The Myo-reps card to take into the gym
| Phase | Action | Example | Stop |
|---|---|---|---|
| Exercise | Stable isolation, cable or machine | Seated leg curl | Do not begin if the movement already hurts |
| Activation | 9–12 reps near 1 RIR | 40 kg × 11 | No assistance, cheating or forced rep |
| Rest | 10–15 deep breaths | Roughly 20–30 s | Do not turn it into full recovery |
| Mini-set | 3 reps at the same load | 40 × 3 | Same range and control |
| Repeat | Rest + 3 reps | 3 + 3 + 3 | Close when rep three becomes very slow |
| Log | Activation + later reps | 40 × 11 +9 | Do not invent equivalence with straight sets |
Fagerli describes an activation set near the fatigue point without grinding an assisted rep, followed by short mini-sets with the same load. In his 9–12 +3x example, the sequence ends when the third rep becomes very difficult or the planned block is no longer completed. His tables are practical method guidelines, not a biological law or permission to ignore technique changes.
Where it fits and where risk wins
| Best first choice | May fit with experience | Avoid for the first trial | Why |
|---|---|---|---|
| Leg extension or curl | Leg press with safeties and control | Free squat | Fatigue changes bracing and path |
| Machine or cable lateral raise | Machine press | Heavy free overhead press | Stabilisers and exit become limiting |
| Arm curl or extension | Chest-supported row | Deadlift | Technical cost exceeds the saving |
| Pec deck or stable cable | Pulldown with solid technique | Fatigued bent-over row | Posture may fail before target muscle |
- Check the limiter
The target muscle should be what limits each mini-set. When breathing, grip or position gives out first, the sequence no longer answers its intended job.
- Protect the same load
Myo-reps keep load between activation and mini-sets. If you reduce it, the sequence moves toward a drop set and needs a different log.
- Stop on speed and technique
Do not wait for a failed rep under an awkward load. A very slow rep, shorter range or growing momentum closes the block.
- Let next session vote
When the following exercise or next exposure clearly falls, reduce mini-sets or return to straight sets.
What the evidence says and cannot say
| Evidence | Observation | Limit here |
|---|---|---|
| 2026 advanced-systems review | No overall hypertrophy superiority; modest rest-pause signal | Heterogeneous methods and protocols |
| Six-week rest-pause trial | Similar strength and one localised advantage | Eighteen people; not exact original Myo-reps |
| Eight-week drop/rest/traditional trial | Similar thigh hypertrophy between groups | Volume equated and small sample |
| RIR meta-regression | Closer estimated proximity linked to more size change | Exact relationship uncertain; RIR often estimated |
| Rest review | Large overlap between rest durations | Does not prove brief within-sequence rest |
The useful conclusion is quieter than many headlines: Myo-reps can efficiently concentrate demanding repetitions, but it has not earned the right to replace every set or promise more muscle. Pooled comparisons of advanced systems do not support general hypertrophy superiority, and individual studies are too specific to make one sequence universally optimal.
Three-exposure trial
Exposure 1 is 40 × 11 +9 in 2:10. Exposure 2 reaches 40 × 12 +9 in 2:05. Exposure 3 uses 42.5 × 9 +6 in 2:00, but the following curl falls 20%. Do not claim a record because load rose. Repeat 40–42.5 with fewer mini-sets or return to straight sets and see which preserves the rest of the session.
Log a sequence without fooling yourself
| Entry | Load | Reps | RIR or stop | Reading |
|---|---|---|---|---|
| Activation | 40 kg | 11 | 1 RIR | Main reference |
| Mini 1 | 40 kg | 3 | Controlled | Same load |
| Mini 2 | 40 kg | 3 | Last rep slow | Still complete |
| Mini 3 | 40 kg | 3 | Technical stop | Close sequence |
| Summary | 40 kg | 11 +9 | No forced failure | Compare next exposure |
BUSTAFIT records load, repetitions, RIR and history on iPhone. We do not claim a dedicated Myo-reps template. Logging activation and mini-sets as separate entries keeps load visible and prevents “11 +9” from looking like twenty continuous repetitions. It is an editorial convention using existing fields.
A useful video with its commercial context
Video summary
Dr. Milo Wolf gives an English-language, evidence-focused and deliberately sceptical view of Myo-reps. The video has automatic English captions; its description promotes coaching, free programs and apparel through the creator’s channels. BUSTAFIT did not commission it and has no commercial relationship with the channel. Treat it as interpretation and visual context, not as the source for this protocol.
The video is valuable precisely because it lowers the hype, but it remains a creator’s interpretation. The card above relies on Fagerli’s original description, and the evidence table keeps exact Myo-reps separate from broader rest-pause research.
