Are You Lifting Too Heavy? Why More Weight Isn't Always Better

One of the easiest traps to fall into when strength training is thinking that heavier always means better.

You add another 5kg to the bar. You manage the reps. It feels hard. You feel like you've had a good session.

But what if that extra weight means you're doing fewer reps, accumulating less quality work and spending more time recovering between sets?

Sometimes, lifting a little less weight can actually be the better choice.

Strength training isn't a test of how much you can lift

When you're training a compound movement such as a squat, deadlift, bench press or row, there's a difference between testing your strength and building your strength.

If you're testing your strength, you're interested in how much you can lift for a particular number of reps.

If you're building your strength, the goal is to give your body enough of the right stimulus, consistently, over time.

That's where training volume comes in.

Let's use an example

Imagine you're working on a squat and your target is 8–10 reps.

You could choose:

80kg × 5 reps = 400kg of total volume

Or:

70kg × 10 reps = 700kg of total volume

The 80kg set is obviously heavier. And lifting heavier isn't inherently bad.

But if 80kg means you can't reach the prescribed rep range, your technique starts to deteriorate and you need considerably longer to recover between sets, you may actually be getting less productive work from your training.

The 70kg set allows you to complete the full 10 reps, maintain better quality and potentially perform more productive sets.

The aim isn't simply to move the heaviest weight possible.

The aim is to use an appropriate weight to produce high-quality work.

But doesn't this mean we should just lift lighter?

No.

This is where things get a little more nuanced.

There's also a point where reducing the weight too much means you're simply doing lots of easy reps that aren't particularly challenging.

That's where the idea of junk volume comes in.

If you can comfortably perform 20 reps but your programme calls for 8-10, doing multiple sets of 20 just because you want to accumulate more volume isn't necessarily going to make your training more effective.

So there are two extremes to avoid:

Too heavy: You can't hit the target reps, your technique suffers and you're spending too much time recovering from each set.

Too light: The sets aren't challenging enough and you're accumulating volume without enough stimulus.

The sweet spot is somewhere in the middle.

Find the weight that allows you to do good work

For most of your training, you want a weight that is challenging but manageable.

You should be able to complete the prescribed reps with good technique, while still feeling like you have worked hard.

That doesn't mean every set should feel easy.

Quite the opposite.

The final few reps should require effort, but there should still be a clear difference between "this is hard" and "I'm trying to survive this set."

This is particularly important when you're performing compound lifts.

Squats, deadlifts, presses, rows and similar movements place a lot of demand on your body. Going unnecessarily heavy can create a lot of fatigue without necessarily creating a proportionally better training stimulus.

Build strength rather than constantly testing it

If you're always trying to find the heaviest weight you can lift today, you're constantly testing your current ability.

But strength training works best when you think longer term.

You want to accumulate quality training sessions.

You want to practice the movement.

You want to gradually increase the amount of work you're capable of doing.

And eventually, the weight that once felt heavy becomes your warm-up weight.

That's progress.

Rather than asking:

"What's the heaviest I can lift today?"

A better question is:

"What's the appropriate weight for me to do this work well today?"

Over time, if you're consistently hitting your reps, maintaining good technique and recovering well, you can gradually increase the load.

That's progressive overload.

And that's how you build the foundations that allow you to lift heavier later.

Don't chase the number on the bar

There will always be a temptation to add another plate.

And sometimes that's exactly what you should do.

But heavier isn't automatically better, just as lighter isn't automatically better.

The goal is to find the sweet spot between load, reps, effort and quality.

Lift heavy enough to challenge yourself.

Lift light enough to perform the work properly.

Accumulate enough quality volume to create a reason for your body to adapt.

Then repeat the process consistently.

Because the goal of strength training isn't to prove how strong you are today.

It's to become stronger over time.
