“No pain, no gain” gets thrown around a lot in the world of fitness. But there are different degrees and causes of pain. Nearly everyone experiences lower back pain at least once in their life, often due to poor posture, so it’s not surprising that this is a common concern when it comes to working out. 

But this doesn't mean you have to accept back pain as a side effect of exercising. In fact, there are ways to prevent and treat back pain so you can continue your fitness journey without any interruptions.

Below, we'll discuss common causes of lower back pain after workouts, whether you should be worried about it, and tips for avoiding and managing back pain.

What are the causes of lower back pain after workouts?

Some soreness or tension in the lower back after a good workout is normal. It could just be your muscles adjusting to new movements. But if the pain gets worse and doesn't seem to quit, there might be an underlying root cause, such as:

Not warming up

Imagine the mental exhaustion and headache you’d feel attempting Wordle on zero sleep. That’s how your body feels when you rush into a workout, which is a recipe for pain and injuries. 

Warming up before a workout is crucial. It increases circulation to your muscles, making them more pliable and easier to move without pain. Getting straight to intense movements strains your muscles and joints, leaving you open to injury.

Here are some effective warm-up and cool-down exercises to get your mind and body ready for a workout:

  • Dynamic stretches like arm circles, leg swings, torso twists, and walking lunges
  • Foam rolling to release muscle and tissue tension and improve blood flow
  • 5–10 minutes of light jogging, jumping jacks, or cycling

Skipping stretching

It’s tempting to end a workout when you finish that last rep, but loosening up your muscles is essential. Stretching helps increase your range of motion, reduce muscle tension, and prevent injury. It also allows blood and nutrients to reach muscles faster, promoting better muscle recovery. 

For maximum back soothing, try doing full-body stretches, and give extra love to your:

  • Hamstrings
  • Hip flexors
  • Quadriceps
  • Glutes
  • Calves

Hold each stretch for 30–60 seconds in problem areas and repeat on both sides. Avoid bouncing during stretches, as it can cause tiny muscle tears, leading to pain and stiffness. Instead, focus on slow and controlled movements.

Overexertion

We know you’re pumped and excited to reach your goals and see how much weight you can lift or how fast you can complete a run. Your body just needs to catch up with that enthusiasm! Many injuries are preventable by taking it slow and steady. 

Gradual progression allows your body to adapt and build strength to handle heavier weights and intense movements. Without this slow build-up, you risk straining your muscles and joints, leading to back pain.

For weightlifting, start with lighter weights and focus on your form before increasing the weight load. Don’t feel pressured to lift at the same level as others in your gym or online class. Listen to your body and progress at a pace that feels comfortable for you. A good rule of thumb is to increase your weight by no more than 10% each week.

Poor form

Are you doing your exercises correctly? Even subtle errors in body positioning can increase the risk of back pain and injury. (That's why your trainer always reminds you to maintain proper form throughout your workout.🤯)

Poor form can lead to muscle imbalances, uneven weight distribution, and overexertion of certain muscles. This puts unnecessary strain on your back and may cause pain or discomfort.  

Some exercises where proper form is crucial for avoiding lower back pain include:

  • Deadlifts: These engage your core, glutes, and hamstrings, but if done incorrectly, they can put too much pressure on your lower back. Keep your back straight, hinge from your hips, and avoid rounding or arching your back.
  • Squats: A proper squat involves keeping your chest and head up, engaging your core, and pushing through your heels. If you round your back or let your knees cave in, you may end up with some lower back pain. 
  • Planks: Keep your body straight from head to heels, engage your core and glutes, and avoid arching or sagging your back. 

Remember, it's always better to do fewer repetitions and less weight with good form than more reps and heavier weight with poor form. If you aren’t sure whether you’re using the right form, a personal trainer can be a great resource. Trainwell gives you a real-life, on-demand trainer anywhere you are!

Should you be worried about back pain caused by working out?

The answer is . . . it depends. Some minor aches and pains are common and expected during and after a workout. Exercise challenges muscle groups and creates micro-tears. This is what makes your muscles stronger. 

You should expect some minor back tension or soreness:

  • During back exercises (Supermans, reverse flys, bent-over rows, etc.)
  • During core exercises (sit-ups, Russian twists, hanging leg raises, etc. — especially if done without proper form)
  • From 6–8 hours up to 72 hours post-workout

But you should stop working out and contact your doctor or a physical therapist if you have any:

  • Sharp pain
  • Sudden pain
  • Very localized pain
  • Pain lasting more than 72 hours
  • Numbness/tingling
  • Limb weakness
  • Pain that impacts your sleeping

There's a fine line between pushing yourself and overdoing it. Listen to your body cues as you exercise, and stop if you feel any sharp or sudden pain. It's better to take a break and reassess your form or weight load than to push through and risk injury.

How to prevent low back pain and back injury after working out

Along with proper form and gradual progression, here are three other ways to prevent back pain and injury after working out.

Incorporate core-strengthening exercises

A strong core helps support your back, improves balance and posture, and reduces the risk of injury from other exercises. Some excellent core-strengthening exercises to prevent lower back pain and improve overall strength and stability include:

  • Planks: Hold a push-up position with your elbows on the ground and your body in a straight line from head to heels. Engage your core and hold for 30 seconds to a minute.
  • Supermans: Lie on your stomach with your arms and legs extended. Lift your arms and legs off the ground simultaneously, engaging your core and glutes. Hold for 5–10 seconds and then lower back down.
  • Bird dog: Start on your hands and knees, with your wrists under your shoulders and your knees under your hips. Extend one arm and the opposite leg, keeping your back flat and engaging your core. Hold for a few seconds, and then switch to the other side.

For best results, incorporate these exercises into your routine 2–3 times per week. Switch between different variations and add additional exercises to continuously challenge your core muscles. 

Choose appropriate exercises and equipment

If you have existing back pain or are prone to it, it's important to choose exercises that won't aggravate your condition. By this, we mean avoid exercises that put too much strain on your back or involve sudden twisting or jerking motions, such as:

  • Traditional sit-ups: These put a lot of pressure on your lower back and can cause strain or pain. Partial or modified sit-ups are a safer alternative—and make sure you’re never pulling your neck!
  • High-impact twisty exercises: Russian twists, bicycle crunches, and similar exercises can strain the muscles in your lower back. Stick to low-impact exercises like yoga or Pilates for core and abdominal muscles. Notify your trainer about your back pain so they can suggest exercise modifications.
  • Heavy weightlifting: While lifting weights improves back health and helps build muscle, it’s essential to use proper form and avoid lifting more than you can handle. Gradually increase your weight load as you become stronger to prevent injury. If you’re completely new to an exercise targeting your lower back muscles, it’s best to start with your body weight when possible.

In addition to selecting appropriate exercises based on your strength and fitness levels, follow these tips to use equipment correctly and avoid back pain:

  • Use a mat or towel to cushion and support your spine during floor exercises.
  • Adjust weight machines and equipment to fit your body size and range of motion.
  • Ask for assistance or use a spotter when using free weights to ensure proper form and prevent injury.
  • When using resistance bands, avoid overreaching or straining your back. Keep the movements controlled and within a comfortable range.

Work with an experienced trainer

One of the best ways to prevent back pain and injury after working out is to work with an experienced personal trainer. With years of training and experience, they can:

  • Teach you proper form and technique for exercises to minimize strain
  • Design a personalized exercise program that takes into account pre-existing conditions and limitations
  • Monitor your progress and adjust your workouts accordingly
  • Ensure you are using equipment correctly and safely
  • Provide modifications or alternative exercises if you experience pain or discomfort
