Rev Up Your Workout with Interval Training

Interval training involves working at varied intensities in order to challenge your cardiovascular system. Here is a sample for a 30 minute workout. If you are using cardio equipment, the levels will be marked on the machine. If you are walking or running, think of the scale like this:

1 (slow walk) to 5 (moderate jog) to 10 (intense run)

0-5 minutes - 3
5-8 minutes - 7
8-9 minutes - 4
9-12 minutes - 7
12-13 minutes - 4
13-16 minutes - 8
16-17 minutes - 3
17-20 minutes - 8
20-21 minutes - 4
21-24 minutes - 9
24-25 minutes - 4
25-28 minutes - 9
28-30 minutes - 4

Now get out there and work it!
