I am overweight, by 2 and a half stone. I used to weigh 14 stone but I have lost a stone and a half through diet.
I'm just starting to exercise and have joined a gym. Today I did 20 minutes fast walking uphill on treadmill (115 calories) and 20 minutes in the exercise bike (245 calories) but my sister says this is a waste of time and laughed at me!
It isn't right, aibu???
