the role of the posterior chain in every movement from walking to sprinting and from jumping to squatting. 

With all this research included, Hip Extension Torque is the ultimate guide to the gluteals and the hamstrings.  It contains all the information you could ever need about the individual muscles, from moment arms to muscle architecture during a huge battery of exercises, ranging from the small, rehab movements to the mainstays of training, such as squat and deadlift variations.

It’s a lot of information: the whole e-book clocks in at nearly 300 pages.  Here’s the chapter listing:

    1. What is hip extension and hip extension range-of-motion?
    2. What is pelvic tilt?
    3. What is muscle architecture?
    4. Which are the hip extensor muscles?
    5. What is the length-tension relationship?
    6. What is the force-velocity relationship?
    7. What is hip extension torque?
    8. How does the degree of hip flexion affect the strength of the hip extensors?
    9. What effect does knee flexion have on hip extension exercises?
    10. What effect does the direction of force have on hip extension exercises
    11. How can we estimate torque for various movements?
    12. What is the hip extension torque during functional activities?
    13. What is the hip extension torque during high velocity activities?
    14. What is the hip extension torque during high force exercises?
    15. How does the proportion of hip extension torque change with increasing load/speed?
    16. What are the directions of future research?

But even though there are hundreds of important studies backing up points for all of these areas, don’t worry about wading through hundreds of study reviews looking for what you need.  We’ve been through and pulled out all of the key facts and figures and presented them in chart form. So you can easily pick out the key points that are relevant to you and to your athletes and clients. 

And what’s more, every study is referenced back to PubMed with hyperlinks, so if you want to go back to the original studies, you can do that with a single click.
