All the ladies who want to lose weight from tummy,hips and arms...

hmmmm its nice you are keeping your self active. How is your fitness level?
lets do it. stop your aerobic class for a week or so.
And jog in the track(1.4kms). Start where you feel comfortable and do it for a week.
Towards end of the week push your self and time it.
And let me know how many lap you were able to do and how long it took.
Make sure after each running session you use those abs machine at home. Going up/down stairs few time will help building stamina too.
