Mild back soreness when you start the gym is common and usually isn't serious. It often comes from doing too much too soon, weak core and hip muscles or poor form on lifts like deadlifts and rows. Cut the weight, fix your technique, keep moving and see a doctor if the pain is sharp, spreads down a leg or doesn't ease.
If you want a gentle way back in, use the 4-week restart plan for men over 30.
Why does your back hurt when you start training?
Your back hurts at first because your body isn't used to the load. Common causes are lifting too heavy, rounding your back on deadlifts and rows, sitting all day and having weak glutes and core. Muscle soreness that peaks a day or two after training is normal. Sharp pain in the moment is not.
I'm a coach, not a doctor, so use this as general guidance. MedlinePlus explains common causes of back pain.
What should you change in your training?
Lower the weight, slow down and focus on form. Keep sessions short and add load gradually, so your back has time to adapt to the work you're asking it to do. These changes help most.
- Go lighter on deadlifts, rows and squats until your form is solid.
- Brace your core and keep your back flat, not rounded or over-arched.
- Use a hip hinge, pushing hips back instead of bending from the waist.
- Warm up with a few minutes of walking and gentle movement.
- Strengthen glutes and core with bridges, planks and dead bugs.
If a move hurts, swap it for an easier one. For more on getting going safely, read how to do your first workout after a long break.
Should you rest or keep moving?
For most mild back pain, keep moving gently rather than resting in bed. The American College of Physicians' guideline on low back pain recommends non-drug treatments first, and exercise is one of the options for longer-lasting pain. You can read the ACP guideline for the details.
Walking is a good place to start. Avoid exercises that make the pain worse, and build back up slowly.
When should you see a doctor?
See a doctor before you carry on training if your back pain comes with any of the warning signs below, because they can point to something that needs proper medical care rather than a few lighter sessions:
- Pain that spreads down your leg, with numbness or weakness.
- Pain after a fall or injury.
- Fever with back pain.
- Trouble controlling your bladder or bowels. This needs urgent care.
- Pain that doesn't improve after a few weeks.
Once you're cleared, begin the 4-week restart plan. Knees giving you trouble too? See exercise with bad knees.
Your next step
Back pain at the start of training is common. Go lighter, hinge from the hips, strengthen your core and glutes and keep walking. Get checked if you notice any red flags. Then follow the 4-week restart plan.
