Handstand can seem daunting but there are steps you can take to build up wrist strength and confidence.
Start in Down Dog near a wall and walk your way up to form a right angle with your body. Keep the fingers spread and the backs of the knuckles pressing into the earth. Keep your neck in line with the rest of your spine. Then over time you can walk your legs further up the wall! Eventually you will have enough core strength to balance freestyle like Jack!
