1.76 is considered quite a good height liao. Im not sure if
exercising will help in growing taller at your age, but i remeber i
still grow a bit taller when im in sec 3 and 4.
1.8 to 1.83 is kind of just nice(in my opinion).
With this height most girls that you meet should have no problem
putting their head on your shoulders, and they should feel your
安全感.
If you have a big frame better start training now, no need go to
the gym if you have no time, just jog alternate days, do
pushups/situps/pull ups, to make your muscle more define and figure
nicer.
You will be thankful for good looking and healthy body.
As with nice body, u will have better confidence, and Can flirt
with girls more easily during tetiary educaation years.
