There is a zen quality about being upside down. Time expands. The senses you rely on narrow in their input and ones you don't pay attention to become a major source of learning. That's just my perception of what is happening. Biologically, a whole slew of awesome things occur. However, before you can run, you have to learn to crawl and, if you pay attention to the details, these early days (months) will be a vehicle to a newly expanded physical self-awareness.
Much like the lowly ankle joint, no one thinks of their wrists until there is pain. If you are a body weight athlete, then you might remember a time when your wrists were not conditioned for the work you were doing. I teach a style of yoga that keeps you on your hands at least half the time. It never fails, half-way through, and maybe even earlier, new students are dropping to their knees, making a fist with one hand and holding the wrist with the other. They feel pain, but they don't have to.
I never did pre-hab in the early days, I just got some wrist pain and worked through it. Just like a good parent doesn't want his child to make the same mistakes he did, I don't want you to feel that pain. It's not a part of the process and totally avoidable. I was lucky, mine wasn't that bad, I had been doing lots of vinyasa, push-ups, planks, some arm balances for years before I started with the handstand work.
So here are the basics, distilled into a tincture. Bring the awareness into these 3 key components until they become a natural part of your movement work.
- Activate your hands! I can't say this enough. I work with amazing athletes but sometimes I look down and see these limp, inactive hands. You know when you shake someone's hand but it's more like a soft caress...unexpectedly weird. When your hands become a weight bearing base you've got to caffeinate, activate, stimulate and innervate those jello filled latex gloves and get the prana flowing!
- Stretch your wrists! If you lack the wrist mobility, it'll be hard to handstand. Start with the obvious. Stretch your wrists in the direction you need them to bend. But don't forget to take the stretch in the other direction, it'll feel really good.
- Seek to correct imbalances! Often, wrist pain may show up on only one side. It might not even be your weak side. If you have a weaker shoulder, you might inadvertently bear more weight in the stronger shoulder, therefore placing more workload into the wrist of your "stronger side". Pay attention to how you enter and exit your handstand, spend time focusing on your non-dominant side. Bring it up to speed, this might mean you need to work the flexibility of your hamstrings or strength of your shoulder girdle and core. By doing more unilateral movements (i.e. one arm planks, side planks) you will have a better idea of where to focus your efforts.
