Healthy Asana Practice: Don’t Stretch Your Joints!

Some Ligaments of the Hip Joint

Healthy Asana Practice:  Don’t Stretch Your Joints!

Last spring I was honored to be invited to co-teach a training at Avenues Yoga Studio in Salt Lake City. The 20-some students were earnest, curious and right on board with our slower-than-usual approach to asana practice, and our emphasis on meditation and philosophy. I am inspired to know that this group of teachers is bringing their wisdom into the world of yoga.

Early in the training, one student who had been teaching in a fitness studio asked a very important question. She explained that one of her female students became unusually flexible prior to ovulation, probably because of the presence of “relaxin,” a hormone that relaxes the ligaments that hold together the various joints in the pelvis—hip joints, sacroiliac joints and pubic symphisis. The teacher said that she encouraged the student to move farther into poses at that period in her cycle since she was already more flexible. “Should I continue doing this?” she asked.

Twenty years ago I would have said yes. In fact, I did encourage women to take advantage of their relaxin-induced flexibility during pregnancy. No more.

Fortunately, the third(!) time I took anatomy, the importance of understanding the structures of ligaments and tendons finally sank in. (For clarification, ligaments connect bone to bone in our joints; tendons connect muscle to bone at the joints.) Ligaments and tendons are constructed of dense, regular, collagenous, connective tissue. Ligaments are dense, fibrous tissues that are designed to limit the movement of our joints. Please repeat this three times:  Ligaments are designed to limit the movement of our joints.

This is also very important:  Ligaments and tendons are considered to be avascular, i.e. containing no blood flow of their own. Oxygen and other nutrients diffuse into ligaments and tendons from cells outside the tissues. Because these structures need to be strong, they are largely comprised of collagen fibers with some elastin to create a small amount of stretch.

Don’t Sprain Your Body!

Ligamentous Tissue

Have you ever sprained an ankle? How long did it take to heal, and did it ever return to its former stability? When you sprain your ankle, you overstretch ligaments. Because the tissue is avascular, it does not heal as quickly as muscle does. Ligaments do not have the “memory” that muscle tissue has. When you overstretch ligaments, there’s a good chance they will not bounce back to their former length. If ligaments are meant to protect joints by limiting their movement, continually overstretching joints can lead to joint instability over time. I know a number of serious practitioners who are now in their 50s—including myself—who regret having overstretched our joints back in the day. All too many longtime practitioners now own artificial joints to replace the ones they overused. Those fancy poses way back when were not worth their consequences.

Flexible people have a much stronger tendency to overstretch joints than stiffer people do. Armed with the pervasive “no pain, no gain” philosophy, we flexies tend to keep stretching until we feel pain. Because our muscles are loose enough that we don’t feel much there, we collapse into our joints where there’s plenty of sensation. Not only does this overstretch our ligaments, it can also wear down the cartilage that protects our joints and keeps them articulating smoothly.

The Counterintuitive Answer

My advice to the student’s question was to encourage her student to protect her joints, to do less rather than more. Counterintuitive, I know, especially when many asana classes encourage people to push past their limits and rock those fancy poses. If a person’s ligaments are made unstable by relaxin—or by excessive heat or any other outside factor—that creates a situation of imbalance in the joints. You wouldn’t encourage a muscle-bound yoga student to lift more weights and stiffen up. Equally, a too-flexible student doesn’t benefit from becoming even more flexible. Too much flexibility is just as unhealthy is too much stiffness. Balance is what we’re going for in asana practice. Familiarize yourself with what normal range of motion looks like.

By all means, do practice to lengthen your muscles, and remember that it takes 30 seconds of continuous stretching for your muscle spindle neuron to actually allow your muscle to habituate to a new, longer length. So take your time, and be gentle. When you feel tissue stretching along the bones—as long as that stretch is not extreme—it’s probably healthy. When you feel discomfort in a joint, please stop doing what you’re doing. And please protect your students’ future joints by teaching them the difference.

    Charlotte i totally agree, yoga of today has gone wild, feeding into the adrenaline junky in all of us….
    this is why i appreciate iyengar yoga more and more….its not about quantity but quality mindfulness…if we slow down take time in pose we can realize that we are over or under doing and we can learn how to do it correctly…
    i believe the propensity of hip replacement in the yoga community is due to over stretching or wrong practice.
    if asana done correctly, rt. actions we can maintain a healthy body and mind….but you already know that..

    Thanks for your comment, Rogelio. I do understand that the sped-up yoga that’s popular now is a good way to get exercise, but that’s not why I personally practice asana. If I want exercise, I’ll take a brisk walk. For me, asana is about the balance of energy and calm that makes my whole life more sane. At 50-something, I’m feeling the effects of the crazy poses I did 20 years ago, which tells me that as a teacher, I have a responsibility to lead my own students down a different path. As you say, the slowed-down, careful approach of Iyengar yoga helps people stay aware of how they are practicing–what works and what doesn’t. I intend to be practicing when I’m in my 90s if I make it that long! But I’m well aware that my practice will likely look different from what it does now.

    I totally agree that in the hot power classes without proper alignment, people are getting hurt and pushed into overdoing it …but, some may be confusing this misguided yoga of overdoing it with the healthy stretch the joints, ligaments and fascia get in Yin postures with long holds. There is a healthy way and a dangerous way to stimulate and strengthen the joints.
