specially to S'zuan

Here are some tips for you. If still can't work, then i don't know what to do already.

1) jogging - since you so long didn't jog, start with few rounds around the park in front of your house say 3-5 rounds. After like 3 days straight of jogging, then increase to 6-8 rounds. Then when you feel like you can jog for longer distance, try 2 rounds around your housing area. If cannot tahan, then continue with few rounds in the park. *every time you go jogging, after 2 rounds at the park, do minor warm up as in stretch your leg, hand, waist then continue jogging. You won't feel so tired after finish jog (well at least it does work for me).* When you are done, don't immediately stop. Try walk at the park a while till your body cool down(avoid from stroke). You can always bring me go jog if you want but not at taman rakyat(not nice to jog there). We can go botanic or if you rajin, then we can go Stadium Sultan Sulaiman(is that the name? the one we always go for hari sukan) :P
When you go do sports, i'm sure you will feel tired. When you feel that, try to force yourself a little more. All this is for your stamina. Time to jog is 7am-9am and if you can't wake up, go for 530pm-7pm. If hujan then terpaksa la duduk dalam rumah :(

build muscle - you sure you want? cos you are so skeleton. Not suitable. Wait till you gain more weight then you start. For now you do minor minor thing only.

2) Your 'dumbell', carry 10-30 times a day. Do 3 sets. 8-10 times for each set. Don't do more. When you gain more weight, then only your increase the time. *this is for your arm muscle. the front part one. muscular people always will show their muscle. yea that's the part*

3) Do sit-up. This one you want do how many times also can.For start, try 8 times per set. 3 sets. Then slowly increase to 10 times per set. This is for your tummy IF you want la and also your waist strenght.If you feel 10 times per set tak da rasa, then try hugging your 'dumbell' and do. *IMPORTANT. don't force for yourself. If cannot finish the sets, it's ok.Rest for 2-5 minutes during the interval for the sets*

4) Do that hand pumping. The one you need 2 chairs.both leg on one chair and both hands on the another chair. And when you pump, your body is on the air. Only your hand and leg on the chair. When pump, the angle at your hand is 90 degrees(to see angle is at your elbow there). Do 8 times per set. 3 sets. Same as sit-up. This is for your lower arm. Below that hand muscle (sorry i don't know the nam for that body part)

5) If you need your wrist strenght, i'm not sure how to do work on it. As i know is you hold your badminton racket, turn it 360 left and 360 right but the spin is from front to back(or back to front) not clock-wise or anticlock-wise seeing straight in front of your face. If don't understand then when we go play i'll show you.

2) - 5) is for your muscle. 1) is for your stamina. To gain weight, when your semester re-open, stop doing 1). DON'T DO AT ALL!! 2) - 5) you want do can do. Then you see la whether got gain weight or not. If no then don't know what to do already. Maybe faithed to be skeleton :P muahahaha!! Don't go spread this methods cos i don't know whether it's the correct one or not but it definately works for me and quite a number of my friends.

Last but not least, enjoy!!! good luck! Gambate kudasai!
