Just a thought about the back. What do you do for a living? or are you in school?

It's amazing the damage that a bad seat can have on your lower back, back when i was driving 220+km a day for work my back hurt like hell, i could hardly pick up DB's to press them. Just adding a rolled up T-shirt behind my back helped worlds though in helping my sitting posture. It may not be the case for you, as it could be brought on by lifitng but it would be something to give some thought

I'm in school (lazy grad student).

This was no doubt brought on by my lifting, but most likely helped along by my very bad posture when sitting in chairs which I do most of the time. I'm a very on/off person when it comes to physical activity, so I'm either out there lifting, training, playing, or totally passive draped across a chair somehow with a very rounded back. I've always found it very uncomfortable to sit straight up, and my bad habits in this regard have no doubt led to a weaker lower back compared to my otherwise relatively strong physique.

If I go running my lower back will also be the very first thing to tire out - a long time before my legs or lungs go.

I have been trying to push myself into healthier sitting positions since the back started bothering me... something I no doubt should have done many years ago.

I've been staying at my parents place for a few days, so not much activity. I've mostly just been doing the planks, but am now going for a 3 minute normal plank, and then a 90 second one on each side. I'm also doing a load of bridges (not neck).

It might just be because the muscles get warmed up a lot doing this, but after the planks I can't really feel the soreness in my lower back at all. I'm hoping that's a good sign
