These are things I have noticed about belly fat..after 50s ..that may help u too, whatever your age:
* It becomes exaggerated when u are stressed. The correlation beteeen stress and belly fat has been well established..so we need to de-stress with a firm intent. Funny books or movies. Cooking good food. Art and craft and hobbies. And a regular workout. They elevate your mood and release stress.
* Have a dynamic workout. Interval training..short bursts of exercise followed by relaxing stretches..even for 10 / 20 minutes thrice weekly will have immediate impact. This is a new breakthrough but entire researches and books vouchfor it. So do I.
* Diet is the key. U have to consult a professional if needed but do it so u feel the impact immediately. Trying something that works for your friend may not be the right answer for your body type.
* With yoga ..to lose belly fat ..incorporate dynamic sequences and flows( as shown in video). Dynamic poses are more challenging and burn more fat especially at the belly and thighs.
