Seven techniques

Raise one hand and point your index finger straight up. Other fingers can be relaxed or curled — keep it simple.

Bring both hands together with index AND middle fingers pointed up on each hand (a 'peace sign' on each, side by side).

Make an 'OK' sign — touch your thumb tip to your index tip to form a circle, with the other fingers extended.

Show one closed fist and one open palm together (left fist + right open palm, or either way around).

Make a single closed fist and face it toward the camera.

Make two closed fists and press them together side-by-side so your knuckles touch (like gripping something between both fists).

Press both palms together in a prayer position. Keep your hands vertical with fingers pointing upward. Make sure palms are fully touching with no gap. Hold steady for activation.

Touch your thumb tip to your middle finger tip. Other fingers can stay relaxed.
