The Real Reason Your Speed Work Stalls (You Never Find Out Where It Breaks)

Speed · 8 min read · October 29, 2026

You've done the slow part. You set the click, played the lick cleanly, nudged it up a few BPM, played it again. Weeks of that. And now you're parked at a tempo where the lick sort of works on a good night and falls apart on a bad one. So you do what everyone does: you drop the click back down, play it clean again to feel better, and creep back up to the same wall.

That loop has one big hole in it. At no point do you find out why the lick breaks at the faster tempo. You feel that it's messy, you back off, and the actual problem stays exactly where it was.

We recently asked a big guitar group on Facebook a simple question: how do you actually structure your speed work? Start super slow and add a few BPM at a time? Short bursts above your max? Push to the limit, then drop back and lock it in? The answers didn't all agree, but the most useful ones shared one idea that most practice routines skip completely: going past your limit on purpose, so you can find out exactly where you fall apart.

The Method: Build Up, Overshoot, Diagnose, Fix

The answer that got the most nods came from one player who laid it out in four steps. It's an approach often credited to Jason Becker and to Shaun Baxter, one of the key tutors at GIT in the UK. Here it is in plain terms:

Build up methodically. Raise the tempo a few BPM at a time until you hit your limit for precision. Not your limit for survival. The fastest tempo where the lick still comes out clean.
Overshoot on purpose. Crank the metronome up by a substantial amount, not 2 or 3 BPM but a real jump, and just go for it.
Diagnose. You'll make mistakes. But a lot of the phrase will actually be accurate, and that's the interesting part. The mistakes won't be spread evenly. They'll cluster in a few specific spots. Find them.
Fix and repeat. Work on the exact spot that broke, then run the loop again until you're happy with the result.

Most players do step 1. The braver ones add step 2. Almost nobody does steps 3 and 4, and that's where the progress is hiding.

Why Overshooting Works

Just under your limit, everything feels equally fragile. You can't tell which parts are solid and which are held up by luck and concentration.

Push well past your limit and the picture gets very clear, very fast. The solid parts of the phrase stay solid. The weak links snap. Overshooting is basically a stress test: it shows you the two or three notes that are actually stopping you, instead of a general feeling that "it gets messy around 140."

Another player in the thread pushed the same idea even further: crank the metronome to the target tempo straight away and add notes one at a time until you can play the whole section at that speed. His reasoning was that building up slowly is like thinking running is just faster walking. They're different movements. Take it as far as you like, but the core point holds: some problems simply don't exist at slow tempos, so you'll never find them there.

Just don't treat the overshoot as your new tempo. It's a diagnostic: you go up there to collect information, then come back down and use it. If you want to know why living at the edge all the time backfires, we covered it in The Real Reason You're Stuck at 120 BPM.

Where It Usually Breaks

"Examine where you went wrong" is easy to say. In practice, the breaks almost always fall into a short list. When you overshoot, listen for these:

String crossings. The lick is clean on one string and falls apart the moment you change strings, especially when the pick has to jump over a string to get to the next one.
Hand synchronization. Both hands are fast enough, but they're not arriving at the same time. The picking hand gets a hair ahead of the fretting hand, and the note comes out choked or doubled. This is the big one. We went deep on it in Hand Synchronization: The Silent Killer of Clean Playing.
Timing. The notes are all there but they're not evenly spaced. You rush the start of the phrase and drag the end, or the run lands ahead of the click.
Uneven fretting fingers. Some notes are loud and some barely sound, often the ones played with your weaker fingers.

One experienced player in the thread made a sharp observation here. For most right-handed players, the picking hand is fairly metronomic even when it's inaccurate. It keeps going. The errors tend to come from the sync between the two hands, or from the fretting hand playing unevenly. So when a fast run sounds sloppy, don't automatically blame your picking. Check the fretting hand and the sync first.

How to Diagnose Properly

Your ears lie to you at speed. Your brain fills in the notes it knows are supposed to be there. So the diagnose step needs to be more than a vague impression:

Record the overshoot. A phone on the music stand is enough. Listen back one small chunk of the phrase at a time.
Name the spot. Not "the middle part." The exact two or three notes where it goes wrong, and which of the categories above it falls into.
Isolate it. Loop only that small fragment, plus a note on either side, so the transition into and out of it gets trained too. Replaying the whole phrase twenty times means nineteen reps of stuff that already works.
Fix it at a tempo where you can feel the problem. Sometimes that's slow, so you can watch exactly what each hand does. Sometimes it's close to the target tempo, because the problem only appears at speed.

Then put the fragment back into the phrase and run the loop again. If the weak spot has moved somewhere else, that's good news: the old one is fixed.

Count It, Don't Just Follow It

A different reply in the thread came from a rhythm angle, and it's worth stealing even if you're a lead player. His routine: start at 60 BPM with a sixteenth-note workout, play for a couple of minutes, raise the tempo by 8 BPM, repeat. When it gets too fast, drop back by 4. That's your top speed for the day.

The important detail was this: count the subdivision out loud. "1 e & a, 2 e & a." If you don't count, you're just reacting to the metronome. Counting puts you in charge of the time. Then record yourself, and record the same thing a week later, so you hear the difference instead of guessing.

That fits with another answer that summed it up in one line: the pillar of speed is timing. Dexterity is the second layer, flexibility comes after that. If your timing isn't solid, extra speed only makes the mess louder. If timing is your weak spot, The Real Reason Your Riffs Don't Sound Tight is a good next read.

Bursts, Slow Work, and Why Nobody Has the One True Method

One player said he simply starts at a comfortable speed, slowly increases it, and mixes in some bursts. After a year of serious picking-hand work, his takeaway wasn't a trick: work on it regularly and get into the details of the technique.

Another reply made a point that's easy to forget: listen to the players who got where you want to go, and notice they didn't all get there the same way. Don't waste months searching for the single correct method.

So here's how the pieces fit together:

Slow, clean build-up gives you a reliable base and teaches the movement.
Overshooting shows you exactly where that movement breaks.
Targeted fixing turns the weak spot into a solid one.
Counting and recording keep your timing honest and give you proof that it's working.

Speed itself is the result, not the thing you train directly. That's the whole argument of Speed Is a By-Product of Accuracy. And if you want a refresher on making the click your ally rather than your enemy, see How to Actually Practice With a Metronome.

Then Make It Music

Once the mechanics are in place, the same experienced player had one more piece of advice: all this isn't necessarily musical, so don't stop there. Put accents on different notes within your phrases. Change the note values, moving from sixteenths to sixteenth triplets and trying odd-numbered groupings. Play with asymmetrical phrasing. Writing short études around the passages that give you trouble can also pay off.

It's also a great test: if you can move the accent around in a lick and it still sounds clean, you actually own it.

Set This Up in ShredForge

The loop above needs three things: a way to run different tempos in one session, an honest judge for the diagnose step, and a way to see whether you're actually moving forward.

Session Builder. Each block in a session can have its own tempo. Put your clean build-up tempo in one block and your overshoot in the next, so the loop runs without you stopping to fiddle with the metronome.
Real-time audio analysis. This is the honest second pair of ears. It tells you whether you played clean or sloppy, and whether you stayed locked to the tempo or drifted. That's exactly what you need when you overshoot and want to know what actually happened, not what you think happened.
Skill Tree. Your progress is tracked as you go, so you can see the technique moving forward instead of guessing from one good night.

Try it free at shredforge.app. It runs in your browser, so there's nothing to install.

FAQ

How far past my limit should I overshoot?

Far enough that the phrase clearly breaks, but not so far that it turns into noise and you can't tell which notes went wrong. A jump of 10 to 20% above your clean tempo is a reasonable place to start. Adjust from there.

Isn't practicing mistakes a bad idea?

It is if you do it all the time. The overshoot is a short diagnostic pass, a few attempts, not your main practice. Most of your reps should still be clean ones.
