Is it okay to do an 1 hour and 30 mins of cardio each day?

I do 1:30 mins of cycling each day not becuase i want to but i have to. I think im underweight because i am 5''11 and im 60 kgs. is there any thing you could tell me to increase my weight. I also do 1 hour of weight lifting 4 times a week. I have been doing this for months theres still no difference in my weight.
