I am underweight. How do I gain weight and muscle?
I'm a 20 year old girl and underweight. I'd like to gain more weight so I do not look like a skinny girl. I'm in need of advice how to gain weight as soon as possible. Can you give me suggestions how can I start gaining weight by proper diet, activities like exercises and proper rest?
Note that I've been living a sedentary life for almost 4 years. And experiencing insomnia. Any help is truly appreciated. Thanks.
