Most people with back pain are given a sheet of exercises and told to do them. Most of those exercises do very little. A few make a real difference — and one or two commonly prescribed ones can genuinely aggravate a disc problem.
The principle: stability, not flexibility
The spine does not need to be more bendy. It needs to be better supported. The goal is a trunk that can hold the spine steady while your arms and legs do the work — which means endurance in the deep muscles, not extreme range of movement.
The exercises worth your time
Walking. Underrated and genuinely effective. Thirty minutes a day does more for most backs than any specific exercise.
The bird-dog. On hands and knees, extend one arm and the opposite leg, keeping the back completely still. Hold, then swap. This trains exactly what the spine needs: staying stable while the limbs move.
The side plank. Trains the muscles at the side of the trunk which control sideways load. Start from the knees if a full side plank is too much.
The glute bridge. Weak glutes force the lower back to do their job. Strengthening them removes load from the spine.
Hip flexor stretching. Hours of sitting shorten the hip flexors, which pulls the lower back into an arch. This is one place where stretching genuinely helps.
The ones to be careful with
Sit-ups and crunches. Repeatedly flexing a loaded spine is precisely the movement that stresses a disc. If you have a disc problem, these are a poor choice.
Toe touches. Loaded forward bending, especially first thing in the morning when the discs are most swollen with fluid, is a common way to aggravate a disc.
Aggressive twisting. Rotation under load is how many disc injuries happen in the first place.
How to actually do it
Consistency beats intensity. Ten minutes daily beats an hour once a week — spinal muscles respond to endurance training, not heroics. Build up gradually, and stop anything that reproduces leg pain, numbness or tingling: that is a nerve being irritated, and it means the exercise is wrong for you right now.
If you have an existing disc problem, get your programme set by a physiotherapist rather than the internet. The right exercise for a disc prolapse is not the same as the right exercise for spinal stenosis — and in some cases they are opposites.

Frequently Asked Questions
What is the best exercise for back pain?
Walking is the most consistently effective, and the most neglected. Beyond that, exercises that train trunk stability — the bird-dog, side plank and glute bridge — protect the spine better than stretching or sit-ups, because the spine needs support rather than extra flexibility.
Are sit-ups bad for your back?
For anyone with a disc problem, yes — sit-ups and crunches repeatedly flex a loaded spine, which is exactly the movement that stresses a disc. Trunk-stability exercises such as planks and bird-dogs achieve better core strength with far less spinal load.
Should I exercise if my back hurts?
Usually yes — gentle movement and walking help more than rest. However, stop any exercise that reproduces pain, numbness or tingling down the leg, as this indicates nerve irritation. If you have an existing disc problem, have your programme designed by a physiotherapist.
