Cool Tredmill Regime

 Believe me, it makes your workout go by faster and you will be pleased with the 250+ calories you burn in a half in hour... this is a part of my hour cardio. It's a good workout, especially when you are just getting back into an old workout routine. It's helped me build up endurance, I walk it until I get to 4.6
