Instructions
Hold your two palms in front of you at chest height. Your palms should be facing each other.
With both hands, bring your four fingers close to your thumb but not touching. They should be about 1 inch away from your thumb. Your hands should look like they are holding an invisible tube.
Simultaneously, bring your fingers closer to your thumbs as you move both arms slowly directly downward about 1 foot. As your fingers get closer to your thumbs, they should slide under your thumbs. Create tension in your thumbs and forefingers as if you are squeezing something down the invisible tube.
Repeat these actions 2 to 3 times.
