My legs

My legs feel so tight and stiff...the skin not the muscles...I've been sitting on my butt all day for the past 2 days and I will be until Friday. I'm sitting in on Gifted and Talented training. Currently j am laying on my back in bed with my legs propped up with 3 pillows. What else can I do???? And baby doesn't exactly like me laying on my back right now lol.
