Most back pain advice treats the symptom. Stretch it, rest it, get it massaged... and it comes back the moment you sit down again.
Here's the thing: your lower back usually isn't the problem. It's the victim.
When your hips lose their usable range and your glutes and core stop doing their job, your lumbar spine picks up the slack. Every time you bend, lift, twist or get up from your chair, it's doing extra work it was never built for. No amount of stretching fixes that.
Back Bulletproof™ goes after the cause. First you restore real, usable range in your hips. Then you teach your body to own that range under load, so your back is protected by strength, not by avoiding movement.
Because mobility is strength, not stretching.
