Why does my back hurt after running?

Repetitive impact, weak glutes, or tight hip flexors can leave the low back overworked.

Should I stop running?

Usually no. Cut mileage, add glute and core work, and check your shoes.

Do compression shorts help?

Some runners feel more supported with them, but core and hip strength do more long-term.

It can be if you feel leg symptoms or numbness. An AI assessment can help you think through possibilities.

Which strength work helps runners' backs?

Bird dogs, glute bridges, planks, and dead bugs are staples.

When should this be evaluated?

Sharp pain, radiating leg pain, or numbness warrants a check-in with a professional.
