Hi,

maybe this is out of scope for this tool, but what do you think about adding
more exercises, e.g. for the knees and legs in general?  This is an important
issue in my point of view for everybody working on a computer.  If you need help
with this, please send me an email.

Bye,
Michael.

The same issue was raise in a Debian bug report, with suggestions as to which excercises would be helpful. Please see http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=371826 for details.

Here are the exercises that Martin F Krafft suggested in his Debian bug report:

  - sit straight up as if your skull was suspended from a string.
    don't forcibly straighten your back though. make sure to sit
    exactly on the bones in your buttcheeks. concentrate on
    breathing.

  - tilt your upper body slightly to either side so that the arm
    dangles loosely. now shake the wrist a couple of times while
    keeping the shoulders loose.

  - stand up, let your arms swing sloppily to either side (left hand
    to right pocket in front of body, right hand to left pocket
    behind body, then vice versa). don't exercise force, just let
    them swing.

  - walk up to the door frame, get upper arm horizontal, point lower
    arm vertically upwards at 90 degrees. hold lower arm to door
    frame, turn upper body away to stretch the chest muscles

  - sit on ground, make soles of feet touch each other. fold hands
    behind neck, elbows between knees, gently pull down the neck and
    entire upper body. breathe normally!

  - standing up, let your arms dangle down both sides and swing them
    back and forth, but only slightly, maybe 20-30 degrees each way.
    concentrate on feeling the weight of your arms.

  - standing up, bend your knees a little, then extrude them; repeat
    in quick succession. feel your upper body shake and try to let
    your arms dangle, let them pick up on the swing.

Another suggestion; received by email from John Florian:

Might I suggest adding a few steps to the finger stretches:

    full finger and thumb extension (fingers straight)
    bend fingers tight at 2nd joint from tip (knuckle, folds fingers in
    half)
    full finger and thumb extension (fingers straight)
    bend fingers tight at 3rd joint from tip (folds fingers onto palm)
    full finger and thumb extension (fingers straight)
    bend fingers and thumb to form a ball (like making a fist)
    full finger and thumb extension (fingers straight)
    fold thumb into palm
    repeat

See also bug 477 with an exercise for the eyes.

I have some more to suggest, from https://www.uhs.umich.edu/computerergonomics#exercise:

Shoulder Rotation: Circle your shoulders, then reverse directions.

Chin Tuck: Slide your chin inward, without bending your neck up or down. This is easiest to practice initially against a wall. Tuck chin in, attempting to touch back of neck to the wall while also maintaining head contact. Don't jam your chin down to your chest.

Shoulder Blade Retraction: Pull your shoulders down and back.

Shrug: Slowly raise your shoulders toward ears and hold for a few seconds. Gradually bring shoulders down and relax.

Arm Rotation: Raise your arms in front of your body. Rotate arms so palms face up, then rotate so backs of hands face each other.

Wrist Flex: With your elbows on desk, gently use left hand to bend right hand back toward forearm. Hold for a few seconds, then relax. Repeat on other side.

Toe Curl: Flex toes up, then curl toes under. Release.

Foot Rotation: Circle foot slowly from the ankle, then reverse.
