I’ve talked about this previously but thought I’d put the information in a FREE Research Byte (interactive infographic) for you.
This is one of the early studies that I did with Bret Contreras that really opened my eyes to how different hip extension exercises target the strengthening of muscle at different lengths.
Of interest was whether the direction of the human body relative to space led to varying accentuated regions of force production in the good morning, 45-degree back extension and the horizontal back extension.
Can you work out which torque-angle curve on the figure belongs to each of the previously mentioned exercises? Check out the research byte for the answers and why you should use multiple exercises for total hip strengthening.
