Viking Strength Training: What Norse Warriors Teach About Functional Fitness
What Viking daily physical life actually involved, and how rowing, loaded carries, and functional strength training map onto real exercise science.
Viking strength training, as the Norse actually lived it, was not a program. No Viking training text, schedule or method survives. What the record does show is a seafaring culture of 60-oar warships and a saga tradition that prized stone lifts, wrestling, ball games and feats of agility. Almost everything sold as a “Viking workout” is a modern invention dressed in Norse language.
Myth or fact? We graded “Vikings were giants” an F (false) in our Evidence Index, where 120 popular health claims are graded A to F against the research.
Below: what the ships, skeletons and sagas really tell us, where the evidence runs out, what modern research says about each activity, and a simple twice-a-week Viking workout plan built from the parts that hold up.
How Did Vikings Train? What the Documented Record Actually Shows
Norse physical life is reconstructed from three kinds of evidence, and they carry very different weight.
The ships and the laws. The Viking Ship Museum in Roskilde, Denmark, rebuilt a longship known as Skuldelev 2: a 98-foot (30-meter) sea-going warship with 60 oars and room for a crew of 80. It also carried a square sail of about 1,200 square feet (112 square meters), so oars shared the work with the wind (1). Norwegian law written down in the 1100s and 1200s, just after the Viking Age, describes the crews: ordinary crewmen were young men picked by the steersman, kept fixed watches and often had to supply the ship’s weapons (2). That is a picture of organized, physically demanding crew work, not of a gym.
The skeletons. A study of skeletons from northern Europe estimated that men in the early Middle Ages, the period that overlaps the Viking Age, averaged about 5 feet 8 inches (173.4 cm). Heights then fell to roughly 5 feet 6 inches (167 cm) by the 1600s and 1700s and did not recover until the early twentieth century (3). So the “Viking physique” was tall for its time, not gigantic. The study’s author suggests the later decline is plausibly linked to a colder climate, growing inequality, crowded towns and the spread of disease, which tells you that height tracked nutrition and health, not training. The sample was also modest, so treat the exact figure as an estimate.
The sagas. These are the richest descriptions of strength and the weakest evidence, for reasons covered next.
The Sagas as Evidence: Stone Lifts, Wrestling and Ball Games
The Old Norse sagas were written centuries after the events they describe, largely by Icelandic authors working from oral tradition and earlier, now-lost manuscripts (4). They are literature with a point of view, not field notes.
Read that way, they are still revealing about what Norse audiences admired:
- Agility and all-round skill. Heimskringla, the history of Norway’s kings compiled by the Icelander Snorri Sturluson in the 1200s, says King Olaf Tryggvason climbed the Smalsarhorn peak to plant his shield on top, could run across the oars outside his ship while his men were rowing, juggled three daggers, and could throw two spears at once (5). Note the framing: Olaf is called more skilled than any Norwegian “whose memory is preserved to us in sagas”, and the text adds that many stories were written down about it.
- Stone lifting. In Grettir’s Saga, written down in Iceland in the early 1300s, the young Grettir lifts a stone in the grass that the saga says was “still known as Grettishaf”, and people came to stare at it (6).
- Games and wrestling. The same saga describes young men from several districts meeting in autumn for ball games on the ice of a lake, and wrestling bouts at a regional assembly, weakest pairs first and strongest last (6).
Notice what these passages are: feats, contests and play, told to impress. None of them describes sets, reps or a weekly routine. You will also see later Icelandic lifting stones, such as the Húsafell stone, offered online as proof of Viking training. We could not find a primary source that dates any of them to the Viking Age, so we treat them as later folk tradition, not evidence.
Documented Record Versus Legend
| Common claim | What the evidence supports | Verdict |
|---|---|---|
| Vikings followed a structured strength program | No training text, schedule or method survives | No evidence |
| They were enormous | Early medieval northern European men averaged about 5 ft 8 in (173 cm) | Tall for the era, not giants |
| Rowing built their upper bodies | A rebuilt warship has 60 oars but also a big sail; we found no study measuring the effect | Plausible, unproven |
| Loaded carrying was central | No direct record; inferred from a pre-industrial working life | Plausible, unproven |
| They lifted stones for sport | Sagas describe it, written centuries later | Literary tradition |
| Berserker rage was a training state | Scholars debate a ritual or dissociative state | No evidence |
What Modern Research Says About Each of Those Activities
The history cannot tell you whether this kind of work is good for you. Modern studies can, one component at a time.
Rowing. In a small randomized trial, post-menopausal women in their mid-60s rowed on a machine for 30 minutes, three times a week, at 60% to 80% of peak heart rate. After ten weeks their peak oxygen uptake, cardiac output and heart-rate recovery had all improved (7). Unlike walking or cycling, rowing also trains a pulling movement, which makes it a natural fit for a Norse-inspired plan.
Loaded carries. In an electromyography study of college-aged adults, walking with a heavy dumbbell in each hand (a farmer’s carry) switched on the trunk muscles more than simply holding the same weights still, and carrying a single dumbbell on one side (a suitcase carry) added extra one-sided work (8). Spine biomechanist Stuart McGill’s analysis of strongman events reached a similar conclusion: carrying challenges different abilities than lifting, so carries are a useful addition to a lifting program. The same analysis found that the heaviest carry, a yoke across the shoulders, put the highest load on the spine of any event tested, so heavier is not automatically better (9). For carrying weight on your back over distance, see what the research shows on rucking.
Stone and odd-object lifting. Here the honest answer is mixed. McGill’s team found that lifting an atlas stone makes a protective neutral spine impossible, loading the back in a weakened, rounded position (9). On the other hand, a 7-week randomized trial in 30 rugby players, training twice a week, found strongman implement training about as effective as traditional gym training for strength, power and speed, with bigger gains in bent-over row strength and smaller gains in squat and deadlift strength (10). Odd objects work; heavy stones are a specialist skill, not a starting point.
Grip. Every one of these tasks runs through the hands. In the PURE study of nearly 140,000 adults in 17 countries, each 11 lb (5 kg) lower grip strength was linked to a 16% higher risk of death from any cause over about four years (11). That is an association, not proof that training grip extends life, but it is why grip matters. More in grip strength and longevity.
Long, steady work. If Norse strength came from work, it came mostly from long stretches of moderate effort rather than short maximal lifts. That is closer to aerobic base training than to a bodybuilding block, and it lines up with the World Health Organization’s advice: 150 to 300 minutes of moderate activity a week, plus muscle-strengthening work for all major muscle groups on two or more days (12). Our guide to zone 2 cardio for longevity covers how to do the steady part well.
Where the Evidence Runs Out
Four things are routinely claimed and cannot be supported.
- Any specific Viking set-and-rep scheme is invented. There is no recorded Norse strength method to reconstruct.
- Popular claims of a distinctive Viking upper body are unsupported. We could not find a skeletal study measuring it, so we have removed that claim from this page. Bones mostly record the consequences of a hard life, which is not the same as a deliberate training effect.
- Berserkers were not a training method. A 2021 paper in the journal History of Psychiatry concluded that berserker frenzy is best explained as a temporary dissociative state shared by small warrior bands steeped in religious ideology, and that drugs alone cannot account for it (13).
- The “Viking” label is often branding. If you searched for a Viking workout, you may have met Viking Warrior Conditioning, a 2011 kettlebell conditioning book by former Master RKC instructor Kenneth Jay. Its protocols grew out of oxygen-uptake and lactate testing of kettlebell snatch training, not Norse sources (14).
What Is Actually Transferable
Strip the branding and a defensible pattern remains: carry heavy things, pull more, train your grip, and build a base of long, moderate effort. That is a reasonable template, not because Vikings did it, but because the modern evidence for each component holds up on its own.
We have looked at other historical systems the same way, separating what is documented from what is claimed: the Soviet kettlebell method, Roman legionary training, the Spartan agoge and samurai training. For a steppe culture that trained in the saddle rather than at the oar, our look at Mongol warrior training covers mounted archery from childhood and what grip research adds. The overview of ancient training methods science says actually work pulls them together.
Viking Workout Plan: Train the Pattern Twice a Week
This plan is built from the elements the evidence supports, not from anything a Norse source prescribes. Do Session A and Session B on two non-consecutive days, plus one long, easy outing in the week. Warm up for five minutes first with easy rowing or brisk walking and a few hip hinges.
| Exercise | Dose | When | Why it is here |
|---|---|---|---|
| Farmer’s carry | 4 x 130 ft (40 m) | A and B | Trunk and grip under load (8, 9) |
| Suitcase carry | 2 x 100 ft (30 m) each side | A | One-sided trunk control (8) |
| Rowing machine or band row | 15–20 min, conversational | A and B | Aerobic base plus pulling (7) |
| One-arm dumbbell or inverted row | 3 x 8–12 | B | Strength for the back (12) |
| Sandbag lift to shoulder, light | 3 x 3–5 | B, optional | Odd-object skill, kept light (9, 10) |
| Dead hang | 2 x as long as you can | A and B | Simple grip tracker (11) |
| Long walk, ruck or row | 30–45 min, easy | Once a week | Steady work toward the WHO target (12) |
Choosing loads. For carries, start with a weight you could carry twice as far, and rest until your grip recovers. Add load before you add distance. For the hang, track the seconds week to week; it is the simplest progress marker you have. See dead hang benefits for what hanging does and does not do.
If you only have twenty minutes, do the farmer’s carries, a short row and the hang.
Is a Viking Workout Safe After 40?
For most healthy adults, yes, because the plan uses moderate loads and familiar movements. A few cautions:
- Back pain or a past disc problem. Keep carries moderate and skip odd-object lifts, which can force a rounded back (9).
- Heart disease or high blood pressure. Get medical clearance before heavy carries and hard rowing.
- Grip or elbow pain. Use lighter weights for longer distances, or straps for some sets, and build the hang gradually.
Stop and see a doctor or physical therapist if pain travels down a leg or comes with numbness or weakness, or if you get chest pain, dizziness or unusual breathlessness during a session.

Frequently asked questions
Did Vikings actually train, or did they just get strong from daily life?
No Viking training text, schedule or method survives. The record shows a seafaring culture with 60-oar warships, and sagas written centuries later describe stone lifts, wrestling, ball games and feats of agility. Most of their strength almost certainly came from work and contests rather than a structured program.
What is a good Viking workout plan?
Two sessions a week built on farmer's carries, suitcase carries, rowing, one-arm or inverted rows and dead hangs, plus one long, easy walk, ruck or row. That matches the World Health Organization advice of muscle-strengthening work on two or more days a week alongside 150 to 300 minutes of moderate activity.
What single exercise best replicates Viking-style training?
The loaded carry is the closest match. In one study, walking with a heavy weight in each hand activated the trunk muscles more than holding the same weights still, and strongman research suggests carries train abilities that ordinary lifts miss, while building grip at the same time.
How tall and strong were the Vikings?
A study of skeletons from northern Europe estimated that early medieval men averaged about 5 ft 8 in (173 cm), tall for the era and not matched again until the early twentieth century. They were well built for their time, not giants, and no study has measured Viking strength directly.
How is Viking training different from Roman or Spartan training?
Roman and Spartan writers described organized training systems for soldiers and boys. For the Vikings no comparable training text exists, so their strength has to be inferred from ships, skeletons and sagas. All three point toward loaded, full-body work, but the Norse evidence is the thinnest.
Is rowing really as good as people say for overall fitness?
It is a strong option. In a small trial, women in their 60s who rowed for 30 minutes three times a week for ten weeks improved their peak oxygen uptake and heart-rate recovery. Rowing also trains a pulling movement that walking and cycling do not.
Were berserkers real, and did they train differently?
Berserkers appear in both written and archaeological sources, but there is no evidence of a berserker training method. A 2021 paper in History of Psychiatry concluded their frenzy is best explained as a temporary dissociative state shared by small warrior bands, not something drugs alone can explain.
