What is a drop set, and how do you do one?
A drop set is one set that keeps going after you would normally stop. You lift until you cannot do another clean rep, immediately lower the weight, and keep repping with no rest. You can drop once or several times. It is a way to squeeze more work out of the last set of an exercise, and it works best on machines, dumbbells and isolation lifts. This guide covers how to do one, how much to drop, where it fits, and how to write it down without messing up your records.

What a drop set is
A normal set ends when you reach your target reps or when the next rep would fail. A drop set does not end there. The moment you cannot do another rep with good form, you lower the weight by a chunk and keep going until you reach that point again. That is one drop. Do it again and you have two drops. Each drop takes only as long as it takes to move the pin or pick up the next dumbbell.
The reason people use drop sets is time. In one long set you take a muscle through two or three rounds of hard reps, which would otherwise take three sets and six minutes of rest. The cost is fatigue, so a drop set belongs on the last set of an exercise, and the sets before it stay normal.
How to do a drop set
- Pick an exercise where the weight can change fast. A pin-loaded machine, a cable stack or a row of dumbbells. Set up the lighter weights before you start.
- Do your working set as normal. Use your usual weight and stop one rep short of failure, or at failure if the exercise is safe for it. For a lateral raise, that is the 12 kg (25 lb) dumbbells for 12 reps.
- Drop the weight at once. Lower it by about 20%, so the 12 kg dumbbells become 10 kg (20 lb). Take no rest beyond the time it takes to swap.
- Rep to the same point again. You will get fewer reps than before. That is expected. Eight to ten reps at 10 kg is a good drop.
- Drop again if the plan calls for it. Down to 8 kg (15 lb) for as many reps as you can. Two drops is a common stopping point. Three is a lot.
- Stop, and write all of it down. The working set and each drop, with its own weight and reps. The logging section below covers how.
How much weight to drop
A common range is 10 to 30% per drop. Smaller drops keep the reps low and the set heavy. Bigger drops let you get more reps but feel lighter and burn more than they build. One to three drops is a common range for the number of drops. Beyond that, the weight is so light that the extra reps do not add much.
The exact number depends on the equipment. A machine with 5 kg plates lets you drop by one or two plates. Dumbbells usually step by 2 kg or 2.5 kg at the lighter end, so the drop is whatever the next pair gives you. Aim for the range and do not fuss over the exact percentage.
| Weight | Reps | Note | |
|---|---|---|---|
| Working set | 30 kg (65 lb) | 10 | This is the number that counts for your records |
| Drop 1 | 24 kg (55 lb) | 8 | About 20% off, no rest |
| Drop 2 | 18 kg (40 lb) | 9 | About 25% off, no rest |
Where drop sets fit, and where they do not
Drop sets add fatigue fast, so they belong at the end of an exercise, and usually at the end of the session. Use them on the last set only, and on the lifts where safety and speed of weight change are on your side.
- Good: the last set of an exercise, when the working sets are already done.
- Good: machines and cables, where you move a pin and keep going.
- Good: dumbbell isolation work like curls, lateral raises and triceps extensions.
- Good: when you are short on time and want more work from fewer sets.
- Not good: heavy barbell squats, deadlifts and bench presses. Stripping plates is slow, form breaks down when tired, and the fatigue hurts the rest of the session.
- Not good: on every set of every exercise. Once or twice a session is plenty.
Drop set vs superset vs rest-pause
These three get mixed up because all of them squeeze more work into less time. They are different tools.
| Drop set | Superset | Rest-pause | |
|---|---|---|---|
| What changes | The weight goes down | The exercise changes | Nothing, you pause and continue |
| Rest | None | None between the two exercises | 10 to 20 seconds |
| Example | Curl 30 kg to failure, then 24 kg, then 18 kg | Curl 30 kg, then straight into triceps pushdowns | Curl 30 kg to failure, rest 15 seconds, 3 more reps, rest, 2 more |
| Best for | Isolation and machines | Pairing opposite muscles to save time | Getting extra reps at one heavy weight |
How to log a drop set so your records stay clean
The trap with drop sets is the record. If your log shows 30 kg for 10, then 24 for 8, then 18 for 9 as three plain sets, your average weight for the exercise just fell and your app may think you got weaker. The fix is to mark the drops as drops. The first heavy set is the working weight. The drops are extra work that belongs to it.
In SayLift, a set can be marked as a warm-up (W), a drop set (D) or to failure (F). A set marked D is logged with its own weight and reps, so you can repeat it next week, but it is not treated as a new working set. Your working weight stays the 30 kg set. Warm-ups never count toward records either, which do warm-up sets count explains.
By voice, you just say it the way it happened: "cable curls, three sets of ten at 30, then a drop set at 24 for 8, then a drop set at 18 for 9". The AI writes each set to the review screen with the drops marked, you check it and save. Logging by hand, you tap the set kind on each row. Either way, the coach reads your working sets, and the drops stay out of the way. If you also want to record how hard the working set was, reps in reserve covers that note.
Who SayLift is for
SayLift is for iPhone lifters who use drop sets and still want a clean record of what they lift. Say the session when it is done, including the drops, and the app keeps your working weight, your records and the coach's next-weight suggestion all based on the sets that count. Workout apps that track warm-up and drop sets shows how it compares.
It costs $4.17 a month (billed $49.99 a year), $7.99 a month or $3.99 a week after a 3-day free trial. Get SayLift on the App Store.
Frequently asked questions
What is a drop set in the gym?
A drop set is one set that continues after you reach failure. You lower the weight straight away, usually by 10 to 30%, and keep going with no rest until you reach that point again. You can drop once or several times.
Are drop sets good for building muscle?
They are a useful way to get more hard reps in less time, which is what muscle growth needs. They are not better than normal sets rep for rep, and they add fatigue fast. Most people use them on the last set of an isolation exercise rather than throughout a session.
How many drop sets should I do in a workout?
One or two is a common range. Drop sets are tiring, and doing them on every exercise makes the later part of the session suffer. Put them on the last set of the lifts where the weight is easy to change.
What is the difference between a drop set and a superset?
In a drop set you keep the same exercise and lower the weight. In a superset you keep going but switch to a different exercise, often for the opposite muscle. Both skip the rest, but only the drop set changes the load.
Do drop sets count as one set or several?
Count the first heavy set as your working set, and the drops as extra work that belongs to it. For records and progression, only the working set matters. For total work done, the drops add up too, so log each one with its own weight and reps.
How do I log a drop set in SayLift?
Say it: "then a drop set at 20 for 12". The AI adds the set with its own weight and reps and marks it as a drop set with a D. Logging by hand, you tap the set kind on the row. Drop sets are kept out of your working weight, so the coach and your records read the sets that count.
Stop typing between sets
Say what you lifted. SayLift writes down every set, rep and weight, then tells you what to lift next time. Say what you ate and it counts the calories too. iPhone only, 3 days free then $4.17 a month, billed $49.99 a year.
