the easiest way to loose weight is jogging... if yo don't have stamina you start with ~20 minutes with small pauses .. then later ~30 with even less pauses then 40 with only 1 pause and then after ~10 weeks 1 hour without a pause.

its the best simply the easiest way.. you stand up early, eat an apple or banana + some juice or so, grab your MP3-player (or something similiar) and start jogging.. the music helps you to run in rhythm and its actually pretty fun because time passes by very fast.

after that you just take a showever and feel great.

if you want to do sports i recommend to play with friends if you were never in a team before. its simply more fun and nobody blames you for doing something wrong ^^
