Is walking on the treadmill for 15 minutes in the morning and 15 minutes at night as effective as walking 30 minutes straight?
The answer to this question depends upon your objective. If your goal is weight loss, you’re better off in walking 30 minutes straight. The reasoning being as follows: the percentage of calories you burn from fat will be higher after the 15 minute point, but remember if you can’t do the 30 min straight, then do what you can comfortably handle.
