Some exercise programs can be dangerous. Here’s why I think P90X isn’t for everyone:

I’m just going to say something that you’re probably not going to want like to hear right at first but I love P90S not because of any results someone gets or doesn’t get but simply because it’s created a lot of low back pain patients for me it’s made me a lot of money. I wish I was joking but I’m not kidding and I’ve been meaning send them a thank you card or something but I haven’t gotten to it. The problem is that on that program, and in a lot of gyms, I see people trying to do abdominal exercises, or being asked to do abdominal exercises, that their abs are simply not strong enough to actually do with good form because the hip flexor is allowed to get involved in abdominal exercises, especially the psoas, and so at an anatomical level what happens, especially with abdominal exercises like leg lifts, or planks is a good example, the psoas runs from the inside kind of upper hip and attaches to the lumbar spine at all segment so it’s not just a hip flexor in that it pulls the hip up, but it pulls from the other direction too. So it’s pulling from the lumbar spine, what it does is it’ll pull you kind of down and into an anterior pelvic tilt or a low back arch. So what happens is that if they are repeatedly getting pulled into that position, it’s compressing all the structures in the lower back and then they end up with pain. If you have abdominals that are strong enough to counteract that, create that posterior pelvic tilt and you keep a neutral spine then you’re fine and they’re fine. But what I’ve seen is that a lot of people are doing exercises without that abdominal strength.
