fitdude62 saidThis type of cardio is proven to burn extra cals for up to 5 hours after you have finished due to the increase in your metabolism.
Have fun with this.
Not arguing but stating that the EPOC is proven is a little overstating the impact over and above other methods ie various resistance training styles etc
am not underplaying that HIIT is a great method as its highly efficient
but even the top trainers in this field, thinking Cosgrove and Berrardi, agree that whilst studies show great results individuals that try to employ this method on their own seldom do true HIIT style training and even the studies are so varied on the length of time that the High Intensity element should be which again makes for erratic reading.
Any how am nit picking as it still beats normal running styles hands down
