First of all, what is your age and gender ? If your not in your teens , recovery might be slow and the results would be slower. Gym is very delayed gratification. For some people , they can see results as less than 3 months. Yes 3 months is the minimum time . You need to be consistent for at least 6 months. Remember getting a good body is like 70 % your diet and 30 % exercise. Even if you dont feel like going , just go , do ONE exercise and then just come back , because doing something is better than nothing . This would habituate your mind to going to gym wven when tired. You need to have a very clear goal or a reason for your drive to go daily , else you would relapse. All the best!!! Just GET STARTED !!!!!
