Being said about the workout, first find your ideal body type. Anyone who is trying to lose some weight, there is different set of workout. For those who wants to get lean muscles there are different set of workout. I would recommend anyone who wants to lose weight and have great shape, first workout such that you lose the body weight first. If you only have pot belly and want to reduce that, its cardio and food. Also, I would recommend anyone who wants to lose weight and get into better shape, its TIME and TIME. You should not expect the sudden change in 2-3 months. Its going to take some time before you change. If the changes are fast, it means the changes won't last long if you stop doing that.
Make your habit changes. It takes 3 weeks to 4 weeks just to get used to to new habits.
Also, I would recommend not to eat rice for the dinner. Or very less. Like in Nepali saying " Thorai khaye baal, dherai khaye maal".
Porche has good workout routine. Follow that you will see the changes.
But do not expect the changes in 1 to 2 months. I have seen people working out for 2 months and gets frustrated that nothing changed. After every couple of months, you body gets saturated. That means no changes will be seen. So, you need to find different set of workout that works out best for you. Constantly change the workout format. Also, after weights training, donot forget to do cardio for 15 to 45 min. The cardio after weight training reduces lots of fat from your body. If u have pot belly, do not workout your abs. This will get you in bad shape. First try to reduce the body fat then workout your abs. Whole body workout are best.
Also, change the weights for the workout slowly. Do not get too pumped up and lift heavy weights, this will tend to get injury.
For supplements, take scope of proteins any after workout.
This is all for the beginners and intermediate level.
For advanced level, I will post when I get there :)
