If you want to get stronger, build muscle or simply become more capable in the gym, there is one principle sitting underneath pretty much everything we do:

Progressive overload.

It sounds slightly more complicated than it actually is.

Progressive overload simply means gradually asking your body to do a little more over time.

Your body is incredibly good at adapting. Give it a challenge, allow it to recover, and it becomes better prepared to deal with that challenge next time.

The problem is that once you’ve adapted, doing exactly the same thing forever gives your body very little reason to continue improving.

That’s where progressive overload comes in.

Progress doesn’t just mean adding weight

The most obvious example is getting stronger.

Imagine you start a training block bench pressing 40kg for 8 reps.

Over the following weeks you might progress to:

You’re gradually doing more work and becoming stronger.

But adding weight to the bar is only one way to progress.

Progressive overload can also mean:

• Performing more repetitions with the same weight

• Improving your technique

• Increasing your range of motion

• Performing the same work with better control

• Completing more total work

• Using a more challenging variation

• Performing the same work at a lower perceived effort

That last one is easily overlooked.

If you perform an exercise with exactly the same weight and reps as you did six weeks ago, but it now feels considerably easier, you’ve still improved.

Why don’t we just add weight every week?

Because unfortunately human beings aren’t quite that predictable.

You aren’t going to walk into the gym every Monday and magically be 2.5kg stronger than you were the Monday before.

Some weeks you’ll feel fantastic.

Some weeks you’ve slept badly, had a stressful day at work, haven’t eaten enough, or your children have spent the night testing exactly how little sleep a human being requires to function.

Performance fluctuates.

Progress also becomes slower as you become more experienced.

A complete beginner might be able to increase their weights almost every session. Someone who has trained consistently for several years might work for months for a relatively small improvement.

Both are making progress.

This is why we track your training

It’s very difficult to progressively overload something if we don’t know what you did last time.

That’s one of the reasons we encourage you to log your weights and results.

If your programme says:

3 sets of 8–10 reps

…and last week you completed:

20kg × 10 20kg × 10 20kg × 10

…with good technique and a couple of repetitions still available, that’s useful information.

This week we might increase the weight.

Alternatively, if last week you managed:

20kg × 10 20kg × 8 20kg × 6

…and the final set looked like you were attempting to wrestle the dumbbells rather than lift them, we probably don’t need to increase anything yet.

Do the current job better first.

Why we repeat exercises

This also explains why your Resolve programme contains exercises that repeat across several weeks.

Changing every exercise every session might feel varied and exciting, but it makes progression considerably harder to measure.

If you bench press once and don’t perform it again for six weeks, it’s difficult to know whether you’ve actually improved.

Instead, we deliberately keep important movements in your programme long enough for you to practise them, become more confident and progressively improve them.

Variation has its place.

But variation for the sake of variation isn’t progression.

More isn’t always better

Progressive overload doesn’t mean every session needs to be harder than the last.

Training creates fatigue as well as fitness.

Sometimes the smartest thing we can do is maintain a load, reduce the training stress or deliberately have an easier period so your body has an opportunity to recover.

That’s why our programmes include different phases and why we periodically deload.

The goal isn’t to win today’s workout.

The goal is to be better months and years from now.

What should you actually do?

Fortunately, you don’t need to spend your evenings calculating training volume on a spreadsheet.

That’s our job.

Your job is much simpler:

• Turn up consistently.

• Log what you do.

• Perform your exercises with the best technique you can.

• Challenge yourself appropriately.

• Listen to your coach when they tell you to add weight.

And occasionally listen to your coach when they tell you not to add weight — even though you’re absolutely convinced another 10kg will be fine.

Do those things consistently and progressive overload largely takes care of itself.

The takeaway

Your body adapts to what you repeatedly ask it to do.

If the challenge gradually increases over time, your body has a reason to continue adapting.

That doesn’t mean every workout needs to be heavier or harder.

Progress might mean more weight, more reps, better technique, greater control or simply making something that used to feel difficult feel easy.

Train consistently. Track what you’re doing. Give your body a reason to adapt.

That’s progressive overload.
