HIIT is all the rage and for good reason in my opinion. It really makes conditioning and cardiovascular work interesting. It is intense and time efficient. I am able to push myself harder knowing my workout is going to be under 20min. It is easy to spot improvements in recovery, power, strength, and endurance when I am working with small consistent time intervals. (Oh my gosh! I did 19 jump squats in 20sec today instead of the usual 17!). Research shows there are plenty of cardiovascular benefits to be had from short intense bursts of exercise. But I have noticed that if I am trying to change my body, all the HIIT in the world doesn’t seem to make my body change like I want it too. My body is stubborn and bizarrely (and annoyingly) what it seems to need in order to change is some steady pace cardio. A respectable amount of steady pace cardio too. With heavy lifting, and a little HIIT on the side. I hate it. I am experimenting trying to find the minimal amount of cardio I can do while still moving forward because I don’t want to live on my spin bike. Ouch.
