Circuit training is a great way to burn your fat and also helps to strengthen your muscles. But circuit training in itself is not enough for you to achieve great results! You need to also follow a suitable diet for this to work out the way you want it.
Diet does not mean that you have to starve yourself or eat tasteless foods. It simple means to alter your food intake so that both your taste buds and your body is satisfied. Added to this is the necessity of drinking adequate water coupled with proper stress free sleep. If you have achieved all this, the next stage is to start your circuit training.
Circuit training includes push-ups, bent over rows, goblet squats, burpees and the plank. The method of doing each is explained with demonstration in this video. Go through it and get started!
