Small actions, repeated constantly through time, have a much bigger impact than big actions taken only once.
During the night your tissues shrink and stiffen a bit.
Even without knowing all the science behind it, you've probably noticed that, as soon as you wake up, you're somewhat stiffer than later in the day.
If you're interested in the explanation of it, by clicking here you'll be taken to a very interesting video of Gil Hadley, a wonderful human being and incredible Integral Anatomy researcher.
On the other hand, if you just want to enjoy some movement, play the video at the top of this page and jump straight into applied research ;)
These gentle movements are indeed perfect in the morning to wake your body up, but can be a very good intermezzo to long hours of sitting, or when you just want to focus 5 minutes onto yourself.
Enjoy, and let me know how you felt.
