Before this man is permitted to touch a barbell, he must first do his 30 min prep. Out comes the lacrosse ball, and he rolls his glute on it on the gym floor with the face of a man receiving terrible news over the phone. Then the foam roller, the full length of each leg, wincing theatrically at knots he has decided are there, even though science cannot yet see these knots. Then the little resistance band, looped above the knees for the side-steps, the monster walks, the clamshells, the entire physical-therapy waiting-room routine. Then the band gets hooked to the rack to distract his hip capsule, whatever that means, while he hangs off it and makes a face. Forty minutes in, glistening and deeply warmed up, he is at last ready to lift, except now he is tired and it is time to go home.

This used to be weird... I see it every day now

He calls this mobility. He has decided he is tight. He is always tight. Tightness is his whole personality and his eternal works-in-progress, and no amount of rolling ever finishes the job, which he reads as proof that he needs to roll more, rather than proof that the rolling does nothing.

Here is the secret nobody at the band table wants to hear. Most of what you are calling tightness is weakness. The muscle is not too short. It is uncontrolled past a certain range, so your nervous system, very sensibly, slams on the brakes and guards the position, and that guarding feels exactly like tension. You then attack the feeling with a lacrosse ball and buy yourself maybe ninety seconds of borrowed range, gone by your second working set, because you did not make anything stronger. You sedated the alarm. You did not fix anything.

Now, go ahead and tell this guy that he doesn't need to squat all the way down.

The actual cure for being weak and shaky at the bottom of a squat is, and I am sorry that an entire industry of rubber goods will hate this, squatting to the bottom and getting strong there. Load the range you cannot control until you can control it.

Load the range you cannot control until you can control it. Said it twice because it's that simple.

Strength in a position is what convinces the nervous system it is safe to let you into that position in the first place. That is mobility. Real mobility is just usable strength at the end of your range, and it is built with load, slowly, not purchased in rubber.

Some restrictions are valid though. Warming up is great and very useful. I am not telling you to stroll in cold and sprint for your life. I am telling you that prehab is, most of the time, bad programming in a lab coat holding a lacrosse ball, and that if your warm-up runs longer than your training, you do not have a mobility practice. You have an elaborate, sweaty, deeply sincere way of avoiding the one thing that would have actually changed your body, which is getting strong somewhere you currently are not. Find a way to strengthen whatever is tight and weak and you'll see how it relaxes.

    45 minute warmup, 9 minute lift, then surprised the lift isn't moving. My guy, you trained the warmup. You're going to set a really impressive clamshell PR and squat to parallel forever 😅

    the man receiving terrible news over the phone while rolling his glute. THAT'S MY GYM. there's a guy who does the exact wincing face at the foam roller every single morning and I have started timing my water breaks around his routine 💀 I have no opinion on the science I just feel so seen by the wincing

    Been lifting long enough to watch this exact pendulum swing three times, and the tell is always the same: people reach for a tool because progress is boring and invisible and a lacrosse ball feels like doing something. Sitting in a loaded bottom position twice a week for six months doesn't feel like anything until one day the floor is just there. No before-and-after photo, no ritual, nothing to film. That's why it loses to the band table every time. It's right, it's just not fun to watch yourself do.

    Mostly nodding, with one footnote from the trail side. Ankle dorsiflexion was my big restriction for years and rolling my calf did exactly the ninety-seconds-then-gone thing the post describes. What moved it was slow weighted dorsiflexion and just spending loaded time in the bottom of a deep split squat. So the mechanism held up for me. The part it undersells is that finding that range the first time, before there's anything to load, took a few weeks of boring positional work that looked suspiciously like the stuff he's mocking.

    "You sedated the alarm" is the whole post for me. I rolled my IT band like a religion for a year because it felt productive and tight stuff felt looser for about one set. Never got stronger, never got better, just got really good at rolling. Started actually loading the position and the tightness quietly left. Turns out it wasn't tight. It was weak and nervous.

    ok week-two person here, asking for real. he says warming up is great but prehab is bad, how do i tell which one i'm doing? right now my warmup is just copying whatever the guy next to me does. are the banded side-steps before squats the warmup part or the theater part

    Load the range you cannot control until you can control it. That line is the whole post and it's correct. The bottom of a squat is the cleanest example there is. Guys who can't sit in the hole add a band to the rack and tug on their hip for ten minutes, then go fail at parallel anyway. Pause squats in the bottom, a few weeks of them, did more for my depth than every lacrosse ball I ever owned. You don't roll your way into a position. You get strong there or you stay scared of it.

    "Forty minutes in, glistening and deeply warmed up, he is at last ready to lift, except now he is tired and it is time to go home." I felt that in my soul. This is the guy who has a 45 minute pre-lift routine and a 9 minute actual lift and wonders why he looks the same in March as he did in October. At least when I waste time in the gym I'm honest that I'm just talking about chicken and rice.

    I coach this for a living and the post is right about the average case and a little unfair to the edge cases. Most people do not need the band table. They need to add weight to the lift and stop avoiding the hard part. Agreed, fully.

    But "prehab is bad programming in a lab coat" sweeps up the people for whom a specific drill is the right call. The lifter rebuilding an ankle after a real sprain, the desk worker who genuinely cannot reach the bottom without the bar tipping them backward, those folks get five minutes of targeted work so the actual training can happen, then they train. The error isn't doing the drill. The error is the drill becoming the session, and never progressing past it. A principle done forever without getting harder isn't rehab, it's a hobby.

    Okay genuine beginner question because this is exactly the kind of thing I can't tell is a real rule or just loud. A coach at my gym had me doing clamshells and banded side-steps before squats and said it was to "wake up my glutes." Is that the theater you mean, or is there a version of it that's fine for someone who's eight months in and still wobbly at the bottom? I don't want to skip something that matters, but I also don't want a forty-minute routine before I've earned one.

  • Should you actually work out less?

    Let’s be honest about what most people are actually doing in the gym. It’s not overtraining in any meaningful sense, even though people love to say that when they feel a bit run down. Real overtraining requires real output. Heavy work, high intent, repeated exposure to something close to your limit. Most lifters are nowhere near that. What they are doing instead is just wasteful, training just hard enough to feel it, just sore enough to notice it the next day, just tired enough to believe it…

  • Are Bulgarian split squats far superior to back squats?

    If you are not a powerlifter, stop training legs like one. Actually, stop training everything like one. That is the argument. It took me years to realize that I didn't need to keep on lifting more and more on squats, since my legs didn't change after anyway. lbs would go up, muscles would stay pretty much the same. And the rest of my body paid the bill, less volume on arms, core, chest... Due to the focus on maintaining strong squat numbers. The problem is that seriousness, exhaustion, and...

  • Is prehab just cleanup for problems bad programming created?

    A lot of prehab is just cleaning up problems bad programming created in the first place. I do not mean rehab is fake, injuries happen, and some people genuinely need corrective work before normal training even feels possible again. But lately I have noticed how much modern lifting culture turns predictable programming mistakes into specialized rituals that get marketed back to people as advanced wisdom. The shoulder is probably the clearest example.

  • Is there really any such thing as 'mirror muscles'?

    One of the dumbest shifts in modern gym culture is the way people started talking about “mirror muscles” like they were fake muscles. Biceps. Side delts. Rear delts. Glutes trained directly. Rotator cuff work. Isolation exercises in general. Somehow all of this got framed as cosmetic fluff while endless compound lifting got rebranded as “functional.” And now there are people walking around with permanently irritated shoulders, aching elbows, unstable hips, and lower backs held together by…

  • Is sprinting the single best exercise for most people?

    If I had one hour a week for exercise and the goal was to preserve the most valuable physical capacities as I age, I would probably spend it sprinting.Not leg training, not running, not HIT. Pure sprinting, on hills and uneven terrain. Sprinting here means short, near-maximal efforts over 10 to 15 seconds with full recovery between reps. Not necessarily as an exercise, but as goal.

  • Do you actually train muscles, not movements?

    Most people do not have a movement problem. They have a weak-link problem. I am not talking about elite athletes, that's a minority and they're not on the internet reading me anyway. I am talking about ordinary people who want a body that can handle hard things without something dumb failing first. If your arms, shoulders, or grip give out before the job is done, I do not care what your squat and deadlift numbers look like. The body tells the truth fast.

  • Did your biceps stop growing because the weight is too light?

    People got way too obsessed with “perfect form” on curls. If the weight is so light that your torso doesn’t even need to stabilize, it’s probably not heavy enough to force growth. Look, don't spend all your time doing biceps curls trying not to move the shoulders. GET THEM HEAVY. See arnold: Heavy standing curls where you cheat the concentric a bit, then fight the eccentric under control, are brutally effective. 5 hard reps with a weight that actually scares you will build more real-world arm…

  • Do private coaches hold you back more often than they help?

    Something I see in the gym every day are private coaches (usually from the gym itself) being paid to walk around and give some basic exercises to the trainee. Most people walk into coaching with a simple assumption: I have a goal, and the coach is paid to get me there. But that is not true. The coach is also running a business, and businesses respond to incentives whether the owner is transparent about them or not.
