U need to practice intelligent eating and put in more cardio and
weight training.
Try to eat more whole grain foods , bread , pasta , brown rice ,
etc . They will keep you full for a longer period of time. Also
break up your meals into 6 small meals .
Avoid fast food and western food at all costs !! Their loaded with
fats ...a good meal will be the chinese standard with rice , vege ,
tofu, meat etc.
Put in more cardio training like jogging , rowing , biking , can
use all the machines at the gym. To get past the glycerol and start
burning fats , get at least 20 minutes of non stop cardio if you
can.
Weight training exercises just need dumbbell and if you can go
gym.
Btw, doing 1,000,000 situps wont give u a six pack if theres a
spare tire around your tummy.
Good luck work hard !!
