Supersets: Same Muscle in 25 Fewer Minutes (and the Pairing Mistake That Kills It)

"I don't have time to lift" might be the most common reason guys give for skipping the gym. This fall, a study gave that excuse a hard time. Men's Health ran it under the headline that supersets cut gym time by 36% without costing you muscle (Men's Health), and the time question has been all over X since, including a "20 minutes a day, which exercise wins?" post from a former NBA player that drew more than a million views (X).

Not everyone's sold. A clip of one creator calling supersets "a waste of time" made the rounds in October (X), and plenty of people still file them under cardio.

So who's right? Mostly the study, with one big catch that most posts skip: how you pair the exercises matters a lot.

What a superset actually is

A superset means doing a set of one exercise and then going straight into a set of a different exercise, with little or no rest between them. You rest after the pair, not after each set. Because you rest half as often, the workout gets shorter.

There are a few kinds. The one with the best evidence is the opposing-muscle superset, sometimes called agonist-antagonist: a push paired with a pull, or a front-of-the-leg move paired with a back-of-the-leg move. The other common kind stacks two exercises for the same muscle back to back, like bench press followed by dumbbell bench.

What the new study found

The trial behind the headlines was led by Ryan Burke and Brad Schoenfeld and published in Science & Sports in January 2026 (ScienceDirect). Some coverage said 50 lifters. Fifty volunteered, but 43 finished: 34 men and 9 women aged 18 to 40, all with at least a year of lifting experience (free preprint).

For eight weeks, both groups trained twice a week with the same six exercises: lat pulldown, Smith machine bench press, seated leg curl, leg extension, dumbbell curl and cable triceps pushdown. Everyone did 4 sets of 8 to 12 reps per exercise, taken to failure.

The traditional group rested 2 minutes between every set. The superset group paired pulldown with bench, leg curl with leg extension, and curls with pushdowns. They went from one exercise to the other in about 20 seconds, then rested 2 minutes after each pair.

The results, per the preprint:

• Same muscle growth. Both groups had similar increases in muscle thickness, measured with ultrasound.
• Same strength, power and endurance gains. Bench press max and the other tests improved about the same in both groups.
• Much shorter workouts. Superset sessions took 44.4 minutes on average, versus 69.1 minutes for traditional sets. That's about 25 minutes saved per workout, or 36%.
• Similar total work. Total weight lifted across a session was about the same.

This isn't a one-off, either. A 2025 meta-analysis in Sports Medicine pooled 19 studies with 313 participants and reached the same conclusion: supersets matched traditional sets for total reps, volume and long-term gains in strength and muscle size, in less time (Zhang et al., PubMed).

The pairing mistake that kills it

Here's the nuance. That same meta-analysis split supersets by type. When people paired opposing muscles, they actually completed more reps than with traditional sets. When they paired two exercises for the same muscle, total volume dropped, and by a large margin (Zhang et al., PubMed).

That makes sense when you think about it. If you bench and then go straight to dumbbell bench, your chest and triceps start the second exercise already tired, so you lift less. If you bench and then do a row, your back is fresh while your chest gets a break.

So if your "superset" is two chest exercises in a row, you're not getting the deal the study found. You're trading volume for time.

A 2025 review in the Journal of Strength and Conditioning Research came to a similar read: supersets produce similar results and save time, but power output tends to be better with traditional sets (Mang, Beam & Kravitz). If you're training to be explosive, keep your power work as straight sets.

What the hype leaves out

Supersets feel harder. In the Burke and Schoenfeld trial, people rated superset sessions about a point harder on a 10-point effort scale (8.1 vs 7.2). Nausea was common in both groups, and more common with supersets: 17 people reported it in the superset group versus 9 in the traditional group, along with a few cases of vomiting in each. The authors note these reports were collected from memory at the end of the study, so treat the exact numbers with caution (preprint). Their advice for people new to full-body supersets is to stop sets a little short of failure or do fewer sets at first, then build up.

It's one routine. The trial used mostly machines and single-joint leg exercises. The authors say outright that it doesn't tell us how supersets work with squats, deadlifts or leg presses. Applying it to heavy compound lifts is a guess, not a finding.

"Supersets are cardio" is partly true, for the wrong kind. No-rest circuits with light weights are a different workout. The trial used hard sets taken to failure with 2 minutes of rest after each pair, and that built muscle as well as straight sets.

"So I can do fewer sets" is not what it showed. Both groups did the same number of sets. The time came from cutting rest, not cutting work.

How to use supersets

• Pair opposing muscles. Push with pull (bench with row, overhead press with pulldown), front with back (leg extension with leg curl), or biceps with triceps.
• Keep the switch fast and the rest after the pair. The study used about 20 seconds between exercises and 2 minutes after each pair.
• Keep the sets hard. The gains came from real effort, not light pumping.
• Keep heavy or explosive lifts as straight sets if you want, and superset the accessory work around them.
• Plan around the gym. Holding two stations at 6pm is the real-world catch. Dumbbells, cables or two spots close together make it easier, though lifters in a r/GarageGym thread point out that changing plates on adjustable dumbbells slows things down.

The rest of the basics still apply. Muscle needs enough protein to grow, and we covered the numbers in How Much Protein Do You Actually Need to Build Muscle?

Time was never the real problem

A 45-minute workout twice a week built the same muscle as a 70-minute one in this study. For most guys, the barrier was never the 25 minutes. It's not having a plan and not holding a standard when the week gets busy. We wrote about that in You Don't Need a Reset. You Need a Standard.
