Weight training, nearly 8 months post op - worried as incisions feel more raised and tender…

You may be developing a hypertrophic scar. A return visit to your surgeon would be advised to provide a diagnosis and treatment options. It is unlikely that your weight training is contributing to the condition, and it should be safe to continue.

Dear claredegnan92,
I understand your concern. However, without a proper assessment, it would be difficult to determine what is wrong. It is best that you visit your plastic surgeon for further assessment or ask for a second opinion. Only after a thorough examination, you can get proper recommendations and advice.

Hello thank you for your question. skin will continue to natural stretch over time. It typically takes about one year for the surgical scars to mature. You can continue to train it shouldn't cause harm. If concerned speak with your plastic surgeon about your options and concerns.

You did not post photos, so I would suggest going back to your surgeon and seeing if your scars are progressing normally or becoming hypertrophic. There is treatment for the later.
