Just a few of my favorite "simple" stretches--
Always be kind to yourself and check-in with how things feel when moving through the motions.
>SIDE BENDS- Sit tall, extending through the crown of your head. Reach hands overhead, extending through your fingertips. Lean to one side, bending only as far as feels nice for you. Look wherever feels best for your neck. Don't forget to even out! Optional variation- Keep hands on the hips, or resting comfortably.
>SHOULDER CIRCLES- Roll your shoulders forward, up, and back (and reverse it when you'd like to). Feel it out! Maybe you circle both sides at once, or alternate... Maybe smaller circles, or maybe larger ones. Your choice!
>PALM PRESS- Interlace your fingers and press your palms in front. Continue overhead if it feels nice, pressing gently towards the sky. Maintain a tall sit, inviting a neutral spine.
>PALMS BEHIND HEAD- Place interlaced palms on the back of your head, allowing thumbs to rest comfortably on your neck. Invite elbows to open gently. Invite length in the back of your neck. (Is there a proper name for this one?)
>(PALMS BEHIND HEAD continued ^^^)
>WRIST CIRCLES- Find mindful rotations of the wrists, reversing circles when ready to.
>SEATED FORWARD FOLD- I love a gentle fold! Sit tall and invite your knees to be a little bit bent. Reach arms overhead and then forward, allowing yourself to soften towards your legs wherever feels best. You can rest your hands wherever they fall naturally, or wrap hands or arms under the thighs if it's accessible and comfortable. Use your hands to help you press up to a tall sit whenever you're ready to exit the pose. *Don't force the fold! If this hurts your back, please skip it.*
(Do what serves you best and leave the rest! )
