Acronyms have taken over the world as a way to get to the point quickly, but for those who are attempting to learn something new, they can be quite frustrating when you don’t know a given acronym’s meaning. I came across this with HIIT, HIT, and HIIRT.
HIIT, HIT, and HIIRT are all forms of High Intensity Training, with HIIT being the celebrity of the group. HIIT has lately become the recommended form of exercise over the conventional hour or more workout routine.
If you’re as acronym deficient as I am, here are the needed definitions to get you started:
HIT – High Intensity Training: involves doing one set of each exercise, up to momentary muscle failure or exhaustion. The main principle of HIT is that the workout is short (usually 10-20 minutes) and intense with reps performed slowly and controlled. READ MORE on HIT
HIIT – High Intensity Interval Training: involves short period intervals of high intensity (usually cardio exercise) training done just shy of max effort, followed by a short recovery period of low intensity movement. There is no set number of reps to accomplish, just do as many as you can at high intensity for the allotted time period.
HIIRT – High Intensity Interval Resistance Training: can be considered a hybrid of HIT and HIIT. (Some fitness professionals may just qualify HIIRT as HIIT) It is pretty much HIIT including resistance strength exercises.
What would qualify as high intensity?
On a 1-10 scale of perceived exertion, high intensity can be considered anything over an effort level of 7. When using max heart rate (MHR) as a guide, high intensity can be considered exercising above 80% of MHR.
Benefits of high intensity type training:
– Shorter workout times allows exerciser more free time and causes one to be more motivated to workout.
– Intense, intermittent physical activity results in increased metabolic rate, expedited release of fat stores and increased release of fatty acids to be used as fuel (weight loss), decreased inflammation, improved insulin levels, and reduced cortisol secretion.
NOTE:
Don’t know where to start?
Our X-50 Challenge will guide you through 50 days worth of HIIT, all from the comfort of the device of your choosing! COMING SOON…

You may have noticed that Astone Fitness’ Blog is kind of on a role with giving you all the info you need to know about today’s trends in fitness. We filled you in on Boot Camp Training and Crossfit. High Intensity Training is next in the line up. Though there are a lot of conflicting beliefs, researchers are finding that High Intensity Training is a more efficient way to get workout results than the way we have been doing it for years.
The common way to weight train involves doing a predetermined number of reps in several sets. (Avg. 3 sets X 12-15 reps per exercise) High Intensity Training or H.I.T. refers to a training method that involves doing one set of each exercise up to momentary muscle failure or exhaustion. Exercises are usually only done once a week in order to give that muscle group a sufficient rest period. The main principle of HIT is that the workout is short (usually 10-20 minutes) and intense with reps performed slowly and controlled. This training technique can provide you with a wide range of benefits such as muscle conditioning, fat loss, increased muscle strength and enhanced cardiovascular fitness. Studies are finding that low volume/high intensity training is the most effective way to increase both muscle size and strength.
The idea with HIT is that you put your muscles under extreme stress; creating a huge growth impulse. Then you give the muscles a lot of time to recover and build. There are two main factors in doing a HIT workout properly:
Perfect Execution done Slowly Each exercise must be done with perfect form and done at a natural slow pace. Because this means there is less room for cheating or yanking the weights, the workout is all on the muscle you are working, creating better results.
Going to “Real” Failure In most training methods, repetitions are done to failure. (i.e. you keep pushing until you just can’t move the weights anymore no matter how hard you try, and this is the end of your set) In HIT, you go beyond that point.
Some options that are used to help you go beyond failure are: Human Assistance Your spotter will wait until you reach the point of muscle failure and then support you for another two to three reps.
Pyramid Training Immediately lower the weights after failure is reached and do a few more repetitions with reduced weights. With machines, you can have a spotter who removes a couple of plates for you. With free weights you can prepare a lighter set and quickly and safely switch from your heavy weights to your lighter ones.
Short Breaks Another option is, once you reach the point of failure go back into a neutral position, wait for five seconds and then have another go at completing as many reps as you can.
Static Holds Although you may not be able to lift a weight for another rep you will almost certainly be able to hold it statically for a further period and finally lower the weight at a slow controlled speed. This will take you over the edge to complete exhaustion.
Though High Intensity Training has the perks of achieving greater results in a shorter period of time than the typical multiple set workouts, it should be reserved for those who are already fit and looking for an additional challenge or quick boost. If you are not particularly fit and/or overweight it is recommended to stick with the traditional way of exercising until your muscles are stronger in order to prevent injury.
