Never run then stop then run then stop.
The most effective way to lose weight is
interval training. This means to run for
a good 1-2 minutes, then brisk walk for
1-2 minutes, back to a run, then back to a
brisk walk.
The reason this is most effective is
during your 'walk' period your heart is
still beating, and you are still burning
just as many calories as if you were still
running.. However, you are allowing your
muscles the opportunity to rest, the
lactic acid to be removed, and for fresh
oxygen to be pumped to them to allow you
to sprint again.
The result is, you will be able to train
much much longer allowing you to burn more
calories.
Once you've mastered this you can move
from it to hiit (high intensity interval
training) at which point you would would a
weighted belt, weighted vest, and your
rest period would be shorter.
Be safe,
