Here's another way to spice up your cardio training, that will keep you motivated and interested while your sweating it out.
This cardio starts out feeling like it's too easy to be true as it involves a lot of walking but trust me it sneaks up on you. The best part however is it will burn 500 calories!! Almost half of what your calorie intake should be for the day.
Here it is:
Incline/Gradient Speed Time
5% 6.2 - 6.5 5 mins
2% 9 3 mins
2% 11 1 min
10% 5 - 5.5 1 min
Repeat 4 times to make up a 40 minute cardio training session.
Now go get your running shoes on!!
