Time savedStrong evidence
In a meta-analysis, sessions were about 37% shorter on average; how much you save depends on how you arrange your rest. In single studies, a 42-minute session took 24 minutes as supersets and 18 as tri-sets, a whole-body session took 35 minutes instead of 58 (with about 4% fewer reps), and pre-exhaust pairs cut about a third. In plain terms, expect a third to a half off.

The same work, if the moves don't competeEmerging evidence
Across 19 studies with 313 people, supersets of moves that don't compete kept the total reps and the total weight lifted the same as normal sets, so more work got done per minute. Push-pull pairs even allowed a few more reps in two studies, though the certainty is low.

Same-muscle pairs cost you workEmerging evidence
Two moves for the same muscle cut the weight people could lift in two studies. In an 8-week trial of pre-exhaust pairs in 41 trained adults, people lifted about 30% more weight in total with normal sets, and muscle grew about the same with the pairs, slightly less on average, with wide uncertainty.

Long-term strength and muscleEmerging evidence
In the few long-term trials, strength (3 studies), muscular endurance (2) and muscle size (2) changed about as much with supersets as with normal sets, on moderate-certainty evidence, and in a 2026 network meta-analysis, all 3 superset studies of strength found no difference. In 17 men, alternating squats and bench presses for 6 weeks matched normal sets for strength and jumping, and in 15 trained men, alternating bench presses and bench pulls for 8 weeks matched separate sets in about half the time.
One 10-week trial of whole-body supersets twice a week (we read only its abstract) found slightly smaller strength gains on the pulldown, about 5 kg, with similar gains on the leg press and bench press.

They feel harderStrong evidence
Effort ratings were clearly higher with supersets, on high-certainty evidence. In 29 trained adults doing a whole-body session, effort was about 1.3 points higher and discomfort about 1 point higher.

Lactate and caloriesEmerging evidence
Lactate during and after a session was higher, and energy use per minute rose, in women and in men. But for the same work, total energy use was about the same in 10 young men, and the extra afterburn was roughly 5 kcal (our arithmetic from the study's figures).

Blood pressure and muscle damageMixed evidence
Blood pressure after a session was similar to normal sets, on low-certainty evidence, and pooled markers of muscle damage weren't higher. One high-volume study in 14 rugby players found creatine kinase (a marker of muscle damage) was likely higher, and jump height still down, 24 hours after supersets and tri-sets, when jump height had recovered after normal sets.

EnjoymentEmerging evidence
Enjoyment was the same as with normal sets, and 18 of 29 trained adults (15 women and 14 men) preferred supersets, mainly for the time saved and the feeling of working hard.

Who was studiedStrong evidence
Of 313 people in the meta-analysis, 232 were men and 66 women, mostly young and trained. We found no long-term superset trials in older adults or beginners, so the findings may not apply to everyone.
