There are many activities that require we stay in place. I'm not sure the best name for these types of activities, but they're tasks that typically occupy our eyes but not the rest of the body. Computer work is one of those "in place" activities, as is reading.
I have historically been an avid reader although I have seen a steady decline of reading time correlating to an increase in my time out in nature which is worth noting. Still, I like to read a little bit each day.
Before becoming a mover, I didn't think much about my form when doing my in-place activities. I wasn't moving so why think about form? Or maybe the form for my non-moving time was simply "keep eyes on page" while I just sort of lounged in or on whatever. I had no specific form for all my non-eye parts.
Now days I'm more aware than ever of my need to stay moving, so my reading form has become pairing the moves I'm trying to get to daily (these will vary based on individual needs) with the reading I like or need to do.
You can also check out some other reading and writing moves here! Ok, the end. All I'm saying is, you can read, or move, or you can read and move at the same time.
