I actually do this quite often actually, it's really quite stimulating,
So, what you do is, you stretch your arms out straight in front of you, palms facing outwards like you are pushing against something, elbows locked, and look at them. just...just do it. yeah.
And then once you've aptly appreciated the lovely curvature of your hands, spin.
Slowly, quickly, standing, in a spinning chair, to some music, however you want, just keep your eyes trained on your hands and keep spinning.
The resulting sensation will be one of the most exhilarating feelings you will ever experience.
No. Seriously.
Try it now.
It will make your day so much better.
In fact, this exercise (apart from being the closest thing to actual exercise I can get), is sort of on the same level of stimulation/excitement as lying on the ground and pretending you are walking on the ceiling, or looking at the world between your legs because you can, or closing things (laptop, fridge, etc.)to determine exactly when the lights turn off, or lying on the bed with your head dangling of fit.
just.yeah.
ok i'll shut up now.
