HLM stands for ‘heavy, light, medium’ and surrounds rotating the effort of training each day.
If this sounds familiar that’ll be because around 2010 DUP (daily undulating periodisation) had a minor take off and had people enamoured for a while.
One difference between the two is that DUP rotated between strength, power & hypertrophy days.
HLM will have you stick within a realm that has specific outcome that is the focus.
Alternating the levels of effort allows for a greater amount of progress.
Keep in mind that there are plenty of variables that can be used by the HLM Method.
It doesn’t just have to be reps, sets or loads.
Any of these variables can also utilised:
- Tempo/Cadence
- Velocity
- Movements
- % of RM efforts
- Rest Periods
- Total Workload
There’s basically a lot of options, however it’s totally okay to choose one to two as your bread & butter.
For my own style of programming I will use % of RM Efforts and Total Workload.
Both also effect many other fitness variables, this is where constant progress can be gained.
In the past the HLM style was very popular across full body sessions done 3 days per week.
This allowed for the management of fatigue through volume/intensity.
One common set up was as follows:
Day 1 – Medium Day – SQ/B/RDL – 5×5 for all using 85% of 5RM
Day 2 – Heavy Day – SQ/B/RDL – Ramp to heavy 5rep set, ideally a PB
Day 3 – Light Day – SQ/B/RDL – 5×5 for all using 75% of 5RM
The overall volume is largely the same – 5×5.
What changes is the level of intensity being a % of the total 5RM that was achieved on the H-day.
This allows for a slow accumulation of progression as the aim is to do a little more week to week, be that 1kg or perhaps less.
Auto-regulation is what also helps in the success of the above.
You may find that you only hit the same numbers the week before, it’s okay when that happens.
Spending an extra week using the weights as before will allow you to solidify the progress from a neurological & muscular standpoint.
It’s also not uncommon to find progress in the control of the reps (form), not finding the sets as hard, taking less rest or even being able to pause in the end ROM and drive powerfully out of it with ease.
A set up like this works well for those new to lifting due to the frequency of each lift (3x per week).
Most will get a decent amount of strength as the result too.
When you take a look back through history you’ll find a lot of training programs looked like this.
You’ll also find the worked very well and helped people create a solid foundation for which to build on.
Here’s another example using the same set up from above.
Day 1 – Medium Day – SQ/B/RDL – 50 total reps per movement
Day 2 – Heavy Day – SQ/B/RDL – 25 total reps per movement
Day 3 – Light Day – SQ/B/RDL – 100 total reps per movement
A largely volume based approach that will typically lend itself more towards hypertrophy.
That is provided the average intensity isn’t lower than about 60% of absolute 1RM for each lift.
While is is true that hypertrophy can occur with as little as 30% of 1RM being used it’s worth remembering or rather asking the question of “60%, 30%, whatever % of how much in total?”
This is where strength matters.
If you’re looking for bigger shoulders as an example, and you can only handle say 12kg as a top load for your desired movement then 30% will only be 3.6kg.
3.6kg isn’t really enough to generate a large amount of mechanical tension.
Yes there can be techniques such as BFR (blood flow restriction) for example, that can be sued to make a super light weight super effective however these want to be saved for when you need them.
A lot of people in the modern training world try to rush towards the more nuanced first.
It’s better to focus on the basics and building a solid foundation before looking for sprinkles for the cake.
Here’s a third option using that same set up from above.
Day 1 – Medium Day – SQ/B/RDL – 5-3-2,5-3-2,5-3,2
Day 2 – Heavy Day – SQ/B/RDL – 3-2-1,3-2-1,3-2-1
Day 3 – Light Day – SQ/B/RDL – 7-5-3,7-5-3,7-5-3
You’ll be able to see a combination of the two ideas from above.
Now here is a day for volume, one for intensity and one that is in the middle.
Think about how you can combine this with decreasing rest periods or perhaps time blocks.
Day 1 – Medium Day – SQ/B/RDL – 50 total reps per movement – 15min time limit per movement
Day 2 – Heavy Day – SQ/B/RDL – 25 total reps per movement – 15min time limit per movement
Day 3 – Light Day – SQ/B/RDL – 100 total reps per movement – 15min time limit per movement
The time constraint will make some very different outcomes will be present, the biggest one being a fairly decent level of work capacity (they’ll be fit essentially).
With a constrain is in play the loading will be naturally regulated to compliment the rep goal.
Understanding this allows for interesting and progressive programming can be created.
Since the basic outlines have now been laid we shall look at a tweak in the set up.
Day 1 – H/SQ, M/B, L/DL
Day 2 – H/B, M/DL, L/SQ
Day 3 – H/DL, M/SQ, L/B
H = 5RM ramp to set loads for L/M, M = 5×5 using 85% of 5RM, L = 5×5 using 75% of 5RM
While still a whole body approach the HLM split is now lift specific as opposed to day specific.
You’ll find that upper body movements can be done before lower body ones as they won’t has as much of a neurological draining effect, just FYI.
This style of set up can be very appealing for people that like to lift something heavy each session.
Additionally it’s possible to combine this with time blocks, rep goals and so on.
What’s worth keeping in mind though is that multiple different type of stimulus that drive different outcomes may contradict each other.
As such it can mean that training doesn’t produce a specific outcome.
Playing with the above variables is fun however you can also choose different movements as well.
We will look at potentials for the SQ/B/DL and how HLM works with it.
Squat
Day 1 – H – Front Squat
Day 2 – L – Dead Start Front Squat
Day 3 – M – Pause Front Squat
Bench
Day 1 – H – Close Grip
Day 2 – L – Close Grip Dead Start
Day 3 – M – Close Grip w/Pause
Deadlift
Day 1 – H – From Floor
Day 2 – L – 2 Inch Deficit
Day 3 – M – 1 Inch Deficit
Just like the variation before where you can have a different H/L/M lift each day, you can do this here as well.
Alternatively you can do all the H-movements on the same day, it’ll come down to the goal.
There is also the option of having a rep goal, time blocks and so on.
The next iteration is where you focus the HLM on one lift.
All of the above variable set ups (reps, time, intensity etc) can be applied, for this next option for you we shall be delving into what is a combination of the ‘patient lifter method’ & ‘RM % Efforts’.
We shall say we worked up to a 10RM on a lift, squat = 10x100kg (for the ease of the maths)
Day 1 – H – 6-7 reps per set
Day 2 – L – 2-3 reps per set
Day 3 – M – 4-5 reps per set
Looking at the 10RM, that would be a 100% effort.
6-7reps is 60-70% effort and so on, based off of the RM that is.
In regards to it the actual level of effort that’d need to be measured differently.
Perhaps with the bar/movement velocity for example.
In the organisation of the days you’ll notice all the reps are sub maximal and this is because it allows you to accumulate a decent chunk of volume with the 10RM load.
You can choose to either set a rep goal for each day that is consistent, perhaps 50 reps.
Each time you repeat a session you can add 10% of total volume (5 reps) and accumulate this over time until say you hit 100 total reps.
At this point you’d retest your 10RM.
Over time it’ll typically lead to increases in hypertrophy and strength.
You can do this with multiple lifts, it just means a few more moving parts to your programming.
It’s also possible to use total session time as the variable.
Day 1 – H – 60min
Day 2 – L – 35min
Day 3 – M – 45min
Such a set up would mean on the L days the focus would be on getting what is needed done and then on the longer days M/H there can be more potential for accessory work or the use of heavier loads as longer rest periods can be taken.
This option can be very useful for people that have time as a high priority/value.
It’s also a great option for density and work capacity based training.
You might choose to also prescribe precise rest times to link with the training session or as an entirely separate programming system.
Day 1 – H – 4min rest between every set
Day 2 – L – 1min rest between every set
Day 3 – M – 2min rest between every set
Such a set up can really make people aware of how to maximise training time as during rest periods mobility or restorative/corrective work can be performed.
Example:
A1 Squat x 6-10 reps
Rest 2min and perform – A2* – Upper thoracic bench openers x4-6
You’d simply select an element that didn’t interfere with the main session and lift.
It’s a great way of getting a lot of what is needed done without wasting time, and additionally it appeals to those with the bias that has them feel they always need to be doing something.
Further to the above, you may decide to have a specific rep prescription be used for each set.
Day 1 – H – 4 reps on all lifts
Day 2 – L – 10 reps on all lifts
Day 3 – M – 7 reps on all lifts
There’s also nothing wrong with a 5/10/15 rep set up, the options are literally endless.
Over the course of a training career there will be more total L/M days performed.
While the above uses the example of a 3 day set up it’s more likely that as people progress they will gain more benefit out of keeping training easier rather than harder.
Too many fall into the trap of having too many hard days.
Programming a Light Day after each Hard Day tends to be a good rule of thumb to follow.
Over time you’ll find that out of say 100 training sessions 20 want to be hard and the remaining 80 sessions will be a mixture of light & medium days.
What is key to remember for this style of training is as follows:
Keep light days light for recovery, heavy days heavy for testing a limit and the medium days is where all your progress will be made.
Enjoy,
