In part 1 last week [LINK] I talked about how research is finding the commonly used HIIT model of training is resulting in more negative results on our health. Burn out, injuries, overtraining and poor adherence make it unsustainable.
I introduced a new approach labelled High Intensity Repeat Training.
Let’s jump into Part 2.
Here’s a little fitness map I’ve made that illustrates all the ‘stuff’ we should include regularly.
The main categories include:
- strength training
- movement practice
There is no one item more important than the other, although I am starting to believe that sleep quality and health overrides everything else.
Of this list, the vast bulk of training is the foundation, the aerobic, easy to moderate stuff. Walking, gentle cycling, housework and gardening. The aerobic cardiovascular development is based on having individuals work within their aerobic threshold as apposed to bouncing off their anaerobic zone during HIIT. Aerobic threshold is defined as the intensity just before the beginning of the accumulation of hydrogen in the body, at an intensity where our body can handle the stress put upon it and use oxygen to create more energy and clear away bi-products of the effort.
Can you recall working out so hard you got a ‘stitch’ pain in your side? That’s the build up hydrogen ions from such high effort that the body can’t clear it quick enough. It’s not sustainable.
An ideal aerobic zone is described by Dr Maffetone as 180 – your age. This is otherwise known as the maximum aerobic function heart rate (MAF HR).
Note: You can go to Maffetone’s website for a more detailed way to determine your MAF HR based on your age, health, and activity level.
Now, let’s get to weekly ideals
Health experts recommend 30 minutes of aerobic activity daily or 3 ½ accumulation per week. This is where you should spend the bulk of your exercise effort. This daily 30 minutes can be seen repeated by health bodies around the world. It’s not the maximum, it’s optimal.
Strength is an important function of being an able bodied human, autonomous throughout life to undertake physical tasks and challenges. Who wants to live frail and weak?
When we strength train, our bodies recover and adapt (keeping a long story short) but recover too long and we regress. We failed to adapt. With recovery rates and regressions in mind, an average adult should aim to strength train twice to three times over a week. Think Monday and Thursday or Tuesday, Thursday and Saturday. And yes, you can strength train and perform aerobic activities in one day. You’ll not day. You might get a little tired, but your body will thrive with recovery.
Mobility is the fountain of youth in terms of maintaining healthy movement (yup, even including healthy bowel movements too). We sit, we lie down and we naturally stiffen up a little. To stay on top of mobility, daily practice is prescribed by the worlds leading experts in movement skills. This might mean just 5 to 10 minutes daily of practicing some mobility moves or appropriate stretches.
Sleep. Despite the claims of some people, a body does need 7 to 8 hours sleep at night to promote hormone function for recovery, rejuvenation, organ and muscle recovery and function and brain health.
Nutrition is made out to be confusing. At its simplest, we as humans need daily protein, vegetables, natural sources of carbohydrate, natural fats and water. The exact amounts I’ll not get into here. Where it gets confusing is when people try to fast track their goals, seek out miracle drinks, potions or start to follow extreme guidelines including the removal of complete food groups. If we follow a mostly balanced diet of mostly the ‘stuff’ I mentioned above, most of the time; we’ll be okay.
HIIT. Ah finally. How much is needed if any? Some might not like the following guideline so if I hurt your feelings, suck it up, embrace a fresh outlook and try it to see what happens.
If, and only if, you are able to:
- accumulate 3 ½ hours of aerobic activity in the MAF HR (180-age)
- sleep every day for 7 to 8 hours
- eat a mostly balanced diet
- strength train twice a week
- practice daily mobility / flexibility …
… then and only then can your body be subjected to the stresses of HIIT training that should take no longer than 5 to 10 minutes.
And here’s a serving suggestions for just that.
Option 1: 30 secs of high effort followed by 30 secs rest x 5
Option 2: 10 secs of high effort followed by 50 secs rest x 10
Option 3: 20 secs of high effort followed by 40 secs of rest x 5-10
You’ll notice option 2 has plenty of rest. This protocol is the hidden gem (well, not any more as i’ve just shared it… oops)
Performing at high effort, your goal is to sustain high quality efforts. Answer me this. If you are performing a high effort followed by short rest, how well will you perform the following high efforts? Will there be a drop in forms, in effort? Is that the goal? Is the goal to repeat high effort or just to repeat feeling terrible?
High Intensity REPEAT Training
Now it’s going to get juicy as I take you into the new world of HIRT.
The best athletes do not do HIIT as you see in gyms and bootcamps. Yes, they do perform high effort training, but if you observe their recovery, it is programmed to allow the athlete to perform repetitively, with the goal of finding the sweetest spot of high performance. Injury rate is reduced too with the sustainable high efforts paired with generous rests.
This is nothing new and was in fact around in the 90s but fell out of vogue due to the perceived sexiness of crushing oneself in front of others for the glory, pride and overcoming feeling terrible.
Look, I’ve been on both sides of this paradigm. The first time I certified with StrongFirst (RKC) I was killing myself with kettlebell swings in the older HIIT style. Yes I did get fitter but also tweaked muscles frequently. As I prepare once again for recertification I’ll be following the HIRT style of training that in fact clients followed last January (2018). It was common to see ladies improve their swing from 12 to 20kg to 24 to 32kg in just an 8 week program.
This too was following just 10 minutes a week.
As a guideline, what we followed was this:
- 7 swings with a heavy weight followed by at least 50 secs recovery.
- Pulse levels would increase to approx. 180 – age by the end of each swing set.
- Recovery was based on allowing the pulse to return to 180 – age – 20
- As pulse failed to hit 180 – age, if it wasn’t due to fatigue, the weight was increased.
You could try this with any exercise you are competent in. You must not fear the weight or the tool. Just commit, rest, repeat for 5 to 10 minutes and leave it for another 5 to 7 days.
I don’t know truely know when and where the idea started that we must suffer to develop healthy fitness. Science tells us it’s not a valid method to improve healthy fitness. The media sensationalise high effort and reward.
I personally embrace new findings and new or improved ways to optimise my fitness and strength performance and I’ll gladly say goodbye to crushing myself and risking injury if I really don’t need to.
What do you think?
What’s your action point now?
