What is a biceps muscle strain?
Biceps brachii anatomy
Biceps brachii is the muscle at the front of the arm, between the shoulder and the elbow. It’s made up of two heads (long and short) that join to form a single muscle body. Its main role is to flex the elbow and supinate the forearm (turn the palm upward). It’s a muscle heavily used in pulling and arm-flexion movements, whether in weight training, climbing or combat sports.
Why does this muscle get injured?
A biceps muscle strain most often occurs during a sudden eccentric contraction, meaning when the muscle is stretched while trying to contract, such as during the lowering phase of a too-heavy curl, a climbing pull on a hold that slips, or a forced flexion effort in judo or wrestling. Insufficient warm-up, too rapid an increase in load, or significant muscle fatigue are factors that increase the risk of injury.
Symptoms and diagnosis of a biceps muscle strain
Pain and typical signs
The pain appears suddenly during the effort, sometimes accompanied by a snapping sensation or a feeling of tearing at the front of the arm. Noticeable weakness when flexing the elbow or supinating the forearm often follows the initial pain. Bruising can appear in the following hours or days, a sign of a more significant injury, and a visible deformity in the muscle contour points to a more severe rupture of the muscle body or tendon.
Differential diagnosis
Other arm pain can sometimes be mistaken for a biceps muscle strain:
- Long head of biceps tendinopathy, a shoulder pain that develops gradually, with no clear traumatic mechanism
- Distal biceps tendinopathy, more centred on the elbow and linked to repeated overuse rather than a single sudden effort
Causes and risk factors
A biceps muscle strain most often occurs during an explosive movement or an eccentric contraction on a muscle that isn’t sufficiently prepared.
Risk factors
- Insufficient warm-up before a maximal pulling or flexion effort
- Too rapid an increase in training loads (curls, rows)
- Significant muscle fatigue late in a session or a bout
- A strength imbalance between the biceps and the antagonist muscles
- A previous biceps injury, a risk factor for recurrence
Which sports contribute to biceps muscle strains?
Any sport that heavily demands elbow flexion or pulling, particularly eccentrically, exposes the biceps to this type of injury:
- Weight training, particularly biceps curls or poorly controlled bench press
- Climbing and gripping sports
- Combat sports, particularly boxing
- CrossFit and heavy pulling movements
- Throwing and racquet sports, such as tennis
- Rugby, during tackling and ground-fighting phases
Treating a biceps muscle strain in rehab with a sports physio
The goal of treatment is to allow the muscle to heal under good conditions, then progressively restore its strength and elasticity to prevent any recurrence, which is often more serious than the initial injury.
- 1Protection and relative rest of the area
- 2Gentle elbow and shoulder mobility
- 3Light isometric contractions
- 4Progressive concentric strengthening
- 5Eccentric strengthening of the biceps
- 6Full arm chain work
- 7Reintroducing sport-specific movements
- 8Strengthening under sport-specific load
- 9Progressive return to your sport
- 10Return to competition
“A poorly managed muscle injury is the best way to get hurt twice in the same place.”
Progressive strengthening, the cornerstone of treatment
Strengthening the biceps must be introduced progressively, starting with pain-free isometric contractions before moving to concentric then eccentric work. Eccentric strengthening is particularly important because it’s precisely this type of contraction that’s behind most muscle strains: re-accustoming the muscle to this effort in a controlled way makes it more resilient going forward.
In brief
- Isometric then progressive concentric strengthening
- Eccentric strengthening to prevent recurrence
- Associated elbow and shoulder mobility
- Gradual return: mobility, then load, then sport

Should you rest or keep playing sport?
Prolonged total rest isn’t recommended: it causes loss of muscle mass and strength, which increases the risk of recurrence when you return. It’s better to temporarily adapt your activity, avoiding movements that clearly reproduce the pain, while quickly starting active, progressive rehab as soon as the acute pain eases.
Think you might have a different arm injury?
Take your free test in 3 minutes flat.
When should you see a specialist for a biceps muscle strain?
If you feel sudden pain accompanied by a “pop”, visible deformity of the muscle, or an inability to flex the elbow, prompt medical attention is needed to rule out a complete rupture, which can sometimes require surgery. Pain that persists beyond two to three weeks despite relative rest also warrants a specialist opinion.
Recovery time for a biceps muscle strain
A simple strain (grade 1) can resolve in one to two weeks, while a partial tear (grade 2) generally requires four to six weeks of progressive rehab before a full return to sport. A complete rupture (grade 3), which is rarer, can take several months to recover from and may sometimes require a surgical opinion.
Preventing re-injury
A muscle strain that’s rushed back into action too soon carries a high risk of recurrence, often more severe than the original injury. Several measures can help reduce this risk:
- Carry eccentric strengthening all the way through before fully returning to activity
- Keep up specific biceps warm-up before every heavy pulling or flexion session
- Progressively adapt your training load, without sudden jumps
- Don’t return to sport or competition until strength and mobility criteria are met
The HOPP care programmes to treat your biceps muscle strain and get back to sport
To heal durably and prevent recurrence, a biceps muscle strain requires a progressive, well-dosed return to loading. HOPP offers you a precise exercise programme, allowing you to get back to your activities as quickly as possible. By combining stretching, mobility, concentric and eccentric strengthening, and training management, HOPP supports you all the way back to the field for an optimal, confident return.
The programme runs from 3 to 9 weeks depending on the injury and ends with a reconditioning phase allowing a return to competition in the best possible conditions. Each programme is designed by the HOPP team, made up of two sports physiotherapists who are experts in assessing and treating athletes. You’ll also find theoretical content throughout your progression, so you master every aspect of your recovery and can adjust your treatment independently. If needed, our team of physiotherapists is on hand to support you.

A programme that adapts to you every day
Every day, how you feel (RPE) is factored in to automatically adjust the rest of your programme: more load if all is well, a bit less if your arm is complaining. This daily personalisation is what makes the difference compared to a fixed, paper-based programme.

F.A.Q
How long does it take to recover from a biceps muscle strain?
It depends on the grade of the injury: a simple strain (grade 1) can resolve in one to two weeks, while a partial tear (grade 2) generally requires four to six weeks of progressive rehab before a full return to sport.
Can I keep training with a biceps strain?
It’s better to avoid movements that directly stress the biceps (pulling, curls, flexion against resistance) during the acute phase, but you can generally maintain cardio activity or work other muscle groups that don’t involve it.
How can I tell if it’s a tear and not just muscle soreness?
Muscle soreness generally appears 24 to 48 hours after exertion and fades gradually. A muscle strain causes more sudden pain, often felt during the effort itself, sometimes accompanied by bruising or a clear loss of strength.
Does the HOPP programme replace a medical consultation?
No. HOPP is a support and rehab tool designed by sports physiotherapists, but it doesn’t replace a doctor’s opinion. If in doubt, if there’s visible deformity, or if the pain persists, see a health professional.
Is the programme suited to all sporting levels?
Yes. Every programme is personalised to your sport, your level and how you feel each day, whether you’re a recreational athlete or preparing for competition.
Why does this injury come back so often?
The biceps is particularly prone to recurrence if eccentric strengthening isn’t carried through to completion before a full return to sport, which is why progressive reconditioning matters so much.
How can I tell a biceps muscle strain apart from long head of biceps tendinopathy?
A muscle strain happens suddenly, often during a specific effort, sometimes with a clear snapping sensation. Long head of biceps tendinopathy, by contrast, builds up gradually, with shoulder pain that worsens with use rather than a single traumatic episode.
