@Abhishek Kumar I agree that exhaling is the key for oblique activation and that it puts the rib cage in a good position to maintain IAP and posture. However what do you think of PRI ? It's been debunked over and over again as pseudoscience by the entire evidence based physio community. I find PRI says interesting things, but their "corrective exercises" seem like total BS. Although I'd be happy to change my mind if I discover convincing evidence

@Abhishek Kumar thanks for sharing, I’ll have to look into it

@Angus Bradley Thanks mate, yeah it's been life destroying. Had to pause my career in sport science and have still not returned. I was resting in a deep squat after a heavy DL session, and my back felt stiff so I made it crack in torsion. Something popped, had sciatica for 24h and since then just back pain. No hernia on MRI or anything else. I've seen countless physios, chiros, neurosurgeons etc. What's worked best so far: A mix of the McGill method (I know...), hip mobility, loaded back extensions and side bends, bodybuilding with machines. Most helpful things to reduce pain (but didn't help me regain flexion): 1) Don't do movements that trigger the pain, no lumbar flexion 2) Walk 3 times a day 20min+ 3) McGill big 3 daily Other things that helped a bit: - McKenzie extensions - Nerve flossing/Nerve tension exercises What has failed: - ignoring the pain and continuing to run, jump, do handstands, pull ups and dips... I stopped all these and every time I start again it makes the back pain much worse the next day - "desensitising" approach by forcing flexion over multiple days Sorry for long message. But to answer your question, that's why I'm delaying returning to athletic training. I'd love to start again one day though, get on your plyo program etc. but it's feels far out. In the meantime I just do my 3 day split with the same machines and exercises over and over to regain a bit of muscle to not feel like a total looser
