In brief: A Few Days

Even after a few days of inactivity you muscles will begin the process of diminishing in strength and size.
Even relatively light workouts can maintain muscle tone, however. Space station astronauts engage in regular exercise and muscle conditioning so that their muscles (including their heart) will be able to function properly upon their return to gravity.
