The Train (Interval Run - Intermediate)

This run always makes me think of the movement of a train (not to mention the "chugga chugga choo choo!"), but you don't have to be silly like me; just stick with it and you're be on the way to destination slim!

Muscles worked: All (cardio)
Time to complete: 20 minutes
You will need: Treadmill

• Minutes 0-3 (3 min): Warm Up by walking at a moderate pace (3.5-4.0 speed)
• Minutes 3-6 (3 min): Jog at your moderate pace (70% of MHR*)
• Minutes 6-9 (3 min): Run at a fast pace (80% of MHR*- about 7-7.5 treadmill speed
• Minutes 9-11 (2 min): Jog at your moderate pace (70% of MHR*)
• Minutes 11-13 (2 min): Run at a faster pace (85-90% of MHR* - about 7.5-8.5 treadmill speed)
