Yoga hurts hands?

It depends what kinda postures hurt your hands...you could try yoga blocks depending on which one it is...
Tony Horton (P90X Creator) keeps saying that when something hurts you, don't do it cause you're probably not helping the cause! Not much info but hope this helps

Hi Snazzy. In inverted postures like Down Dog and Handstands etc, place your hands flat on the floormaking sure each finger is equally placed on the floor, spread your fingers equally and draw your fingers in so your finger ends show white as blood is pushed out with the slight presssure.

Now suck the palm of your hand upward as if there is a hot coin under your palm you are trying to avoid. You should feel the static direction is now upward through your arm rather than downward into your hand. This will help you hold the posture without putting too much weight through the heel of your hand.

Also as Plates559 says, focus on raising your hips away from your feet and sinking your heels toward the back of the room (not down to the floor) to bring your weight back a bit and get a nice stretch through your hamstrings.

Hope this helps.
Are you able to get your trainer to check your form? You should expect at least this.

EDIT: Please don't consider wrapping your wrists (unless you have an injury and a professional has advised you to) - this may prevent your wrists from strengthening naturally. Listen to your body obviously.

Thank you! I have the same problem and couldn't figure out why it made my hands hurt to do positions like down dog.

A real pleasure to help - Namaste :flowerforyou:
