Sitting Up Straight & Back Problems

I notice when i sit i slouch a lot. could this lead to back problems when lifting?

Also, Is back pain a cause of weak abs, or a weak back> or both?

  1. yes.

  2. Could be either. It’s a very open question. I would say it’s more likely to be due to your poor posture than either, but strengthening your entire core musculature would be a very good idea.
