I Have Lower Back Pain and Lifting Weights Makes My Back Feel Weak

Your lower back may feel weak or unable to handle the weight while lifting because repeated effort can fatigue an already strained or painful back.

When lifting weights makes your back feel weak, you may notice that the first few repetitions are manageable but your lower back starts feeling tired as the workout continues. The muscles around your lower spine have to keep working while you lift, bend, and return to an upright position, so an already painful or strained back can fatigue more quickly than usual.

That weakness can also change how comfortable the movement feels. Instead of feeling solid through the lift, you may hesitate, slow down, or feel as though your lower back does not want to support the movement normally.

The First Few Reps Feel Hard On Your Lower Back

A painful lower back can fatigue quickly when it has to support repeated lifting movements.

Your lower back muscles help keep your trunk supported while you pick up and move a weight. If those muscles are already sore or strained, lifting can make them tire sooner, so you may feel weakness or a lack of confidence in your back even when the weight itself does not seem unusually heavy.

Your Back Feels Weaker As The Workout Goes On

Repeated lifting can turn a manageable back problem into a noticeably tired or weak feeling.

As repetitions build up, the muscles around your lower back can become fatigued and less able to maintain the same level of support. You may notice the weakness most when you are several sets into your workout, when you straighten up after a lift, or when you try to repeat a movement that felt easier earlier.

Why Your Lower Back Feels Weak During Lifting

Your lower back 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 lower back feeling stiff, tight, weak, or painful during everyday movement and activity.

What Can Help Your Lower Back Feel Better

Your lower back 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.
