With a torn bicep tendon, you can still exercise, but what’s safe depends on where the tear is, whether you had surgery, and how far along you are in healing. The wrong movement at the wrong time can make things significantly worse, so understanding the phases of recovery matters before you pick up any weight.
Proximal vs. Distal Tears Change Everything
The bicep tendon attaches at two points: near the shoulder (proximal) and near the elbow (distal). These are very different injuries with different exercise timelines.
A proximal tear, the more common type, often heals well without surgery. You lose roughly 30% of elbow flexion strength initially, but most people regain nearly full function over time. Surgery is typically reserved for younger, active people who can’t tolerate even mild weakness or who want to avoid the cosmetic “Popeye” deformity where the muscle bunches up.
A distal tear, near the elbow, is more serious. Without surgical repair, you can permanently lose 30% to 50% of your forearm rotation strength and about 20% of elbow flexion. Distal tears are almost always repaired surgically, and the rehab timeline is stricter. If you haven’t seen an orthopedic surgeon yet for a suspected distal tear, that should be your first step before thinking about exercise.
Weeks 0 to 4: Passive Movement Only
Whether you’re managing a proximal tear conservatively or recovering from surgery, the first month is about protecting the tendon while preventing stiffness. You’re not strengthening anything yet. The goal is restoring passive range of motion, meaning someone else (or your other hand) moves the injured arm through its range while the bicep stays completely relaxed.
Two key movements in this phase:
- Pendulum exercises (Codman’s): Lean forward, let your injured arm hang straight down, and gently swing it in small circles using your body’s momentum. Your arm muscles stay totally relaxed. This keeps the shoulder joint mobile without loading the bicep at all.
- Passive elbow flexion and extension: Use your good hand to gently bend and straighten the injured elbow. You can also passively rotate the forearm palm-up and palm-down. The key word is passive: the injured arm does zero work.
During this phase, avoid reaching behind your back, rotating your shoulder outward past about 40 degrees, or extending your arm behind your body. These positions stress the healing tendon.
Exercises You Can Do With the Rest of Your Body
Having a torn bicep tendon doesn’t mean you stop training entirely. You can keep a surprising amount of your fitness routine going if you’re smart about it.
Lower body work is generally fair game from the start. Squats, lunges, leg presses, leg curls, calf raises, and hip thrusts don’t involve the bicep. If you need to hold a barbell for squats, use a safety squat bar or switch to goblet squats held on the uninjured side. Avoid any grip-heavy lower body movement like heavy deadlifts or farmer’s carries, which load the bicep tendon significantly.
Core exercises that don’t require gripping or arm support work well too: crunches, leg raises, planks on your uninjured side, and seated rotational movements. Ab machines where you hook your arms behind pads rather than gripping handles can be useful.
For the uninjured arm, you can train it normally. Single-arm work won’t cause problems on the other side, and there’s actually some evidence that training one limb provides a small protective crossover effect for the opposite side.
Weeks 4 to 8: Light Active Movement
Once the tendon has had a month to heal (and your surgeon or physical therapist clears you), you begin active range of motion. This means the injured arm starts doing the work itself, but without resistance. You’re simply bending and straightening the elbow under its own power, rotating the forearm, and gently moving the shoulder through comfortable ranges.
Isometric holds often start in this window. These are contractions where the muscle fires but the joint doesn’t move. For example, you press your palm up against the underside of a table with about 25% to 50% effort and hold for 5 to 10 seconds. The elbow stays bent at a fixed angle. Isometrics are valuable because they begin reloading the tendon without the mechanical stress of movement.
You can also start working surrounding muscles more deliberately now. Tricep exercises that don’t stress the bicep, like overhead tricep extensions or pressdowns using a rope attachment, help maintain arm strength. Wrist curls and reverse wrist curls with very light weight keep the forearm muscles active. Shoulder work like lateral raises (light weight, controlled movement) is typically tolerable as long as it doesn’t provoke pain at the injury site.
Weeks 8 to 12: Progressive Strengthening
Strength training for the bicep itself usually begins around two to three months post-injury or post-surgery. You start with light resistance bands or very light dumbbells, performing standard curls with careful control. The focus is on building tolerance gradually, not testing your limits.
This is also when eccentric training becomes particularly useful. Eccentric loading means controlling the lowering phase of a curl slowly while using your good hand to help lift the weight back up. You lower a weight over 3 to 4 seconds with the injured arm, then assist it back to the top with both hands or the uninvolved arm. In a case study of a high-level wrestler rehabbing distal biceps tendinosis, the athlete started eccentric curls at a weight that was “uncomfortable but not disabling,” performing 3 sets of 7 reps daily in two positions: forearm supinated (palm up) and forearm neutral (thumb up). He increased the weight in 5-pound increments whenever the reps became pain-free, progressing from 30 pounds to 55 pounds over about four weeks.
Some discomfort during eccentric loading is expected and even considered part of the therapeutic process. But sharp pain, sudden weakness, or swelling means you’ve gone too far.
Months 3 to 6: Return to Full Training
Sport-specific and heavier lifting activities typically begin around the 12-week mark. In a documented case of a competitive strongman recovering from distal biceps repair, strength training started at roughly three months, but full return to heavy pulling and implements didn’t happen until six months post-surgery, when isokinetic strength testing showed symmetrical results between both arms.
Pull-ups are one of the last exercises to come back. That same athlete started with band-assisted pull-ups at the six-month mark and progressed from there. This makes sense: a pull-up places enormous load on the bicep tendon, combining elbow flexion with full body weight. Rushing back to pull-ups is one of the most common ways people re-injure the tendon.
The general progression for returning to the gym looks like this: resistance bands, then light dumbbells, then cables, then barbells, then bodyweight pulling movements. Each stage should feel controlled and relatively comfortable before you move to the next.
Movements to Avoid During Recovery
Certain exercises are risky throughout most of the recovery process and should only return once you’re fully cleared:
- Heavy pulling movements: Deadlifts, barbell rows, and pull-ups all place high demand on the bicep tendon. These are typically the last to return.
- Supinated gripping under load: Holding heavy weight with your palms facing up (like an underhand barbell curl or chin-up grip) maximally loads the bicep tendon.
- Quick, explosive arm movements: Kettlebell swings, cleans, snatches, and any exercise involving sudden deceleration through the elbow put the healing tendon at risk.
- Heavy carrying: Farmer’s walks, suitcase carries, and even carrying heavy grocery bags create sustained tension through the bicep.
The most important principle across all phases is that pain is your guide but not your enemy. Mild discomfort during rehab exercises is normal. Sharp or sudden pain, especially at the site of the tear, means you need to back off. Progressing too quickly is far more common than progressing too slowly, and a re-tear sets you back to square one with a more complicated repair.
