Prolonged sitting or standingOur muscles were made to move, recover, and move again. If you spend eight hours seated at your desk each day, or if you run errands that involve standing in line for hours on end, you could be more susceptible to leg cramps than others. A lack of movement is the culprit here, so be conscious of the amount of time you spend sitting or standing.If you stand for a long time with your leg muscles contracted, you may get a leg cramp because you’ve neglected to relax these muscles. To address this, consciously contract and relax your leg muscles and make an effort to sit down and rest each day. Conversely, if you spend your time seated and don’t move your legs enough, poor circulation may cause your legs to cramp; whether you take a short walk or break out into jumping jacks once per hour, try to get up and move every once in a while.

hope this helps
