[Alv123]

After intercourse if I get any najazat impurity on my body then immediately I washed off everything then in the morning before going to gym I don't take bath and wear my gym garments then after coming back from the gym I take bath I know this will clean all the impurity but some day if I don't have intercourse with my husband and before going to gym I use the same unwashed gym garments then tell me this will make me impure najis or I'm pure because I get little sweat while exercise.plz help I'm very doubtful
