I have a little secret to share. Over the past six months, my colleague Chris Beardsley and I have been working on a huge project.
I can’t begin to estimate the number of hours that have been put into this project. I suppose it started 22 months ago when I arrived in New Zealand and began my extensive researching expedition. I didn’t have many friends out there, so I’d just stay in my office, downloading and categorizing one article after another. Some nights I wouldn’t go to sleep; I’d work overnight and my professor would arrive in the morning and chew me out for neglecting my health. But I wasn’t concerned – I was building the world’s greatest scientific library on the posterior chain.
Over the past 22 months, I amassed around 1,000 articles pertaining to glutes, hamstrings, and hip extension. It’s quite literally too much for any one person to handle. This is where Chris Beardsley comes in. I approached him six months ago and asked for his help. I sent him all the studies and left him alone for a while to assess the situation. What I did not realize at the time was that he is likely the most competent individual in the scientific fitness community. I remember my first phone call we shared on the subject – I gave him some instructions and guidelines, and somehow he ended up far exceeding my wildest expectations. Without Chris, this product would not have been possible. No way in hell. I’m just not that competent. Chris was able to create in real-life what I had envisioned in my mind but could not have completed by myself.
By combining our talents, Chris and I have pulled off what I believe to be the greatest scientific fitness product ever created. It’s centered on hip extension and the posterior chain, but it covers a huge array of topics.
It also covers research that I have yet to release to the public – things I’ve learned from collaborating with a top engineer across the world, from having discussions with top researchers, and from conducting various experiments. So there’s a lot of information in this eBook that cannot be found anywhere else in the world.
If you are interested in glutes, hamstrings, hip extension torque, torque curves, power, strength, force, hypertrophy, biomechanics, moment arms, muscle physiology, powerlifting, weightlifting, bodybuilding, squats, deadlifts, good mornings, kettlebell swings, hip thrusts, back extensions, sprinting, jumping, sled work, glute ham raises, etc., then you will absolutely love this eBook.
I’m not sure how many studies we referenced, but there are probably more than 200, and almost each page contains graphs, charts, figures, and links.
I wish there was a product out there like this fifteen years ago – if so it would have dramatically accelerated my knowledge and understanding of sports science.
Chris and I combined the practical knowledge we’ve learned as lifters and trainers with the scientific knowledge we’ve learned as sports scientists and biomechanists, and the result is something that I’m so proud of it’s hard to describe.
This is a product that you’ll want to read over and over again, sort of like a modern day Supertraining (Mel Siff).
My readers know that I’m a very honest man. I can guarantee that you will be incredibly impressed by this product. It’s unlike anything else I’ve ever seen (and I’ve seen it all).
The time Chris devoted toward creating the product, the hours I spent obtaining the literature, the hours Chris devoted to obtaining his own literature, the energy that went into planning, editing, and improvements, and the branding of the product – it all shines through.
If you are a serious lifter or athlete, a trainer or coach, a therapist or clinician, a sports science researcher or a professor, a fitness writer or blogger, then this is the product for you. If you study this diligently, you will be more knowledgeable about biomechanics than 99% of the fitness world.
While Strong Curves (comes out in April 2013) is a programming book that contains workouts and exercise descriptions, Hip Extension Torque is a scientific book that gives you biomechanical explanations and creative ways to enhance your understanding of the posterior chain.
In this eBook, Chris and I teach you all sorts of biomechanics topics. We teach you what torque is and what influences torque production. We teach you how to calculate the hip extension torque your posterior chain muscles create when you perform squats, deadlifts, good mornings, back extensions, and 45 degree hypers. We summarize all the available literature conducted on hip extension torque pertaining to functional, high-velocity, and high-force exercises. We even have portions devoted to pelvic tilt, the elderly, and basic hip extension activities such as gait and sit-to-stands for the physical therapists out there.
Basically, this eBook is almost 300 pages of pure awesomeness. It has my full stamp of approval! I will be referring to this product quite often over the next couple of years.
You can buy this product by clicking HERE. I’ve seen fitness experts sell things for hundreds of dollars that don’t contain a fraction of the content found in this eBook, and right now we’re offering it for only $49. The first 100 purchasers will receive a free one-hour group-conference call with me. Just throwin’ that out there.
