Are you a guy or a girl? 5kg dumb bell is too light... I'm 17 and I lift 10kg per hand easily. Plus you do too little sets. You gotta do hell lot more than that to lose weight.

P.s: Not meant as an insult, pointing out only.

Go to Kelab Darul Ehsan. They have a decent gym there. Its sorta near your place.

You from TARC? Cool, I'm from there too. But the gym's so banged up and old. I went there once only.

Lol, I'm doing A levels there now. The old one... only has a few weights. Can't do squats or use the machines. Very cramped too. Yeah, the new gym 4 koko only sigh... But a lot of hot girls thr. Too bad I'm not Diploma student...
