You have to mention what is your fitness goal, what you do in gym, time, so that people who has the same direction can approach you.

The goal to get healthy is relative not quantitative. If you just wan to sweat it out, don't bother going to the gym. Just run and swim because by the end of the day you will quit because you are going to aplace headlessly.

A: Should I turn right or turn left?
T: Where do you wanna go?
A: I don't know
T: Then it doesn't matter if u turn left or right

Set a goal and make yourself accountable.

Do some research on what you wanna do to achieve that goal. Be it weight lift, zumba, power fit (not even sure if there is such a thing), yoga, dances, cardio, etc.

Start with 1 hour. Don't kill yourself on the first day. Stimulate not annhialate.

Good luck in finding partner after you know what you wanna achieve and do.

Proportional? Mind explaining more?

And also, do you mind to elaborate on what are these "much activity entire day"?

Looks like you will need to add some muscle mass while keeping your body fat low. So go to that direction. Don't worry. Lifting will not make you a shehulk.
