According to health experts, there is no necessity to go for such extreme regimen when the work can be done by one simple exercise.
We are talking about planks which is one wholesome workout for the entire body.
Doing planks for about 4 minutes in a day can trim your waistline in less than 30 days.
Here is how to do it-
Start by getting into a push-up position.
Bend your elbows and rest your weight on your forearms. Shoulders, back and ankles should be in proper alignment.
Hold the position for 30 seconds.
Keep your core tight the entire time. Now lie down and relax. You can increase the time with practice.
Remember, the longer you are able to hold the position, stronger will be your core muscles.
