Rounding back? It may be your hips
If you see folks who look like this picture below every time they reach, the causes could be multifactorial. I’ve written about hamstring flexibility before and that can certainly be a contributing factor to losing low back stability on the reach. Another cause that I haven’t written about is hip mobility and that’s what this post will focus on.
Because the low back is anchored to the pelvis and the pelvis connects to the hips, leaning forward on the reach involves flexing the hip and rocking the pelvis anteriorly (think of a ball rolling forward). If all goes well, the low back can stay in a neutral position as if you were sitting bolt upright and simply tipped forward while reaching your arms out. Now, if the hips stop early in flexion (think of stuffing a basketball under your shirt and bending forward), the pelvis stops and the low back must round for you to continue to reach.
Now, while I’m a rehab professional who understands the body very well, I can’t claim to have come up with all the great solutions to helping it along. For that, I look to those who have done the hard work already with good results. Kelly Starrett is one of those PTs. Here are 2 videos of him demonstrating methods to improving hip mobility.
As usual, feel free to leave me your questions and comments below!
