A 12-week evidence-based guide to building strength and power with minimal volume
TL;DR
Single set training is effective. It is great for working parents or anyone lacking motivation to go to the gym for 1 hour+. It’s also great for athletes who want to build strength and power, without overtraining.
In fact, if you are an MMA fighter, one set training may be more effective than multiple sets in my opinion. Consider the “add-on protocol” – warm up and do a single set of plyometrics and a single set of resistance training 10 minutes before your actual MMA training. No need to go back to the gym etc.
Introduction
In today’s fitness landscape, maximising training efficiency is a common goal. Two popular methods—single set resistance training and single set plyometrics—offer effective results with minimal time commitment. This guide reviews the science behind these approaches, focusing on the minimum effective dose (MED) and optimal protocols over 12 weeks.
Whether you are a beginner or aiming to optimise your routine, understanding these principles will help you make informed choices. You will also find practical tips to support your progress.
Single Set Resistance Training Studies
What Is Single Set Resistance Training?
Single set resistance training involves performing one set of each exercise per workout. Unlike traditional multiple-set routines, it reduces training volume while maintaining or improving strength and muscle mass. This method suits those with limited time who want to sustain fitness gains.
Scientific Evidence on Effectiveness
Research shows single set training can produce significant strength and hypertrophy gains, especially for beginners and intermediate trainees (Schoenfeld et al., 2016; Krieger, 2010). For example, Krieger’s (2010) meta-analysis found that although multiple sets yield slightly greater gains, single set training achieves about 85–90% of those improvements. This highlights a favourable cost-benefit ratio for time-pressed individuals.
Rhea et al. (2003) demonstrated that single set training over 12 weeks effectively improves muscular strength in novice lifters. However, advanced athletes may need higher volume to continue progressing.
Minimum Effective Dose (MED) for Resistance Training
MED refers to the smallest training amount needed for measurable results. For resistance training, studies suggest performing one set to failure, 2–3 times per week, as a practical starting point (Fisher et al., 2011). Key points include:
- Focus on compound exercises like squats, deadlifts, presses, and rows.
- Perform 8–12 repetitions per set with proper form and controlled tempo.
- Apply progressive overload by gradually increasing weights or reps.
This approach fits busy schedules and lowers the risk of overtraining, making it sustainable.
Optimal Protocols for 12 Weeks
For best results over 12 weeks, follow these guidelines:
- Train 2–3 times weekly with full-body workouts.
- Perform 1 set per exercise to near failure (1–2 reps shy of failure).
- Include 6–8 exercises per session targeting major muscle groups.
- Gradually increase load or repetitions every 1–2 weeks.
- Rest 1–2 minutes between exercises.
Tracking progress with a training log or app is essential to monitor weights, reps, and effort.
Single Set Plyometrics Effectiveness
Understanding Plyometrics
Plyometrics involve explosive movements that enhance power, speed, and neuromuscular efficiency. Common exercises include jump squats, bounding, box jumps, and medicine ball throws. Plyometrics are widely used in athletic training and rehabilitation.
Research on Single Set Plyometrics
Most plyometric studies use multiple sets and high volume. However, recent research explores minimal plyometric doses for effective gains.
Markovic and Mikulic (2010) found that low-volume plyometric training (single set, 1–2 sessions per week) improved vertical jump height and sprint times over 6–12 weeks in recreational athletes. Chelly et al. (2014) showed that single set plyometric drills performed thrice weekly increased lower limb power by about 10% in youth soccer players after 8 weeks.
Minimum Effective Dose for Plyometrics
For time-efficient plyometric training:
- Perform 1–2 sets of 5–10 reps per exercise.
- Include 3–5 exercises targeting different muscle groups.
- Train 2–3 times per week with at least 48 hours between sessions.
- Emphasise technique and controlled landing to prevent injury.
This minimal approach can still improve power and explosive performance.
Optimal Plyometric Program Over 12 Weeks
To maximise benefits, gradually increase intensity and complexity:
- Weeks 1–4: Start with low-impact drills (e.g., skipping, low box jumps).
- Weeks 5–8: Progress to higher-impact, multi-directional exercises (e.g., bounding, depth jumps).
- Weeks 9–12: Integrate sport-specific plyometrics and increase jump height or distance.
Rest and recovery are critical. Using quality plyometric boxes and mats provides stable, safe surfaces during training.
Flexibility & Mobility: The Minimum Effective Dose
What Does the Research Say?
A landmark 2024 meta-analysis by Ingram et al. (University of South Australia), drawing on 189 studies and over 6,600 adults, found that flexibility follows the same “minimum effective dose” principle as strength training. The results were clear: improvements in flexibility maxed out at roughly 3 minutes per muscle per session, and around 8–10 minutes per muscle per week. Beyond that, no additional benefit was observed.
Critically, stretching to the point of discomfort or pain was also shown to be unnecessary — it added no further benefit. And improvements occurred regardless of the person’s age, sex, or training status. The only moderator was baseline flexibility: people who were tighter to begin with saw the biggest gains.
Practical Flexibility Guidelines
The earlier Bandy & Irion (1994) study found that holding a stretch for 30 seconds produced the same flexibility gains as holding for 60 seconds — and both were significantly better than 15 seconds, which was no different from not stretching at all. The ACSM recommends static stretching at least 2–3 days per week, holding each stretch 15–30 seconds, repeated 2–4 times.
The takeaway mirrors single-set strength training: frequency trumps duration. Short daily stretching outperforms occasional long sessions. A total of 5–8 minutes of targeted stretching per day is enough for meaningful results.
🧘 Flexibility MED at a Glance
- Hold duration: 30–60 seconds per stretch (no benefit beyond 60s)
- Volume ceiling: ~3 minutes per muscle per session / ~8–10 min per muscle per week
- Frequency: Daily short holds > weekly long sessions
- Intensity: Moderate — pain is unnecessary and adds no benefit
- Biggest responders: Those with poor baseline flexibility
Practical Tips for Combining Single Set Resistance, Plyometrics & Mobility
- Alternate days between resistance and plyometric sessions to allow recovery.
- Warm up thoroughly with dynamic stretches and low-intensity movements.
- Use resistance bands for warm-ups or accessory work to enhance activation.
- Monitor fatigue and adjust volume if you experience prolonged soreness or performance drops.
- Maintain proper nutrition and hydration to support recovery and adaptation.
- Tack on 5–8 minutes of static stretching at the end of every session — your flexibility MED is built in, not a separate workout.
The “Add-On Protocol” for Combat Athletes
If you train MMA, BJJ, Muay Thai, or any combat sport 3–5 times per week, you probably don’t want (or need) separate gym sessions. The add-on protocol solves this: arrive 10–15 minutes before your main training session, and bolt on a single set of plyometrics plus a single set of resistance work.
The logic is simple. Research on well-trained MMA athletes shows that low-volume, high-intensity strength and conditioning programmes outperform traditional high-volume circuits for improving 1RM strength, sprint speed, jump power, and even aerobic capacity — all in as little as 4 weeks (Kostikiadis et al., 2018). You don’t need marathon gym sessions. You need well-chosen exercises performed with intent.
How It Works
- Arrive 10–15 min early. Complete a quick dynamic warm-up (2–3 minutes).
- 1 set of plyometrics — e.g., 5–8 box jumps or med ball slams. Explosive, technical, done.
- 1 set of resistance — e.g., 6–10 reps of a compound lift or heavy band/machine exercise to near failure.
- Then go straight into your main MMA/BJJ/striking session.
- Finish with 5 min of static stretching on your tightest areas (hips, hamstrings, shoulders).
⚠️ CNS & Fatigue Warnings
- Don’t overdo it. The add-on is 1 set each, not a full workout. If you’re gassed before you even step on the mats, you’ve done too much. The goal is to potentiate performance, not wreck it.
- Watch your CNS. Heavy compound lifts (barbell squats, deadlifts) before combat training can tax the central nervous system significantly. If you find your reaction time, coordination, or sparring performance suffering, scale back.
- Consider machines or bands over free weights. After an explosive plyo set, your stabiliser muscles will be partially fatigued. Machines and resistance bands reduce the demand on stabilisers and lower injury risk — a leg press or banded squat may be smarter than a loaded barbell back squat in this context.
- Periodise around fight camp. During heavy sparring weeks or fight camp, reduce or drop the add-on. Skill work and recovery take priority. Use the add-on during base-building and off-season phases.

All resistance exercises: 1 working set to near failure (1–2 RIR) after 1–2 warm-up ramp sets. Total weekly commitment: ~2 hours including mobility.
Example Weekly Programme: MMA Fighter (Add-On Protocol)
This programme wraps strength, power, and mobility around 4 evening MMA sessions per week. The add-on work is done 10–15 minutes before you step on the mats. No separate gym visits needed.
| Day | Pre-Session Add-On (10–15 min) | Main Session (evening) | Post-Session Mobility |
|---|---|---|---|
| Monday | Plyo: Box Jumps × 6 Strength: Banded Squat or Leg Press × 8–10 |
MMA / Striking | Hip flexors 60s each Hamstrings 60s each |
| Tuesday | None — recovery day | Rest or light cardio | 5 min full-body stretch |
| Wednesday | Plyo: Med Ball Rotational Throws × 5 each side Strength: Machine Chest Press or Band Push-Up × 8–10 |
MMA / Grappling | Thoracic spine 60s Shoulders 60s each |
| Thursday | Plyo: Broad Jumps × 5 Strength: Lat Pulldown or Band Row × 8–10 |
MMA / Sparring | Adductors 60s each Glutes 60s each |
| Friday | None — recovery day | Rest or light cardio | 5 min full-body stretch |
| Saturday | Plyo: Clap Push-Ups × 6 Strength: Banded Hip Hinge or Machine RDL × 8–10 |
MMA / Mixed drilling | Calves 60s each Neck 60s each side |
| Sunday | Full rest | Full rest | 10 min deep stretch (optional) |
Note: machines and bands are preferred over heavy barbells in the add-on context. After explosive plyometrics, stabiliser muscles will be partially fatigued — a leg press or banded movement reduces injury risk compared to a loaded barbell squat. If you feel flat or sluggish during your main session, drop the add-on for that day. Skill work always comes first.
🔬 Unique Insight: What the Research & Community Actually Say

| Finding / Source | Protocol | Duration | Key Result |
|---|---|---|---|
| Schoenfeld et al. (2025 CUNY Study) | 1 set × 9 exercises, 2×/wk | 8 weeks | Trained lifters gained muscle and strength; failure group had a slight hypertrophy edge |
| Krieger (2010) Meta-Analysis | Single vs. multiple sets | Various | Single sets achieve ~85–90% of the gains from multiple sets |
| PubMed Review (Carpinelli & Otto) | Single vs. multiple sets | 4–25 weeks | No significant difference in strength or hypertrophy outcomes |
| Fisher Lab (PhD student research) | 1 set, 1×/wk | Multi-week | Even elite powerlifters got stronger with a single weekly set |
| Markovic & Mikulic (2010) Plyo Meta-Analysis | Plyometric training | Various | CMJ improved 4.7–8.7% across jump types |
| Micro vs. High-Dose Plyo (2025) | Microdose vs. high volume | 4 weeks | Both doses produced similar jump and reactive strength improvements |
| Volleyball Plyo Meta-Analysis (2020) | Plyometric jump training | 6–8 weeks | 6–11% VJH improvement; 1 vs 2 sessions/wk showed similar gains |
💬 What the Fitness Community Reports
Forum members and experienced lifters consistently echo several themes around single-set training:
- Beginners thrive: Nearly universal agreement that single-set protocols deliver excellent early gains regardless of method — the stimulus of any structured training is enough.
- Failure is draining: Multiple forum users report that daily training to true failure causes chronic fatigue, low energy, and in some cases injury. Stopping 1–2 reps short appears more sustainable long-term.
- Lockdown proof-of-concept: Several lifters maintained or built muscle during gym closures using just one high-rep set to failure daily (push/pull/legs split), noting that recovery was manageable at higher rep ranges (~20 reps) but not at heavy loads.
- The 6-month wall: Experienced members note that single-set gains tend to plateau after roughly 6 months, at which point additional volume or periodisation becomes necessary for continued progress.
- Simplicity wins adherence: The most-cited benefit is consistency — a 30-minute session twice a week is something people actually stick with, and adherence drives results more than any optimal programme abandoned after two weeks.
🔬 Unique Insight: The MED Across All Three Domains
Comparing the minimum effective dose for strength, power, and flexibility side by side
| Domain | MED Per Session | MED Per Week | Diminishing Returns After | Source |
|---|---|---|---|---|
| Strength (Resistance) | 1 set per exercise to near failure | 2 sessions (~60 min total) | ~6 months (for beginners/intermediates) | Schoenfeld 2025; Krieger 2010; Carpinelli & Otto 1998 |
| Power (Plyometrics) | 1–2 sets of 5–10 reps | 2–3 sessions (~45 min total) | Microdose ≈ high-dose for jump/reactive strength | Markovic 2010; Liu et al. 2025; Ramirez-Campillo 2018 |
| Flexibility (Static Stretching) | 30–60 sec hold; max ~3 min per muscle | ~8–10 min per muscle group | >3 min/session or >10 min/wk per muscle | Ingram et al. 2024 (189 studies); Bandy & Irion 1994 |
| MMA-Specific S&C | Low-volume, high-intensity compound work | 2–3 short sessions alongside skill work | High-volume circuits underperformed low-volume in fighters | Kostikiadis et al. 2018 (MMA athletes, 4 weeks) |
🥊 Why This Matters for MMA Fighters
A 2018 study on well-trained MMA athletes found that a 4-week low-volume, high-intensity S&C programme (3×/week) produced large improvements in squat, bench, and deadlift 1RM, jump power, sprint speed, and even VO2max — while a traditional high-volume circuit group saw no significant changes. The fighters who trained less volume, but with more intent, improved across the board.
This aligns perfectly with the single-set philosophy. As a fighter, your nervous system is already under enormous demand from grappling, striking, and sparring. Adding high-volume gym work on top creates a recipe for overtraining, blunted reactions, and increased injury risk. A single set of focused resistance work and a single set of explosive plyometrics — done before your skill session — gives you the stimulus you need without draining the tank.
As the saying in MMA S&C goes: “Lift to fight better, don’t fight to lift better.”
Conclusion
Single set resistance and plyometric training offer practical, time-efficient ways to build strength and power. Scientific evidence supports their effectiveness, especially for beginners and those with limited time. Following minimum effective dose principles helps you achieve meaningful results over 12 weeks without excessive volume.
The same MED principle now extends to flexibility: just 30–60 seconds per stretch, accumulating roughly 8–10 minutes per muscle per week, is enough to improve range of motion — no hour-long yoga sessions required.
For combat athletes, the add-on protocol offers a way to build strength and power without separate gym sessions or risking overtraining. Arrive early, do your single sets with intent, then train your sport. Just be mindful of CNS fatigue — favour machines and bands over heavy barbell work when bolting this onto a main session, and always prioritise skill training and recovery.
Using quality equipment like resistance bands, plyometric boxes, and medicine balls further improves safety and training quality.
Consistency and gradual progression are key. Start with manageable volumes, focus on technique, and track your progress to stay motivated and on track.
