Yoga and Truth About Twists
When we think about twisting through the low back, we often think about the muscles we could be strengthening or stretching through the movement. However, we do not often consider the risks of twisting as for those of us with healthy backs; it does not seem that precarious a movement. For those of us in careers that require repetitive twisting, the dangers of twisting may be apparent to you. Twisting has been proven a factor in the incidence of occupational low back pain.
If this motion has been recognized as a threat for employees in some jobs, how does that relate to a yoga practice? Are all types of twisting bad?
There is no need to panic, but there is a need to learn and become aware of the postures that are potentially perilous and how to remain safe in them. Researchers first thought that twisting could actually cause tears in the intervertebral disc. However, since, the research community has found that the disc is not actually the structure under the most stress at the end range of twisting, but instead the facet joints are. Facet joints are those on the back side of the vertebrae. They limit rotation in varying amounts throughout the entire spine. For example, more rotation is possible in the low back and the neck, than in the middle back. Therefore, the facet joints can take a real beating with excessive, end range, twisting causing joint irritation.
The strain on vertebral ligaments through twisting is minimal; however, the posterior (back side) ligaments can be strained if the joint was in full flexion before the twisting motion. This could be due to the fact that the ligament is stretched and is then more likely to allow excessive rotation, causing injury. However, if you are performing your forward flexion poses properly, you should be alright. “Properly” means that you are maintaining your low back curve; the flexion should take place through your hip joints and not your lower back.
The problem with twisting is that there is no one muscle that is made to move the body through the movement, unlike our low back extensors which have the primary function of extending the low back. Therefore, to accomplish twisting poses, all muscles need to co-contract which dramatically increases the compressive load on the spine. To give you an example of how movements in the lower back compare in respect to their compressive loads, check out these numbers. If you supported 11 pounds 1 meter away from your body (50 Nm of torque) while in low back extension, 180 pounds of force would act as compression on the spine. The same amount of torque supported in a side bend enforces 315 pounds of force, and while twisting, believe it or not, that 50 Nm of torque places an enormous 674 pounds of force through the spine!
Let us apply this to yoga. This research was done with occupational hazards as the focus and therefore twisting was performed while holding a weight of some sort. Although in traditional forms of yoga, weights are not used, our arm can be considered a weight when gravity is acting on it.
Another major concern with twisting is that it should not be combined unsafely with low back flexion as that movement combination creates the greatest risk for disc herniation. Therefore, when you flex forward, always ensure that you maintain your lower back curve, especially if you are also twisting.
This information was not intended to tell you that yoga twists are dangerous, but that you should be aware while in them and to know how to do them safely. Do not meet your end range and be sure to maintain your lumbar curve. If you participate in a form of yoga that uses weights, avoid twisting with the weights. If you go to the gym, twists on the pulley machines are also not recommended, again due to the compressive forces acting on the spine. If you are an individual who is lifting heavy objects often, including babies, boxes, heavy pots, or even gardening materials, keep the objects as close to your body as possible to reduce the load on the spine.
Think about a door and hinge. If you want to slam the door shut; is it easier to accomplish this by pushing the door closer to the hinge or closer to the doorknob? It is easier closer to the doorknob as the distance from the hinge to the doorknob is greater (this distance is the lever arm). The longer the lever arm, the less force required to achieve a certain amount of torque. To simplify: the farther the distance the box you are carrying is away from you , the less weight is required to adversely affect the spine. So, keep things closer to your body while twisting, whether light or heavy, and your spine will take less of a beating.
Take home points:
- Don’t twist to end range
- Maintain your lumbar curve
- Avoid flexion with rotation in your daily life, but while in yoga, be mindful of your curve and your end range
- If you are lifting objects while twisting, keep them as close to your body as possible to decrease the load on your spine
- Keep learning about your body and stay healthy!

5 Yoga Poses to Improve Your Sex Life
If you are wondering what the connection is between yoga and sex you are not alone. Many people automatically think that there can’t be a connection there. But, it is important to know that yoga can help you have better sex. In fact, many people including fitness instructors, and medical professionals recommend yoga for improved intimacy.
What is important to remember is that being fit in general is likely to give you more self-confidence. When your self-confidence levels are high, your satisfaction in the bedroom will automatically increase. It will still actually increase even if the sex doesn’t change at all! How amazing is that? Practicing yoga and exercising in general can also provide a better awareness of your body. This is important to having a good sex life. You may notice things about your body when you practice yoga, or just stretch. You can begin to better understand your body, its flexibility, and your limits. This alone can help to improve your sex life.
The art of yoga relies on body awareness, body movement, and breathing. Many experts say that these three components are important to having healthy intimacy levels. In fact, did you know that by practicing yoga, your sex life will improve even if it wasn’t your goal or the main purpose for you taking up yoga?
As previously stated, when you have better body awareness, you are more likely to enjoy sex. Body awareness is one of the many foundations that yoga is built on. Being aware of your body can help to give you a better image of yourself, which can, in turn, increase your sex drive and ignite passion.
As for the breathing in yoga, it is so much more than just taking a breath while sitting on the couch at home. The breathing that yoga calls for actually helps to make your spine and your pelvis stronger. What does this mean for intimacy? It can result in better action and movement. You may find yourself being able to have sex longer. Your ability to try new sex positions also improves.
If your significant other isn’t currently practicing yoga, encourage them to try it! Practicing yoga together can also be quite rewarding.
