Why and How to Activate Your Muscles in Yoga Poses

For some time now I’ve been suggesting that you add “isometric muscle contraction” to your yoga poses to enhance both strength building and stretching. I, myself, have been experimenting with it quite a bit in my yoga practice, and have noticed some dramatic results. Today I’m going to go into detail about both the benefits of this technique and the best ways to practice it so you, too, can give it a try. 

Why You Should Activate Your Muscles in Your Yoga Practice 

Stretching. When you are stretching a particular muscle, consciously activating the agonist muscle (the opposite muscle to the one you’re stretching) will cause the muscle you are stretching to release (though reciprocal inhibition). For example, if you are stretching your back thigh muscles (hamstrings), activating your front thigh muscles (quadriceps) will release your back thigh muscles, allowing you to increase the hamstring stretch. 

Bone Strengthening. Although a weight-bearing yoga pose on its own will strengthen bones, if you consciously contract the muscles holding you up by firming them toward the bones, you will enhance the bone strengthening effects of the pose. For example, if you’re standing in Tree pose (Vrksasana), firming your leg muscles will enhance bone building in the standing leg. 

Muscle Strengthening. As you work in strength building poses, you can strengthen more than just the obviously active muscles by consciously contracting other muscles as you work in the pose. For example, as you hold you arms out to the sides in Warrior 2 (Virabhadrasana 2), you can activate your triceps as well as your biceps to increase all-around arm strength. 

Joint Safety. For people with joint problems, such as arthritis, consciously firming the muscles that support a joint will help protect the joint from strain or wear and tear. For example, if you have knee arthritis, firming the muscles on all sides of your thighs in Extended Side Angle pose (Utthita Parsvakonasana) will help support your knees. And for people who are overly flexible and can bend easily into deep forward bends and backbends, consciously activating the muscles that are supporting you in the pose will prevent you from hanging from your joints, which can cause injury. For example, instead of passively dropping into pose where you bend backward or forward from the hips, such as Camel pose (Ustrasana) and Standing Forward Bend, (Uttanasana) you can protect your hip joints by activating your upper thigh and lower buttock muscles. 

How to Activate Your Muscles in Yoga

To achieve the benefits I’ve described, you should contract your muscles gently rather than strongly. Strongly contracting a muscle shortens the muscle, which seems to prevent you from moving as freely in the yoga pose. On the other hand, gently firming a muscle toward the bone provides muscular support without interfering with movement. If you’re not used to working this way, it may take some practice. Take it in two steps: 

Joint Safety. For joint safety, you want to emphasize strength and stability rather than promoting more flexibility. So practice as you would for increasing bone or muscle strength by firming the muscles that support your joints. For example, to protect your front knee in Warrior II Pose, you might shorten the distance between your feet so you are not bending your front knee through such a deep range of motion, and then, when your knee is positioned over your ankle joint, focus on firming the muscles on all sides of the knee joint toward the bone.
