What Is HIIT
HIIT or High Intensity Interval Training is a form of working out where you give 100% effort in short bursts (intervals) with small breaks in between.
HIIT Workouts are getting a lot of hype because they are VERY effective at burning calories, and reportedly continue to do so even after you've worked out due to the EPOC effect (Excess Post-exercise Oxygen Consumption). When you workout your muscles fill with lactic acid (that's the stuff responsible for the burny burny muscle feeling) and your body's oxygen stores become depleted.
After a HIIT workout for approximately 12-16 hours (depending on your body) your body has to continue working to replenish that oxygen and clear out the lactic acid.
Effectively, this means that HIIT workouts achieve the same calorie burn as steady state endurance, in a much shorter time - more value for your workout minutes!
Why Is HIIT Brilliant?
I freaking LOVE including HIIT in my workout schedule for a few reasons:
It compliments my other sports
HIIT has increased my fitness - overtime HIIT will increase your body's ability to use oxygen for energy, so when going back to steady state cardio, I'm stronger and able to perform better.
It doesn't need equipment
Bodyweight is really all you need for a killer HIIT workout. You can of course add equipment, but I'm going to trail this sentence off with Yay Burpees.....
It doesn't need a great deal of time
You can TOTALLY smash out a Tabata (4 minute) HIIT workout, set your heart rate soaring, and basically find yourself gasping for air on the floor (in a sweaty good way)
Or if you're one of the crazier Polkadotsi readers, you can smash out a 30 minute HIIT pyramid. (You know who you are!)
4 minute workouts - I mean come ON 🙂 that's brilliant!
But don't say I didn't warn you.....
