Here 5 exercises I normally practice that help me a lot for my mobility, give them a try.
The idea is to gentle roll forward on your back, try to ease the strain on your head by landing on the top of your back.
Here is the opposite, try rolling back clearing your neck by using your hands.
SIDEWAY SUPINE/PRONE ROLLING
Lay down on a supine position lift your hands and your feet and roll sideways, make sure you don’t touch the floor with either limb.
SINGLE LEG REVERSE STAND
Similar to the backward roll but here, try taking off by crossing one leg behind, after doing that use the momentum to roll, use your hands to ease the pressure on the neck then take one leg out so you can roll into a full stand.
Last but not least, here is a little more difficult, here use the momentum sideways, by rolling over your shoulders keep your hips tilted towards your head, this way you wont lose the movement and land on your back, after clearing the roll place the first knee on the ground until your second knee follows.
Do not attempt if you suffer from any spinal injury.
