@jesusloverr Hi! I love this topic.
So if you look at the standard science, you are probably going to see warm-ups touted as beneficial for injury prevention. And I am not saying they are NOT beneficial for injury prevention or performance enhancement or any of that. I think they absolutely can be.
My point is that under certain circumstances, it seems a lot of people are fine SKIPPING the warm-up and staying injury-free and gaining from session to session. These circumstances are:
One: Strength and Sprint training (on soft surfaces) only. I am not talking about movement, sports, etc. For those, it's much harder to test. It may or may not work. For example, I didn't warm-up all the way from purple belt to black belt in BJJ and I stayed injury-free there too but I practiced differently than people. But for strength training and sprinting on soft surfaces, I have seen a lot of people at this point skip it and be fine.
Two: Minimal Effective Dose training. So the people I train who skip warm-up do it while training with MED. This means training with the dose that makes gains and then resting until fully recovered (ZERO aches or soreness) before next session. I go into each session ALREADY feeling loose and ready to go and I tell my trainees to do the same as well as anyone who ask about it on Instagram. If you're doing something like 3 sessions a week and you aren't fully recovered between sessions, you may want to warm-up.
Three: Full mobility. If you aren't able to get into the positions that you need to without a warm-up, you should warm-up. This one is objective. If you can't squat down all the way without a warm-up, then warm up. Now over time, you may find you can squat down without a warm-up and I use training tools that help people build that ability like Split Squats but at first, you may need it.
Fourth: Progressively working up to no warm-up. So if you squat 500 pounds but you need 10 sets to ramp up to it, please don't unrack 500 pounds tomorrow and start with that. Keep your ramp up sets but gradually start higher. So if you usually go 135, 225, 315, 405, 495, etc, start your NEXT session with something like 150, 245, 335 etc.
Five: Do it if you WANT to. If you simply prefer to warm-up, then I fully support that and I am happy to even help you tune it to make it better if I can. If you want to be able to SKIP your warm-up, I am happy to help that too.
As far as I know, there hasn't been a scientific study on these warm-up and these circumstances and if lab tested, it might show that the injury rate is low enough that you can hop right to it as long as you are under these circumstances.
Is the ingrained belief that we must warmup before workouts just indoctrinated into us
I think it's more like it's in us but WITHOUT nuance. The people who shout that you WILL be injured without a warm-up need more nuance because there are cases and circumstances where it appears to not be true. The people who say it only works for young people need more nuance since there are older trainees who do this too and are fine (ironically some of my older trainees are the who's think warm-ups are a waste of their time
). The people who say warm-ups are completely useless (like myself in the past... sorry about that ☹) need more nuance too because warm-ups CAN be beneficial as well. Basically, the hard statements need to be softened because there's more nuance.
Okay hopefully that clears it up and doesn't get me TOO much hate mail.
. Happy to answer any questions about it if there are any.
