I have recently started doing walks on the treadmill incline walks to add in some extra caloric expenditure. I know Lonnie Lowery has supported this in the past but I wanted to know how much I am actually working compared to a sprint session. I usually do 2-3 days a week of 2 minute on 2 minute off sprints for sets of 5.
I have been adding in a few days of walks on the treadmill at 7-8 degree incline at 3.5 mph or so for like 45 minutes. I was shocked when the treadmill told me I was burning well over 500 calories in that time when I was only breaking a light sweat. Is there any way that is actually true. How much am I losing out if i am sprinting twice a week and incline walking twice a week vs just doing HIIT 4 times a weeek.
