I know that sitting all day is not good for your muscles, but what do you do when you are to tired or sore to get up and to anything? I try and use the 15 minute rule, do something for 15 minutes then rest, but sometimes after I sit down that's it for the day. If you don't use the muscles the harder it is on yourself, but when you try and use them you really seem to pay for it sooner or later.
Any advice would be helpful, Thanks in advance!
