Why Can't I Lift My Arm After Lifting Weights?

Your arm won't lift after weightlifting because the muscles, tendons, or other structures that help raise your shoulder have been strained or injured during the workout.

You may notice the problem as soon as your workout ends or when you wake up the next morning. Reaching into a cabinet, washing your hair, or lifting your arm out to the side suddenly feels weak, painful, or like your shoulder simply refuses to cooperate. Even though your elbow and hand move normally, the shoulder feels like it hits a wall.

This usually happens because one or more of the muscles that lift and stabilize your shoulder became overstressed during heavy lifting. The more irritated those structures become, the harder it is for your shoulder to move comfortably through its normal range of motion.

Raising Your Arm Feels Like It Suddenly Stops

You may feel sharp pain or weakness halfway through lifting your arm.

Many shoulder injuries become most noticeable between waist level and shoulder height. As you try to raise your arm, the rotator cuff works harder, and an injured tendon can make the movement feel painful, weak, or restricted. You may instinctively stop because it feels like something catches inside the shoulder.

Everyday Movements Become Surprisingly Difficult

You notice the shoulder more during simple daily activities than during the workout itself.

Putting on a shirt, reaching into the back seat, or lifting a light object overhead may suddenly become uncomfortable. If the shoulder remains weak, painful, or difficult to move for more than a couple of days, or you cannot actively raise your arm at all, a more significant injury such as a rotator cuff tear should be evaluated by a healthcare professional.

Why Your Arm Could Be Taking Longer To Heal

Your arm has a hard time healing when blood flow and circulation are limited.

Tendons, ligaments, and other soft tissues naturally receive less blood supply than many other parts of the body. Because of this, they often take longer to heal after repeated stress or injury, leaving you more vulnerable to lingering pain and a cycle of reinjury.

When circulation through the area remains limited, injured tissues have a harder time receiving the vital oxygen and nutrients they need to repair and heal. This can leave your arm feeling stiff, tight, weak, or painful during everyday movement and activity.

What Can Help Your Arm Feel Better

Your arm starts feeling better when blood flow and circulation improve.

Chinese herbs have been used for centuries to promote healthy blood flow and circulation. Their medicinal properties help break up stagnant blood and fluids that remain trapped around injured tissues, interfering with circulation. As circulation improves, blood flows more freely through the area, allowing those tissues to receive the oxygen and nutrients they need to heal properly.

Topical herbal remedies made with these Chinese herbs can help relieve pain while improving blood flow and circulation to injured tissues. The right product depends on your symptoms and whether you're in the acute or chronic stage of recovery.

If you have pain, swelling, inflammation, or bruising, Acute Sinew Liniment helps relieve these symptoms by increasing circulation and dispersing stagnant blood and fluids around the injured area to speed recovery. During the acute stage of healing, getting circulation moving early allows injured tissues to receive the fresh blood, oxygen, and nutrients they need to repair and heal.

If your injured area is especially swollen, red, or warm to the touch after a recent injury or flare-up, Sinew Herbal Ice is also used to reduce swelling and inflammation while restoring normal circulation so you can quickly regain range of motion. While traditional ice is commonly used to reduce swelling, Sinew Herbal Ice acts as an ice alternative to reduce swelling and inflammation while also dispersing accumulated blood and fluids to speed the healing process.

If you no longer have swelling or inflammation, but still have pain, stiffness, weakness, or sensitivity in cold and damp weather, Chronic Sinew Liniment helps relieve these symptoms by strongly stimulating circulation and increasing blood supply to injured tendons and ligaments to promote their healing. This is especially important because tendons and ligaments naturally receive less blood supply, which is why chronic injuries can take longer to heal.

If you have residual pain and stiffness, or the area becomes more painful in cold weather, Sinew Injury Poultice is also used to significantly stimulate circulation to injured tendons and ligaments to further promote their healing. By strongly increasing circulation, it counteracts the reduced blood flow caused by cold weather that commonly aggravates chronic tendon and ligament injuries.

If you exercise, play sports, or do other strenuous activities, Sinew Sports Massage Oil warms and stimulates muscles for exertion and relieves muscle tightness and soreness after activity. Warming and preparing your muscles before activity can improve flexibility, enhance performance, and reduce the risk of injury.

Frequently Asked Questions

You may also find these commonly asked questions helpful.

Why can't I lift my arm after lifting weights?

The most common reason is a strained rotator cuff, irritated shoulder tendon, or another shoulder injury that makes lifting your arm painful or weak.

Should I stop working out if I can't raise my arm?

Yes. Continuing to train through significant pain or weakness can make the injury worse.

Could I have torn my rotator cuff?

Possibly. If you cannot actively lift your arm or have marked weakness after a heavy lift, you should be evaluated promptly.

Is shoulder soreness the same as not being able to lift my arm?

No. Normal muscle soreness may feel achy, but it should not prevent you from lifting your arm through its normal range of motion.

When should I see a healthcare professional?

Seek medical evaluation if you have severe pain, obvious weakness, swelling, deformity, or your symptoms are not improving over the next several days.
