السلام عليكم ورحمة الله وبركاته أحسن الله إليكم I love going to the gym. I train 1hour40min 5times a week. Is this considered excessive and a waste of time ? فتح الله عليكم

You decide this may Allah reward you, specially if you have time and you are carrying out your duties and obligations. If it clashes with them then maybe u make 3 or 4 times a week 1 hour only so that you can carry out your duties and obligations.
