1. The Uphill Grind. This is a great treadmill interval, if your just getting started with a fitness program (click here for a great workout to establish your FRF Foundation) you want to decrease the speed and incline to a level that is a little more obtainable.
Start minutes 0-2 with a warm-up at 3.5mph and 3.5% incline
next 30 seconds crank it up to 8.0 mph at 8.0% incline
rest 30 seconds (I stand on the side rails of the treadmill)
repeat 7 more times for a total of 10 minutes
**My goal is to be able to perform this interval with a weighted vest on....eventually.
Give these a try, please leave some comments about how you LOVE or HATE these intervals.
