So I am up to walking for 30 minutes in the morning and 30 minutes in the evening. I have been walking at 2.5 with little to no incline, but today, I did 3.0 for 5 minutes, then slowed down to 2.5 and raised the incline to 3 for 5 minutes, then raised the incline .5 more for 5 more minutes, then raised the inline .5 more for 5 more minutes, then lowered to 0 and walked at 3.0 for 5 minutes and then finished walking at 2.5 for 5 minutes.
I notice that when walking at 2.5 and 0 incline, it takes almost the full 30 minutes for my heart rate to get up around 140.
When I speed it up... heart rate goes up a little faster, but when I add incline... I can be up to 150-155 in a very short time.
Just wondering what my next step should be... I think I'm ready to up my game a little, but not sure if I should do incline, speed... or both?
