Here are six 6 Ways to Improve Your Treadmill Workouts:
1. Set the incline to 1.5 to 2 percent
Start by setting the incline on the treadmill to at least 1.5 percent. (Use 2 percent if your treadmill only increases the incline in full percentage points.) This is important because running on a flat treadmill reduces the effort substantially compared to running outside. This little bit of incline helps compensate for the lack of wind resistance and variation in outdoor ground surfaces that make running more challenging and “active” when you’re outside.
