Drop set: what it is and how to do it right

A drop set is a set where you train to failure or close to it, then immediately lower the weight by about 20 to 30 % and keep going without rest, often for one to three drops. It packs a lot of hard work into very little time. Research suggests drop sets build about as much muscle as regular sets with matched volume, so their main benefit is efficiency.

Drop set meaning

The drop set definition is simple: one exercise, several weights, no rest in between. You start with a weight you can lift for your target reps, reach failure or one rep short of it, strip some weight, and continue. The lighter weight lets your tired muscle produce more reps, so you extend the set past the point where it would normally end.

It is sometimes called stripping, running the rack or a descending set. On a dumbbell rack you literally walk down the rack; on a machine you move the pin; with a barbell, training partners pull plates off each side.

How to do a drop set

  1. Pick the right exerciseMachines, cables and dumbbells. Changing the weight must take seconds, and failing must be safe.
  2. Do your normal last setUse your usual working weight and take it to failure or about one rep short, with good form.
  3. Drop 20 to 30 % of the weightThat is a rule of thumb, not a law. A smaller drop gives fewer extra reps; a bigger drop gives more.
  4. Continue straight awayRest no more than the 5 to 10 seconds it takes to change the weight, then go to failure or close to it again.
  5. Repeat once or twice, then stopOne or two drops cover most of the benefit. Write down the reps for each drop so next time has a target.
Do it on the last set only. Put the drop set at the end of an exercise, and use it on one or two exercises per session. Doing it on every set makes the rest of your workout worse.

Drop set example: lateral raise

The lateral raise is one of the most searched drop set exercises, and it suits the method well: light dumbbells, a small muscle, and nothing dangerous about failing. Here is a typical lateral raise drop set as the last of three sets.

Lateral raise drop set (last set)
PartWeightRepsRest
Main set12 kg (25 lb)12 to 15, near failureNone
Drop 19 kg (20 lb)As many good reps as possibleNone
Drop 26 kg (15 lb)As many good reps as possibleDone

That is a triple drop set if you count the main set and two drops, though some people use the name only when there are three drops after the main set. Either way, your side delts get a lot of work in about a minute. More shoulder options are in the shoulder workout guide.

Mechanical drop set

A mechanical drop set keeps the same weight but switches to an easier version of the exercise when you hit failure. You change the leverage instead of the load, so it works even when you only have one pair of dumbbells.

Mechanical drop set examples
Start withThen switch toThen (optional)
Lateral raise, straight armsLateral raise, bent elbowsPartial reps from the bottom
Incline dumbbell pressFlat dumbbell pressClose grip dumbbell press
Decline or feet-up push upRegular push upIncline push up
Wide grip pull upChin upNegatives only

The lateral raise mechanical drop set is popular for a reason: bending the elbows shortens the lever, so the same dumbbells suddenly feel lighter and you can squeeze out several more reps.

Drop set benefits: what the research says

A 2023 systematic review and meta-analysis by Sødal and colleagues in Sports Medicine Open compared drop sets with traditional sets for muscle growth. Both approaches built muscle, and the difference between them was not significant. The authors noted that drop set protocols took less time, which makes them an option for people who are short on time.

So the honest summary of drop set benefits is this: they are not a secret to extra growth, but they are an efficient way to do hard sets. Drop set for hypertrophy works because it adds close to failure work to a muscle quickly. The downside is fatigue: they are demanding, and too many drop sets can eat into your recovery. Our hypertrophy guide covers the bigger picture of what drives growth.

  • Good for: saving time, small muscles like delts and arms, machine work at the end of a session, and adding a few extra hard reps when you are short on sets.
  • Less useful for: maximal strength, heavy compound lifts and beginners who still need practice at lifting with good technique.

Best drop set exercises

Exercises that suit drop sets
MuscleExerciseWhy it works
ShouldersLateral raiseLight dumbbells, quick to change
QuadsLeg extensionMove the pin in seconds; leg extension drop set burns the quads
HamstringsLeg curlMachine, safe to fail
ChestChest press machineNo spotter needed
BackLat pulldownPin stack, stable
BicepsCable curlCable curl drop set on a stack is quick and smooth
TricepsTricep pushdownSame cable, just move the pin

Avoid drop sets on barbell squats, deadlifts and bench presses without a spotter. Failing there is risky, and form tends to break down well before the muscle is truly done. For a cable based arm session that uses them, see the cable bicep workout.

Drop set vs superset

EffortTo or near failure, several timesNormal hard sets
Main useExtra hard work for one muscleSaving time across two muscles
FatigueHighModerate

Both save time, but in different ways. A superset fills your rest period with another exercise; a drop set removes the rest period from one exercise. You can use both in the same workout: supersets for the main work, then a drop set as a finisher.

A drop set workout and how to progress it

Keep progression simple: progress the main set, not the drops. Use the same rep range and the same rules you use for your other exercises, and let the drops fall where they fall. If the main set of leg extensions goes from 10 to 12 reps at the same weight, that is progress; the drops will follow.

Example drop set workout, upper body finisher (after your main lifts)
ExerciseSets x repsDrop set
Chest press machine3 x 8 to 12Last set, 1 drop
Lat pulldown3 x 8 to 12Last set, 1 drop
Lateral raise3 x 12 to 15Last set, 2 drops
Tricep pushdown2 x 10 to 15Last set, 1 drop

If you feel run down after a few weeks of this, cut back to one drop set per session, or take a deload week. To pick a sensible rep range for the main set, see the rep ranges guide.

Gripp

Progress the set that matters

Gripp logs the reps and weight of every set and sets your target for next session: last time 7 reps at 105 kg, today go for 8. Track your main set there and the drops become a bonus on top of real, measurable progress. Gripp is coming soon to iPhone.

Questions people ask

What is a drop set in weight training?
It is one set extended with lighter weights: you lift to failure or close to it, reduce the weight by roughly 20 to 30 %, and keep going without resting. Most people do one or two drops.
How much weight should I drop in a drop set?
A common rule of thumb is 20 to 30 % per drop. On dumbbells, that often means going down two or three pairs; on a machine, two or three pin positions.
Are drop sets better than normal sets?
Not for growth on their own. Research finds similar muscle growth when the volume is comparable. Drop sets are mainly a time saver and a way to add hard work to a small muscle.
How often should I do drop sets?
On the last set of one or two exercises per session is plenty. Using them on every set or every workout adds a lot of fatigue for little extra benefit.
Can beginners do drop sets?
They can on machines, but they rarely need to. Normal sets with steady progression already work very well in your first months of training.
