Supersets are age old. Since the very first time a weight was lifted in the gym, more likely than not, supersets were employed. They’re a time-honoured way of speeding up your workouts, training efficiently, and getting more bang for your buck out of your sessions. Essentially, they involve pairing two movements back-to-back, taking no rest between the two, then resting between rounds. For example, bench press straight into pull-ups, rest a couple of minutes, back to bench press.

Combo sets – or combination sets – work slightly differently.

They won’t necessarily save you more time in the gym. But they will mean you use exactly the same amount of time you would otherwise, and potentially build more muscle.

What is a Combination Set?

Like a superset, a combination set involves performing two exercises in succession. Unlike a superset, where you don’t rest between movements, with a combo set you rest between each movement as well as between each round. So you perform your bench press, rest for two minutes, perform your pull-ups, rest for two minutes, then back to bench press. Run that for four rounds and you’ve got four sets of each movement.

Why do Combination Sets Work?

Supersets are time-efficient, but they drive up central fatigue – fatigue across the whole system. Combination sets, on the other hand, take the same total rest time you’d use performing straight sets, but by alternating movements, each muscle group effectively gets longer to recover.

Think about it like this. If you perform bench press, rest two minutes, then go again, you’re only getting two minutes between sets. With a combination set – bench press, two minutes, chin-ups, two minutes, back to bench – you’re actually getting closer to four minutes between pressing efforts, plus however long your pulling set takes.

What to read next

You’re still working hard overall, but you get more local muscular recovery. Which means you can move more weight, create more tension, recruit more muscle fibres, and, all else being equal, build more muscle – from the same amount of time invested.

There’s growing evidence to support this approach. Research comparing traditional straight sets to alternating or paired set structures shows that spreading fatigue across different muscle groups can improve performance across sets, leading to higher total training volume. In simple terms: you can lift more, for more quality reps, giving your body a stronger signal to grow.

How to Use Them in The Real World

These can be a pain in commercial gyms. Reserving a bench and a pull-up bar – or a rack and a machine – isn’t exactly great etiquette. A smarter play is to pair a dumbbell movement with a station-based exercise.

For example: front squats in a rack, paired with dumbbell Romanian deadlifts. Perform your squats, rest two to three minutes, hit your RDLs, rest again, then back to squats. You’re getting the same volume of each lift, but with more recovery baked in.

They might not be as efficient as supersets for saving time. But when it comes to building muscle with the minutes you’ve got, combination sets are a seriously effective upgrade.
