Any time I try to work out my abs doing situps or using a machine lower back hurts before even feel it in abs. the correct form so what could problem be?

Here are a few possible reasons why your lower back might be hurting during abs exercises:

1. Incorrect Form:

- Make sure to keep your lower back pressed against the ground or the support of the machine during situps. Ensure your abdominal muscles are engaged and doing the majority of the work.

- Avoid arching your back or lifting your hips during the exercise. Maintain a neutral spine throughout the movement.

2. Weak Core:

- If your core muscles are weak, it may put extra strain on your lower back during abs exercises. Try to strengthen your core muscles by doing exercises like planks, bridges, and side planks regularly.

3. Tight Hip Flexors:

- Tight hip flexors can cause your lower back to arch during abs exercises. Stretch your hip flexors regularly to improve flexibility and reduce strain on your back.

4. Underlying Conditions:

- If the pain persists or is severe, it's best to consult a healthcare professional to rule out any underlying medical conditions that may be causing the discomfort.

Remember to start slowly, use proper form, and gradually increase the intensity of your abs exercises as your core strength improves. If the pain persists, consider seeking advice from a healthcare provider or a qualified fitness trainer.
