Drop sets, myo reps and every other set type, explained.
Herculex logs 19 kinds of set. Here is what each one is, how to do it, when it is worth using and how the app counts it towards your volume and recovery.
Basic & warm-up
The sets every session is built from.
—
Standard set
A normal working set through the full range of motion.
A set with a fixed weight and rep target, performed with controlled tempo and full range of motion. It is the foundation of your training volume.
How to do it
Pick a weight you can lift for the target reps with good form.
Lower under control, drive up, and stop the set at your planned effort (RPE).
Rest, then repeat for the planned number of sets.
When to use it
Always. Most of your sets, and every heavy main lift, should be standard sets.
In Herculex
Weight and reps count in full towards working volume and tonnage.

W
Warm-up set
A light set that prepares your joints and nervous system.
A lighter set performed before your working sets to raise temperature, rehearse the movement and groove the pattern, without causing fatigue.
How to do it
Start with an empty bar or a light weight for 8–10 reps.
Add weight in steps while dropping the reps (for example 50% × 5, 70% × 3, 85% × 1).
Stop well short of fatigue, then move on to your first working set.
When to use it
Before the first heavy exercise for a muscle group. Later exercises for the same muscle need fewer warm-ups.
In Herculex
Marked with a flame or a “W” badge and excluded from working volume and tonnage, so it never skews your heavy-set stats.

Hypertrophy & intensity
Techniques that extend a set past the point where it would normally stop.
D
Drop set
Hit failure, cut the weight, keep going.
You take a set to (or very near) failure, immediately reduce the weight by 10–30% and keep lifting to the next failure, with no rest in between. Usually one to three “drops” in a row.
How to do it
Lift your normal working weight until you cannot complete another clean rep.
Reduce the weight straight away, by about 20%, with no rest beyond the time it takes to change the load.
Lift to failure again. Repeat once or twice more if you planned several drops.
When to use it
On the last set of an isolation exercise or machine movement, where changing the weight takes seconds: cable work, leg extensions, lateral raises, curls, pec deck.
Watch out. Very fatiguing for the time it takes. Keep it for the final set of an exercise; one drop set per muscle per session is plenty to start with. Avoid it on heavy barbell compounds, where a fast weight change is awkward and technique breaks down.
In Herculex
Pick the drop percentage (10, 20 or 30%) when you choose the set type. Herculex rounds each drop to a weight your equipment can actually load. Every rep you log counts, at the weight you actually lifted.

DN
Down sets
Same weight, one rep fewer each set.
A chain of sets at one constant weight where each set has one rep fewer than the one before (10 → 9 → 8 → 7 …). They are labelled D1, D2, D3 …
How to do it
Choose a weight and a starting rep number you can reach on the first set.
Rest your usual time, then do the next set with one rep fewer at the same weight.
Continue until you reach the reps you planned to stop at.
When to use it
To accumulate quality volume at a heavy weight without grinding every set to failure. Works well for strength-focused accessory work.
In Herculex
Long-press the Down Set badge and Herculex fills the whole chain for you. Each set is counted as full working volume.

RP
Rest-pause
Go to failure, breathe for 15–20 seconds, squeeze out more reps.
A main set taken to or near failure, followed by a very short rest (15–20 seconds) and a few more reps, often repeated two or three times. The brief pause lets you recover just enough to keep the muscle working under load.
How to do it
Do a set to or near failure.
Rest 15–20 seconds, racking the weight if you need to.
Lift the same weight again for as many reps as you can (typically 2–4).
Repeat the pause once or twice more.
When to use it
To get a lot of hard reps into a short time on a machine or dumbbell movement, when you are short on time or one all-out set is all you plan.
Watch out. It is demanding on the nervous system. Do not stack it across every exercise in a session.
In Herculex
Records the total reps and the pause length. Counted as 1.0× tonnage, with 1.2× CNS load in the recovery model.

PA
Pause reps
Hold the hardest position for 2–5 seconds on every rep.
Each rep includes a deliberate stop, usually in the stretched or bottom position, for two to five seconds. It removes the bounce out of the bottom, so the muscle has to produce the force on its own.
How to do it
Lower under control to the hardest point of the movement, such as the chest on a bench press.
Hold still for the planned 2, 3 or 5 seconds, staying tight.
Drive up without bouncing and repeat for every rep.
When to use it
To build strength out of the bottom position, clean up technique, or get more from lighter weights.
Watch out. Use lighter loads than for touch-and-go reps. Pausing makes the same weight feel much heavier.
In Herculex
Pick 2, 3 or 5 seconds when you choose the set type. Counted as 1.0× tonnage, with 1.1× CNS load.

MY
Myo reps
One activation set, then short mini-sets with five breaths of rest.
You do one “activation” set of 10–15 reps close to failure, rest for about five deep breaths (10–20 seconds), then do several mini-sets of 3–5 reps with the same weight. The mini-sets are performed while the muscle is already fatigued, so nearly every rep is a hard, effective rep.
How to do it
Activation set: 10–15 reps to failure or RPE 9, with a weight you could normally do about 12 reps with.
Rest for five deep breaths, around 10–20 seconds.
Do a mini-set of 3–5 reps with the same weight.
Repeat the breaths and mini-sets for 3–5 rounds, or until you can no longer reach 3 reps.
When to use it
When time is short. One myo-rep set takes a few minutes and replaces several normal sets. Best on cables, machines and isolation work where you can reset instantly.
Watch out. Stay with stable movements that are safe to take close to failure. Heavy free-weight compounds and anything that loads the lower back are poor choices.
In Herculex
Tracks the activation set and every mini-set, with a counter for the planned mini-sets. All effective reps count towards volume.

P½
Partials
Half-range reps after you can no longer finish full ones.
Reps through only part of the range of motion, such as the bottom half of a curl, performed once full-range reps are no longer possible. Partials in the stretched (lengthened) position are especially popular for growth.
How to do it
Take a set to failure with full-range reps.
Without resting, keep going with half-range reps in the strongest or the most stretched part of the movement.
Stop when even partial reps stall.
When to use it
To squeeze extra work out of a muscle on the end of a set, particularly on machines and cables.
In Herculex
Because the mechanical work per rep is about half, Herculex counts partial reps at 0.5× tonnage so they do not inflate your volume.

N
Negatives
Lift with help, lower slowly for 3–5 seconds.
Reps that emphasise the eccentric (lowering) phase. Muscles are stronger when lengthening than when shortening, so you can lower more than you can lift. A negative is a slow, controlled lowering of 3–5 seconds, often with a weight above your normal limit.
How to do it
Get the weight to the top, with a spotter, a machine, or by using both limbs to lift it.
Lower it slowly and under full control, taking 3–5 seconds.
Reset and repeat for a few reps.
When to use it
To break through a strength plateau or to build size with fewer reps, usually near the end of a session.
Watch out. Heavy negatives cause a lot of muscle damage and soreness. Use a spotter for anything heavy, and do not use them every session.
In Herculex
Counted at 0.75× tonnage, with a high 1.3× CNS load so recovery advice accounts for the extra fatigue.
Tonnage0.75×
CNS load1.3×
F
Forced reps
A spotter helps you finish extra reps after failure.
When you reach failure under your own strength, a spotter gives just enough help to get past the sticking point so you can complete a few more reps.
How to do it
Perform the set until you cannot complete another rep unassisted.
Your spotter lifts just enough for you to finish two or three extra reps.
Control the lowering on every forced rep.
When to use it
Occasionally, on safe movements with a trusted spotter, such as a machine press or a dumbbell press.
Watch out. Needs a competent spotter, and is very taxing. Do not use it on a regular basis or on lifts where failure is dangerous.
In Herculex
Log your unassisted reps as normal; the assisted reps are added as “+ Forced”. Counted at 1.0× tonnage, with 1.3× CNS load.
Tonnage1×
CNS load1.3×
CR
Cheat reps
A little controlled body swing to get past the sticking point.
When strict reps stop, you use a small amount of body momentum to get past the hardest part and then lower the weight slowly and strictly.
How to do it
Do strict reps to failure.
Use a small, controlled swing to start the lift past the sticking point.
Lower the weight slowly. The lowering is where the muscle works.
When to use it
On safe isolation movements, such as curls or lateral raises, as a finishing technique.
Watch out. Keep the swing small. Using the lower back to heave the weight is how people get hurt.
In Herculex
Log your strict reps as normal; the momentum reps are added as “+ Cheat”. Cheat reps count at 0.85× tonnage, with 1.25× CNS load.
Tonnage0.85×
CNS load1.25×
PY
Pyramid set
Weight goes up while reps come down (or the reverse).
A series of sets in which weight goes up and reps go down from set to set (a pyramid), or weight goes down and reps go up (a reverse pyramid).
How to do it
Start with a lighter weight and higher reps.
Add weight and reduce reps on every set, finishing on your heaviest set.
For a reverse pyramid, start with the heaviest set and reduce the weight each time.
When to use it
To combine heavy and moderate work in one exercise, and to warm up progressively into the top set.
In Herculex
Each step is logged as its own set with its own weight and reps, at 1.0× tonnage.

21
21s
7 bottom-half reps, 7 top-half reps, 7 full reps, no rest.
A classic biceps-curl finisher done as one continuous set of 21 reps: 7 reps in the lower half of the range, 7 reps in the upper half and 7 full-range reps.
How to do it
Do 7 reps in the bottom half of the movement.
Straight away do 7 reps in the top half.
Finish with 7 full-range reps.
When to use it
As a pump-focused finisher on curls, leg extensions or triceps pushdowns.
Watch out. Use around 50–60% of your normal curl weight.
In Herculex
Recorded as one set of 21 reps at the chosen weight.

MD
Mechanical drop set
Change the leverage instead of the weight.
A drop set without touching the weights. At failure you switch to a variation that is easier to lift, such as a different grip, angle or stance, and continue with the same load.
How to do it
Start with the hardest variation of the exercise, for example an incline dumbbell press.
At failure, move straight to an easier position, such as a flat press, with the same dumbbells.
Finish in the easiest variation if you planned a third step.
When to use it
When there is no time or room to change the weights, such as with fixed dumbbells or a loaded barbell.
In Herculex
The full load is tracked through the variation. Counted at 1.0× tonnage.
Tonnage1×
CNS load1×
PE
Pre-exhaustion
An isolation exercise first, then the compound lift.
You fatigue a target muscle with an isolation movement and go straight to a compound exercise that trains it, so the muscle is the limiting factor and not a weaker helper.
How to do it
Do a set of the isolation exercise, such as a pec deck fly.
Move to the compound exercise straight away, such as a chest press.
Expect to use less weight on the compound than usual.
When to use it
When a smaller muscle (like the triceps in a bench press) tends to fail before the muscle you are trying to train.
In Herculex
Both movements are logged as normal sequential sets, at 1.0× tonnage.

20x
20 sets @ 60%
Twenty sets at 60% of your 1RM with short, strict rest.
A high-volume density protocol in the spirit of German Volume Training: 20 sets of the same lift at 60% of your one-rep max, with strict rest intervals.
How to do it
Work out 60% of your estimated 1RM for the lift.
Do all 20 sets with that weight, resting for the same short, timed interval every time.
Keep every rep clean. If form breaks down, stop.
When to use it
In a short, dedicated block for one lift, when you want to push volume.
Watch out. A great deal of work for a single lift. Do not run it alongside other heavy training for the same muscles.
In Herculex
Stores the percentage and the accumulated volume. Every set counts towards tonnage.

Timed & functional
Work measured against the clock instead of a rep target.
AM
AMRAP
As many reps (or rounds) as possible in a set time.
Complete as many repetitions or rounds as you can inside a fixed time cap, for example 60 seconds or 10 minutes. The result is your score.
How to do it
Set the time cap and start the clock.
Work through the prescribed movements, at a pace you can sustain.
When time is up, record your reps or rounds.
When to use it
For conditioning, benchmark tests, and finishing a session. Also as the last set of an exercise to test progress.
In Herculex
Stores the time cap and the completed reps or rounds. Tonnage is calculated from all completed reps.

EM
EMOM
Every minute on the minute, do the same work and rest what is left.
At the start of every minute you perform a prescribed number of reps. Whatever time is left in that minute is your rest. As the work takes longer, rest shrinks.
How to do it
Pick the movement, the reps per minute and the total number of minutes.
Start the clock and complete the reps as fast as you can with good form.
Rest until the next minute starts, then repeat.
When to use it
To control pacing and rest, to practise a skill under mild fatigue, or to do a fixed amount of work in a fixed time.
In Herculex
Tracks the total minutes and the reps per minute; each minute is logged as a mini-set.

FT
For time
Finish the prescribed work as fast as you can.
The work is fixed (for example 100 reps or a set list of movements) and you try to complete it in the shortest possible time. The stopwatch is your score.
How to do it
Define the exact work to be done.
Start the stopwatch and begin.
Stop the clock when the last rep is done.
When to use it
For conditioning and for measuring progress: repeat the same workout later and try to beat your time.
In Herculex
Records the elapsed time and whether you completed the work. Tonnage is counted as normal, with the time as the score.

Words used above
The short version of the terms these techniques lean on.
Failure
The point where you cannot complete another clean rep with good form. “Near failure” means one or two reps short of it.
RPE
Rate of perceived exertion, from 1 to 10. RPE 9 means you could have done one more rep; RPE 10 is failure.
RIR
Reps in reserve: how many reps you had left. RIR 1 is the same as RPE 9.
1RM
Your one-rep max, the heaviest weight you can lift once. Herculex estimates it from your sets.
Eccentric / concentric
The eccentric phase is the lowering, where the muscle lengthens under load. The concentric phase is the lifting.
Tonnage
Weight × reps added up across sets. Herculex uses it as one measure of training volume, adjusted per set type.
CNS load
How demanding a set is on your central nervous system. Herculex feeds it into the recovery model and deload advice.
Try them in a workout.
Tap the set number in an active workout to switch a set to any of these types. The same guide is in the app, in the exercise library and next to the set-type picker.
Herculex gives fitness guidance, not medical advice. Intensity techniques are demanding: build up gradually, use a spotter where it matters, and stop if something hurts.
