Since I've been drawing more and more, I notice that my lower back aches quite badly
It doesn't hurt while I was drawing, but when I shift, or stand up, it aches.
I don't know if it was the position. I sit on my chair and draw with my tablet on the table, I try to sit straight. But after about 30 minutes my back begins to hurt.
I have been trying to take a 15 minutes rest after every 30 minutes drawing. Been doing back exercise too, don't know if it helps.
I don't know if any one have the same problem? I'd love to know what is your favorite position for drawing? One that feels comfortable for a sketch time. Sometime I have to draw like 5 hours straight.
