What is the best exercise/ fitness gym routine for a nocturnal person like me without developing muscles?
I am working in a call center. I am in a night shift. I also drink slimming coffee and diet pills but none seems to be working. 
. I am planning to enroll in a fitness gym but I think I can only have sessions during my day-offs usually Saturday and Sunday. I also just would like to lose weight and not develop hard muscles. Thanks.
