7 Most Common Weight Lifting Injuries (& How To Prevent Them)

We have enough reasons to not workout already, such as being tired or too busy with work or social engagements. But let’s not let this one become one of them: injury. Injuries can sideline the most well intentioned of us, and it’s not just bad luck that determines who gets hurt. Most of the time, it’s how we perform our exercises that contributes to these common injuries.

In my physical therapy practice, I often tell my patients and clients that we are all “natural cheaters”, meaning that we look for the easy way out or the easier way to do something. Sometimes this is ok, but most of the time we end up compensating. Many of these compensations can lead to excessive stress to specific body parts, leading to some very common injuries.

Here’s a brief intro to 7 of the more common injuries that can happen in the weight room, with tips to prevent them.

1. Disc Herniation (& Degenerative Disc Disease)

Disc herniations are often caused by poor lifting mechanics. When a patient tells me that he got hurt picking something up, this is one of the first things on my diagnostic list. Possible symptoms of a disc herniation can include localized back pain as well as numbness or tingling that travels down into the legs.

Another possibility is degenerative disc disease, which is a common term that doctors use to describe “excessive wear and tear on the spine”.

Both disc herniations and degenerative disc disease can be exacerbated by chronic poor posture, especially when lifting and exercising.

By placing your spine in the correct position, you’ll experience the least amount of stress to your discs and spine, and your core muscles will be able to engage more effectively.

Prevention Tips: If you stand up straight with your back against a wall, you should have a small natural curve at your low back. Keep this curve! This position is often called a “neutral spine” and should be maintained during all strengthening exercises. When lifting, focus on hinging at the hips and engaging your core to maintain a strong, neutral spine. Also, be wary of exercises like the Russian twist which puts a lot of stress on your discs.

2. IT Band Syndrome

This injury is very common for runners, especially if your form is suboptimal. The IT Band is a thick fibrous ligament on the side of your thigh that goes down to the outside of your knee. An injury here can cause pain anywhere from your outside hip bone down to your knee.

Prevention Tips: To help decrease stress and injury to the IT Band, make sure to keep your knees aligned with your toes and watch that your hips remain neutral (don’t let your pelvis drop to the opposite side) when you run or do single leg exercises.
Perform exercises to strengthen your glutes, which can help take stress away from the IT band by helping you strengthen and stabilize your hip and knee joints.

Best Exercise: The single leg hip hinge.

Additionally, you can roll out your IT Band on a foam roller, get a deep tissue massage, or get cup therapy (which is my favorite way of loosening up) to temporarily decrease some symptoms of IT Band Syndrome.

3. Achilles Tendonitis

Achilles tendonitis is another common injury for runners and is indicated by pain in the back part of the heel up to the Achilles tendon. These symptoms can linger and are often exacerbated by running, especially uphill or on sand.

Tendon problems frequently take a long time to heal. If you have Achilles tendonitis, the first step is to rest to decrease the inflammation, allowing the tendon to calm down. Then, gradually build up the strength in the calf muscle by doing heel raises.

Prevention Tips: Stretch your ankles and calves regularly, especially before running or doing leg exercises similar to the squat.

Best Warm-Up Exercise: Jump rope! This exercise will help strengthen the calves and keep you quick on your feet.

4. SLAP Tear

Most people have heard of rotator cuff injuries, but another part of the shoulder that commonly gets injured in athletes is the labrum. A SLAP tear (which stands for Superior Labrum Anterior and Posterior) can occur from both acute trauma and repetitive stress from motions like throwing or overhead lifting.

Be careful of workouts and exercises that repetitively stress your arms overhead or when fully rotated. If you can’t raise your arm without pain, feel that one or both shoulders are weak, or experience popping/catching in certain movements, visit a health practitioner to get a more complete diagnosis. Some labral tears can heal over time, but some require more aggressive treatments like rehab or surgery.

Prevention Tips: When people think about exercising the shoulder, they don’t usually think about the entire shoulder girdle. This includes the shoulder blade which absolutely needs to move to help support the shoulder.

Make sure to warm up your upper back before working out, and only exercise through a range-of-motion in which you can move your arm without pain. Always focus on keeping the optimal shoulder position when doing any upper body exercise: shoulders down and away from the ears!

Also, avoid strengthening movements where your arms are placed behind you, and avoid painful movements with your arms overhead.

Best Exercises: Incline dumbbell presses, reverse flies.

5. Tennis Elbow (Lateral Elbow Tendonitis)

This overuse injury is often caused by over-gripping, and can tend to linger like other tendon problems. Symptoms can include an ache on the outside of your elbow, and when you straighten your arm and pull your palm towards you, you’ll feel a stretch along the outside of the forearm muscle. Similar to Achilles problems, you’ll need to rest at first to calm down the inflammation before gradually strengthening your gripping muscles. You can alleviate some of the symptoms by regularly massaging and stretching the muscles, which can help increase blood flow. As the symptoms calm down, you can gradually increase the workload again with wrist exercises. Make sure that you don’t push through pain, which may exacerbate your symptoms and make things worse.

Prevention Tips: Start your workouts with heavy gripping exercises such as farmer’s carries. This will warm up your entire body while building your grip strength. Also, incorporating exercises like crawling and pushups can help to maintain wrist flexibility, which will help keep the muscles in your forearm flexible.

6. Hamstring Pulls & Tears

As soon as it happens, you’ll know it – a sharp, shooting pain in the back of the thigh. This injury is often caused by explosive activities like sprinting or jumping, which put a high demand on the hamstring muscles. Some hamstring tears require a full year or two to completely recover from. And unfortunately, re-tears are very common.

Prevention Tips: Before your sprint or plyometric workout, be sure to do a thorough warm-up, including easier sets of your exercises, and accelerations if you’re sprinting.
Also, make sure you maintain optimal flexibility in your hamstrings by not only stretching them, but strengthening them with exercises like the deadlift. Strengthen the glutes as well, as they significantly help to support the hamstrings when you perform sprints and jumps.

7. Patellar Tendonitis (& Knee Pain)

The patella, or kneecap, is often a source of pain for athletes of every sport.

Patellar tendonitis is a common injury characterized by pain at the patellar tendon, which is just below the kneecap. If you’re experiencing this, you definitely want to rest the knee and avoid stressing it while it’s inflamed. When the inflammation has decreased, focus on gradually building up the strength of your legs without flaring it up again. Visit a therapist who can show you how to progressively rebuild the load on the quads and the patellar tendon with eccentric exercises.

On the other hand, if your pain is located at the front of the knee, one of the first things I’ll look at is how you squat.

Most trainers focus on keeping the knees behind the toes during a squat. While this adjustment can decrease some stress to the knee, it’s much more important that the knees are in the correct alignment with the hips and ankles (when looking at the leg from the front). Ideally, the middle of your knee should track over your 2nd toe. Practicing proper form will minimize other stresses to the knee that occur when your knee caves inwards.

Prevention Tips: Keep the middle of the knee inline with the 2nd toe during every leg exercise. Whether you’re doing squats, lunges, step-ups, etc , watch where your knees track and make immediate adjustments! This will help decrease any lateral stresses to the knee, which can exacerbate knee problems.

Targeting your glutes during your workout is another great way to help decrease stress to the knee. Strengthening and engaging your hip muscles can help ensure proper knee alignment, thereby helping take the load off your knees.

By incorporating some key exercises into your workout and focusing on proper form, you can build a more injury-resistant body. Starting each workout with a thorough warm-up, correcting your muscular imbalances, and including flexibility training goes a long way. Train smart and stay injury free.

    Thanks for the article, Kenny. I've experienced every one of these injuries unfortunately, but I hope this article will help people become more mindful of injury prevention. I remember as a college athlete the #1 reason why we lifted weights was to prevent injury while playing sports, then secondly to improve performance. It's unfortunate there are so many injuries while people are exercising. It is becoming normal for people to injure themselves while lifting weights, but it shouldn't be that way.

  • David says:

    Great article!
    I have a few questions that i would like to ask.
    -First, do you reccomend wearing knee and elbow sleeves during lower and upper workouts perspectively?And if yes, then how tight those should be; approximately.I say that because if they are really tight they change the dynamics of the joint (they act like coils).
    -Is it OK for the lower back to feel sore like any other muscle group?I wake up with a sore low back after doing a barbell bent-over row the day before.I think i might exaggerated a bit on the "slight arch" part.After a few hours though, on the same day, it was gone.
    -Finally, my dominant side is the right(hand and foot) and i guess that's the reason why from toes to head(literally) my right side is a bit tighter, generally, than my left(i.e., tighter right hip vs. loosier left hip).The problem is, no matter how hard i work on this imbalance i can't seem to even it out.That said, my form in exercises like the front squat(i prefer the front squat over the back squat) is pretty darn good.It's just that, an imbalance, which i think doesn't affect my form.The question is, is there a problem with that?
    Sorry for the long post and as long time reader of BuiltLean i would like to welcome you to the team!

    • Kenny says:

      Generally, knee and elbow sleeves aren't so helpful where I would recommend them to everyone. That being, said, they do provide some benefit, especially with proprioception (your bodies ability to feel itself and its position)

      Low back soreness: consider this to be a yellow flag. These muscles can get sore just like any other part, but you want to make sure that you weren't stressing other parts of your back. You're much safer if the back is in "neutral", otherwise you are putting too much stress to the back.

      Imbalances between sides: this is normal. As long as it doesn't impair your form. Train the weaker side more for long term balance!

    • Marc Perry, CSCS, CPT says:

      All great question, David. I'll let Kenny know you commented and see if he can answer them soon

      • David says:

        Thanks a lot, Marc!
        Have a nice day.

  • Wendy says:

    Smashing article, very helpful.
    I have had problems with both knees and elbows. My knee pain I discovered stemmed from tight quads, due to overworking them. Rest and a foam roller helped. The pain in the elbows for me was purely from asking too much of the forearm muscles, causing them to tighten also. I'm currently working on my grip strength and the flexibility of my wrist joints.

  • Gareth Jones says:

    Great article Kenny, I really appreciate the prevention tips you've included as well.

    I've been quite fortunate not to injure myself too often in the gym but when I do it's almost always down to a breakdown in form.

  • Hiwot-solomon---PT says:

    Good stuff thank you a very good reminder... Happy new year !!!

  • John Fawkes says:

    I think I've suffered two or three minor disc injuries in my life- thankfully not requiring medical attention though. For someone prone to them, would you advocate going lower weight, higher reps on those exercises that cause them?

    • Marc Perry, CSCS, CPT says:

      Hey John, happy for Kenny to chime in, but as someone who has experienced slipped disc / surgery, I think the key is to improve the function of your body preferably working with a knowledge PT or trainer and avoid any exercises that cause any pain or issues.

      • Kenneth Leung, DPT says:

        While lower weight will help, proper form is ABSOLUTELY necessary. Marc is correct in that a knowledgeable PT or trainer may help you maintain that form, especially earlier on in the learning process. Avoid any trainer that allows your to round your when squatting! Start with higher reps and lower loads for safety before moving to higher weights if desired

  • Samdeep Gill says:

    Hi John. Thankyou for sharing such article. Now i have a pain in my right leg due to weight lifting through thaigh. It is unbearable i cant bend walk or stand. Please suggest me how an i get rid of this pain.

    • Kristin says:

      Hi Samdeep,

      I would recommend seeing a physical therapist, especially since you're experiencing pain with bending, walking, and standing. A physical therapist will be able to diagnose and treat the cause of your pain, and recommend exercises to help rehabilitate the injury. Good luck, and I hope you recovery quickly!

  • Daniel says:

    Nice article. I have knee pain that came unexpectedly during a week of rest from strength training. The pain is right below the knee cap as I'm walking but it's not too bad. Still I'm scheduled for an x-Ray. I often used the glute extension machine and did lunges holding 30lb before taking a break. Over 2 years ago, I injured same knee rising on a squat with considerably more weight. I don't do squats anymore but, I'm wondering if what's going on is a "whiplash after effect" of everything.

  • Kenneth Leung, DPT says:

    Hi Daniel. Good question. An x-ray most likely won't show much, but at least there's not much downside to getting one. Most likely your symptoms are not from a "whiplash after effect", but they can be related. This depends on your form and leg alignment when exercising. Unfortunately I can't be more specific as pain "below the knee cap" can be from a number of things. However, if you are able to do lunges and squats without pain during, immediately after, or the next two days, then generally they are safe for you. I hope that helps.

    • Daniel says:

      Thanks Kenneth. I realize now, the pain is more when I walk a longer spread, and the pain comes about as my toes leave the ground at the end of my step. I'm actually not sure if the pain is right at the knee cap or below. It's hard to tell. I will say, after I work out the lower body, the pain subsided. Is knee pain at the cap worse than below the cap? Am I describing "runner's knee?" I read that working the glutes and upper leg muscles can take pressure off the knee. Which exercise machines would you recommend for strengthening the knee muscles, tissues, and ligaments? For now I think I'm going to stay off the glute extension machine. I was using that a lot.
