These are some simple moves that you can do anywhere.  We got these from our friends at healthline.com

Desk angels

1. Sitting straight in your chair with perfect posture, raise your arms straight overhead as though you’re trying to touch the ceiling.
2. Keeping your head and torso stationary, move your arms back and forth. The important part of this stretch is moving your arms behind your head.
3. You should feel some pulling in your midback, which helps to unfold and extend your spine.
4. Repeat 10 times.

Shoulder rolls

1. Keep your back straight and your chin tucked in.
2. Roll your shoulders forward, up, back, and down in a circular motion.
3. Repeat 10 times, then reverse.

Upper trapezius stretch

1. Sitting with your back straight, tilt your head sideways toward your shoulder.
2. For a larger stretch, extend your arm on the same side to provide a gentle pull.
3. Hold for 10 seconds.
4. Repeat twice on each side.

Armpit stretch

This stretch will make it look like you’re trying to smell your own armpit, so perhaps you should perform this one when you’re sure no one is looking.

1. Sit with your back straight.
2. Rotate your head sideways so that your nose is directly above your armpit.
3. Hold your head with your hand and use it to gently push your nose closer to your armpit. Do not push to the point of discomfort.
4. Hold for 10 seconds.
5. Repeat twice on each side.
