Build strength in your upper arms and discover newfound power and ease in Sun Salutes, arm balances—and everyday life.
The same principle holds for building a different kind of triceps power called isometric strength. In isometric actions, the muscle works but doesn't change length, and the joint it's influencing doesn't change position. You need this kind of strength in many yoga poses that don't involve bending and straightening the elbow against weight resistance, including Downward Dog, Handstand, Sirsasana, and Pincha Mayurasana.
If you're already strong enough to practice the poses we've been discussing, the best ways to build power are through more repetitions and longer hold times. But if you're not strong enough for that yet, you should practice modified versions that come as close as possible to reproducing the action of the full pose.
Work with versions you can happily practice about three times a week. If a strengthening exercise or pose is too hard, frustrating, or painful, you probably won't practice it regularly enough to produce results. Practicing a strengthening move once a week doesn't build much strength.
Take a Chair
If your upper body is relatively weak, you can begin to condition your triceps isometrically by practicing a Downward Dog variation with your hands on the seat of an armless chair. Walk your feet back about three feet from the chair and push your hands into the chair, straightening your elbows, lengthening your spine, and pushing your hips back. (You'll probably feel some calf stretch, but you should be able to keep your heels on the floor.) Then lift your heels and move into Plank Pose, forming a straight line from your heels to your ears. Move back and forth between Downward Dog and Plank a few times. As you practice this over several weeks, aim to gradually build endurance until you can hold each pose for at least a minute.
You can work in this "Plank-on-a-Chair" position to build the strength you need for the Plank-Chaturanga-Upward Dog sequence. Keeping your elbows close to your sides, bend them just a few inches, then straighten them again. These mini yoga push-ups are much easier than the full version but will still prepare you for it.
Hold the Line
When you're strong enough, move to the floor for your Downward Dog to Plank transitions. Again gradually increase your hold times to build your isometric triceps strength. You can also practice mini yoga push-ups, and eventually full ones, from Plank position. In all this work, be sure to keep a straight line through your legs and torso, without sagging in the middle. If you can't hold the line, practice with your knees on the floor and create a straight line from your knees to your ears. When you practice with proper alignment, you target the muscles you want to strengthen. Otherwise, you recruit less anatomically optimal muscles to do the work.
By doing Downward Dogs, Planks, and push-ups a few times each week, you build strength in your triceps that will allow you to practice Sun Salutations and inversions with much greater ease.
While it's easy to use yoga to build triceps strength, building biceps strength is a different story. Biceps are very important in daily life, but they don't get much work in yoga, which doesn't include a lot of lifting or pulling. You may occasionally grasp your feet and bend your arms to pull yourself deeper into forward bends, or work your biceps in Headstand and Pincha Mayurasana. But that doesn't really constitute a strength workout for the biceps the way Sun Salutations do for the triceps.
