Arm supported yoga poses are great for strengthening the arms and shoulders.
Poses include: Lifting up, Cat pose, Knees Lifted Cat pose (Dog Pose?), plank pose, chaturanga dandasana (or crocodile pose or yoga push up), downward dog, dolphin pose, forearm stand, headstand (how to), handstand (L-shaped), arm balances including crow pose, side plank variations including elbow supported and palm supported versions, table top pose, reverse plank, reverse push up, crown supported bridge pose and wheel pose.
Arm supported yoga poses, particularly those where the wrists are bent at ninety degrees or close to it, can be challenging for the wrists and for some people lead to wrist pain. One type of exercise that may help alleviate wrist pain is hanging from a chin up bar. Work at applying tension to all fingers evenly.
When actually doing arm supported yoga poses, focus on using your shoulders to push your hand (or hands) into the floor.
Another possible route to alleviating wrist pain is to use the hands with more awareness. Practice pressing into the heel of the palm, the forehand and the fingertips, then practice combinations of any pair of these pressure points.
Another route to alleviating wrist pain is to tilt the hand left or right with minimal rotation of the forearms.
Tilting the hands outwards may rotate the forearms outwards slightly and create a slight arch in the palm of the hand. This action along with pressing through the heel of the hand and finger tips may be helpful for wrist pain.
Additionally pay attention to the elbows, try stabilizing them, and the shoulders in particular how they are being used with respect to the ribcage.
In general arm supported yoga poses can be built from the ribcage outwards. The idea is to stabilize the ribcage first, making it rigid with intercostal action and/or upper transverse abdominus and posterior serratus anterior activation. From there the scapular stabilizing muscles have a firm foundation, the ribcage, from which to act on the scapulae.
In most arm supported yoga poses, the abs may need to be activated to help support the lower back and so ribcage stabilization can be helpful in this regard also in that it gives the abs a stable foundation from which to act on the pelvis.
With the ribcage, lumbar spine and pelvis stable, then the arm muscles including the latissimus dorsai have a stale foundation from which to operate effectively and efficiently on the arms.
For people with wrist problems, one you've practice some of the hand control options listed above, work at spinal stabilization followed by scapular stabilization in turn followed by activating the hands and fingers.
You could imagine using your arms in a way similiar to pushing a car, you brace your legs, your spine and then use your arms.
Or you brace your spine, then use your legs and arms.
A very simple technique to use for bracing the parts of the spine are to practice lengthening it. As an example, to lengthen your lumbar spine draw your ribs away from your pelvis. Then open your chest and try to feel your thoracic spine lengthening as you do so. Then draw your ears away from your ribcage so that your neck feels long.
Start with keeping the chin tucked in so that you emphasize lengthening the back of your neck.
To practice lifting up with legs crossed, start by spreading your shoulder blades (see scapular awareness), then pull them downwards. Do this with the arms free (elbows can be slightly bent so that your hands don't touch the floor). Practice activating and relaxing a few times. Then put your hands on the floor with elbows straight.
Spread the shoulder blades then pull your shoulders down so that your ribcage lifts up. (Your hands are now on the floor so instead of the shoulders moving down, the same action causes your ribcage to lift.)
Keep your shoulders pressing down and lift your hips. Lower and repeat this sequence of actions a few times.
Then, after pushing down with your hands, lift your hips.
Leave your feet on the floor. Repeat the hip lift a few times, then add the feet.
To lift your feet, try lifting one knee, then the foot, then the other knee and foot.
Depending on how you orient your hands Table Top Yoga Pose can be painful on the elbows. One way around this is to squeeze the elbows.
As with Lifting Up, practice shoulder actions in isolation. For table top that can include retracting and then pressing the shoulders down.

Reverse plank is a more challenging pose using the same arm position.
You can read more about this arm supported yoga pose in the article reverse plank.
In cat pose the exercise can be to protract your shoulder blades so that your ribcage lifts. Then relax your shoulders so that your ribcage sinks down.
As you protract your shoulder blades, focus on feeling your hands pressing strongly into the floor. Notice any change in hand sensation when you relax your shoulders.
For dog pose, the sequence of actions is similiar to cat except you add a knee lift.
After protracting your shoulders, press your feet into the floor to lift your knees.
So that your lower back feels happy, prior to pushing your feet down, try pulling your pubic bone towards your chest. Then press your feet down to lift your knees.
Once you are comfortable in dog pose, try plank pose.
Push your hands into the floor and protract your shoulder blades. Then pull your pubic bone towards your sternum. From there, straighted one knee and push the foot strongly into the floor. (Keep the pubic bone pulling forwards.) Then straighten the other knee and push that foot into the floor also.
A variation of this pose is crocodile or chaturanga dandasana and yoga push ups has details on working towards this pose from the ground up. You can also follow along with this video.
An arm supported yoga pose like downward dog can be learned in stages, starting with the knees on the ground.
Here the focus can start with the hands, pressing palms and fingers tips down and forwards and then from there using the shoulders to push the ribcage back.
Lengthen the spine either starting from the head or the pelvis.
Because your hands are on the floor and your shoulders are, ideally, active you'll find that lengthening your spine causes your pelvis to move backwards.
Once you have a feeling for this try downward dog with knees lifted, then knees straight then with heels down.
Read downward dog for a more detailed explanation of these exercises.
A variation of downward dog that can be used as a prep for headstand and forearm stand is dolphin pose.
In this pose the focus can be on pushing the elbows as well as the palms into the floor. If you do it with hands clasped then press the outer edge of each hand into the floor and as in down dog use your shoulders to push your ribcage back and then lengthen your spine.

Crow pose is one of the simpler arm balances. I've covered it in detail in crow pose.
You can also follow along with this video.
Note how in arm balances the body is balanced on the hands but also one or both legs rests on the back of the arm or arms. These types of arm supported yoga poses can actually be relatively easy. Think of crow pose as roughly equivalent to cat pose but instead of the knees resting on the floor they rest on the backs of the arms.
Side plank is another type of arm supported pose. One way to work towards this pose is with balancing cat.
A more challenging version of this pose, also called bird dog, is to lift the same side leg and arm, and even harder is grabbing the lifted foot with the same side arm.
Side plank and its variations offer a way of practicing single arm strength with the body turned sideways.
Easier versions can start on the elbow and harder versions on the hand. As with regular plank you can lengthen spine, lift chest then work on the hand or start at the hand, then the shoulder then lengthen your spine. For more details read side plank pose and balancing in side plank pose.
One of the more challenging arm supported yoga poses is wheel pose, particularly if your backbends are not that good and even more so if you have weak arms.
One way to work towards this pose is with the exercise I call reverse push up. It's called reverse push up because you do it on your back instead of your front.
Basically press your hands down to lift your ribcage.
The next step up is to move into bridge pose with your head on the floor and repeat the exercise.
You'll then be working on strengthening your arms while moving towardswheel pose.
For more on working towards wheel pose, Working Towards Wheel Pose ebook includes a set of exercises for making wheel pose easier. It's based on the techniques that have worked best in my classes.
