Hello to all,

I'm a 19 year old male and I have trouble gaining weight. My current weight is approximately 52kg and I stand at 178cm.

I eat normally(sometimes even more than what my heavier friends do) but somehow, my weight has been stationary for the past couple of years.
Breakfast :
Glass of milk + nestum
Couple of eggs including the yolk.
A bowl of pork noodle(varies) or other regular coffee shop delicacies.

Lunch :
Rice + meat + vegies + egg.(again, varies) OR fast food like McD.

Teatime :
Chicken ham sandwich. and fruit juice, mainly apple juice home-made.

Dinner :
Rice + meat + vegies + soup.
Fruits afterwards.

Supper :
Burger or instant noodles or mamak or yoghurt bars + milk&nestum
Besides that, I'm currently doing push-ups + squats + dumbbell lifting everyday unless my muscles are sore. (Is it possible to continue the exercises when your muscles are sore?)

Any suggestions or tips are welcomed.

Thanks in advance.
