How long should a morning walk to be to help impact weightloss?

[jackie21]

Ive started walking every morning first thing when I wake up (put my hair up in bobble, pull my jogging bottoms on and slip into a t-shirt and walk out the door) for around 20mins.

Should I walk longer?
Keep in mind, I have to get on the school bus at around 7.45, and Ill need time to wash and dress and straighten hair.

Excercising regularly can reduce your weight gain and improve your immunity power. A daily 30 minute walk is enough.

If you are a teenager, have a good sleep of 7 to 8 hour. It will prevent the weight gain. Participate in the school games/sports activites too. Swimming and cycling are the other good excercises. Eat well and do regular excercises.

I have always heard that you want to get your heart rate up for atleast 20 minutes. I just take a 30 minute 1 mile walk with the dog in the AM. we will see if it helps.
