Reps drop every set: is 10, 8, 6 normal?

By Louis Ferret, founder of PrimeFeat · About · Updated on November 5, 2026

Yes, it is normal. If you use the same weight and push your sets hard, you will usually lose reps from one set to the next, so 10, 8, 6 is a common result. It only becomes a problem when the drop is so steep that your last sets do little, and the first thing to check then is your rest time.

Yes, it is normal

Many beginners open their log, see 10, 8, 6, and think something went wrong. A program may say 3 x 10, so anything else looks like failure. But matching reps on every set at the same weight usually means the first sets were well short of your limit. If you go hard on set one, sets two and three will come in lower.

A falling pattern tells you two useful things: the weight is challenging, and you are putting in real effort. What you do with it depends on your target and on how steep the fall is.

Why reps fall from set to set

The short version is fatigue. A hard set tires your muscles, and a rest of a few minutes does not bring them all the way back. So you start each new set with a little less in the tank, and you reach your limit sooner.

Three things make the drop bigger:

Not all of this is about muscles. If you feel out of breath or your grip gives out, your target muscle may have more to give than the rep count suggests.

How much drop-off is fine

There is no agreed number here, and we did not find a study that sets one. As a rule of thumb, losing 1 or 2 reps per set on a hard exercise is ordinary. Losing half your reps by the second set suggests you went too hard on the first or rested too little.

What matters more is how your sets compare with your target. The same 10, 8, 6 means different things depending on what you were aiming for. Here it is under the rule our app uses (you can read the full rule in how much weight to add):

TargetIs 10, 8, 6 on target?Next workout
3 x 6Every set reached 6Add weight
3 x 8Last set fell short, average is 8Same weight
3 x 10Average is 8, exactly 80% of the targetSame weight, only just
3 x 12Average is 8, under 80% of the target (9.6)Lower the weight by one step
Range of 6 to 10Every set reached 6, not all reached 10Same weight, aim for one more rep

So the pattern on its own is not the verdict. A set of 6 is a win if you aimed for 6. Here are three examples of how that plays out:

If your drop-off is steady but you keep falling short of your target, read whether to repeat the weight or drop it.

When to lower the weight between sets

You do not have to keep the same weight to the end. Lowering it between sets is a normal tool, and some programs plan it on purpose. It makes sense in these cases:

For example, on a bench press: 135 lb (about 61 kg) x 10, 135 lb x 8, then 115 lb (about 52 kg) x 10. Take off about 10 to 15%, then see how it goes. That figure is a rule of thumb too.

There is one downside. If you lower the weight every workout, it gets harder to compare sessions, so do it the same way each time. And in our app, the next suggestion takes its weight from your last set, so a lighter last set will pull the suggestion down with it. Adjust it by hand if you know your main weight has not changed.

If the drop comes with pain instead of tiredness, stop the exercise and see a doctor or physical therapist.

Rest time: the first thing to check

Before you change the weight, time your rest. Many people think they rest 2 minutes when it is really closer to 1, or the opposite when they are on their phone. A timer takes the guesswork out.

Research supports this. A 2009 review of 35 studies found that with loads between 50 and 90% of your one-rep max, resting 3 to 5 minutes allowed more reps over multiple sets. In a small 2016 trial, 21 young trained men did the same 8-week program with either 1 or 3 minutes of rest. The 3-minute group gained more strength on the squat and bench press, and more thigh muscle thickness. That was one small group of experienced men, so it does not settle the question for everyone.

What this means in practice:

Take a simple test. If your usual rest gives you 10, 8, 6, add a minute and repeat the workout. If you get 10, 9, 8, rest was probably the main cause and you may not need to change the weight.

How to count progress when your sets differ

Comparing 10, 8, 6 with 10, 9, 7 is easy. Comparing different weights is less so. Two simple numbers help:

WorkoutWeightRepsTotal repsTonnage
A100 lb (45 kg)10, 8, 6242,400 lb (1,080 kg)
B100 lb (45 kg)10, 9, 7262,600 lb (1,170 kg)
C110 lb (50 kg)8, 7, 6212,310 lb (1,050 kg)

From A to B, the answer is clear: same weight, more reps, more tonnage. That is progress.

C is the interesting one. Tonnage went down, but the weight went up, so it is not a bad workout. It is normal for tonnage to dip when you move up. Compare C with the next workout at 110 lb instead of with B. To compare across different weights, you can also put your best set into a 1RM calculator. With the Epley formula, 100 lb x 10 gives about 133 lb and 110 lb x 8 gives about 139 lb, or about 60 and 63 kg with the kg figures. That points to a stronger top set, but it is only an estimate.

Count working sets only, because warm-ups would inflate your numbers. PrimeFeat works out the tonnage of each workout and leaves warm-ups out, so a free workout tracker can do this part for you. Otherwise, any workout log and a calculator will do. For the bigger picture, see how to track progressive overload.

FAQ

Should I aim for the same reps on every set?

You can, but it is not required. Matching reps at the same weight usually means you are stopping well short of your limit on the first sets. That is a fine way to train, and many programs ask for it. Just use the rep target of your program to decide.

Do I have to go to failure on every set?

No. You can stop a rep or two before failure on most sets and still train hard. Saving failure for the last set, if you use it at all, usually protects your reps on the sets before it.

Is it better to do 10, 8, 6 or use less weight and get 8, 8, 8?

Neither is always better. Match it to your target. If your program asks for 3 x 8, the lighter weight that gets you 8, 8, 8 is the right one, and you can add weight once it feels easier.

Does a pyramid mean the same thing as dropping reps?

Not quite. In a pyramid, you change the weight on purpose, so reps fall because the load goes up. Here, the weight stays the same and reps fall because of fatigue. Log them the same way, but do not compare one with the other.
