Drop sets
A drop set takes a set to failure, then immediately cuts the load and keeps going. It builds about as much muscle as traditional sets, not more, but it can get there in less time. Use it to save time, not as a growth shortcut.
What the science says
- Similar muscle growth to traditional sets Moderate evidence
A 2023 meta-analysis (Sødal et al., 5 studies pooled, 142 participants) found that drop sets and traditional sets both increased muscle size, with no significant difference between them. The studies were small and short, so the evidence is consistent but not deep.
- Same result in less session time Moderate evidence
The same meta-analysis noted that some drop-set protocols took one-half to one-third of the time of the traditional comparison. That time saving, not extra growth, is the real advantage.
- No hypertrophy edge when volume and effort are matched Moderate evidence
Enes et al. (2021) equalized total volume in trained men and found no difference in thigh muscle growth between drop sets, rest-pause and traditional sets. A 2026 meta-analysis of advanced training systems (Tsartsapakis et al., 23 studies) likewise found drop sets comparable to traditional sets when volume and effort were matched.
How to apply it
Use drop sets on the last set of one or two exercises, on equipment where changing the load is fast.
Who should be careful
Training to failure repeatedly raises fatigue and soreness; avoid drop sets on heavy free-weight lifts like squats or deadlifts where technique breaks down under fatigue. Beginners should first learn the basic lifts. If you have a medical condition or injury, check with a qualified health professional before training to failure.
Frequently asked questions
Do drop sets build more muscle than normal sets?
No. A 2023 meta-analysis found similar muscle growth with drop sets and traditional sets; the difference was not significant.
So why use drop sets at all?
To save time. Some drop-set protocols took one-half to one-third of the session time of traditional sets for a similar result.
How many drops should I do?
One to three drops, cutting the load by about 20–30% each time with little or no rest, on the last set of one or two exercises.

More training methods
- Rest-pause sets (including myo-reps) Limited evidence
Rest-pause means taking a set close to failure, resting 15–30 seconds, then squeezing out a few more reps, repeated a few times.
- Supersets Moderate evidence
A superset pairs two exercises back to back with little or no rest.
- High-intensity interval training (HIIT) Strong evidence
HIIT alternates short hard efforts with recovery.
- Zone 2 training Limited evidence
Easy, steady cardio clearly improves fitness and health, but the popular claim that "Zone 2" is a special, optimal intensity for building mitochondria and burning fat is not supported.
- Fasted training (fasted cardio) Limited evidence
Training on an empty stomach burns more fat during the session, but that does not translate into more fat lost over weeks.
- Static stretching before training Limited evidence
Holding long static stretches right before lifting or sprinting slightly lowers strength and power, and it has not been shown to prevent injuries.
