點樣可以減腰唔減胸? (20點)

要每日扭呼拉圈, 鈕20分鐘倒, 咁你就只會瘦腰唔瘦胸.

Wow!! I clicked on your question as I was thinking you will get lots of great ideas from everyone. However, the answer seems to be just the one about the same website.
I would sugguest you to do sit-ups, just go back to the basic and it works for me. However, sit-up has to be down on a regular basic, if you do 100 today and leave it until next month, you won't see the result.
I do 200 everyday after my 30 minutes run at lunch time. I try not to have a heavy lunch too. It will be impossible to lose a belly if you sit for hours straight after your big meal.
Try to exercise in the morning as it will help you to increase the energy level and do it everyday if you can as a routine. Good luck!!
