Hello everyone, to be honest i don't do any kind of workout & yes that is really bad. Belly is getting bigger, weight going up, double chin is also getting bigger & etc.

I would like to take the first step to begin working out & hope that all the experts here can give some pointers. I would like to start it out at home, I dont have any exercise machine, so what should i do? 

I hope to accomplish the following:

1. Reduce weight
2. Reduce waist line, reduce the fat belly & man-boobs
3. Reduce buttock size
4. Remove double chin
5. Built stamina

What kind of exercise should I start? How long per day?

Thank you everyone.
