All of my weight is in my rear! I do the 3 mile Walk Away the Pounds video w/ weighted balls every a.m. before breakfast (4:45a.m.). Basically you're marching in place at a brisk march, with a combo of side steps, kicks, knee ups , kick backs with added arm movements - the workout is 40 minutes long. Last week I started to get the horrid feet & leg cramps but I started taking cal-mag & potassium & within a day the cramping & tender feet went away.
