You know how your muscles feel cramped and stiff when you wake up in the morning? After a night's sleep (or another long period of inactivity, like a car trip or plane ride), the parts of your fascia that wrap around and through your muscle fibers, which are normally stretchy and flexible, can stick together like previously chewed Hubba Bubba.
The fix: The best way to release the fascia is to slowly and luxuriously stretch out your arms and legs and roll slowly from side to side before getting out of bed. This will gently pull the muscles apart and separate the connecting tissue, says Wilmarth. To get at the fascia in your calves, ankles and arches, sit on the edge of the bed and flex and point your feet before putting the pressure of your weight on them.
