To answer the question “is my deadlift plateau because of my form or my programming,” you only need one number: 85% of your one-rep max. If you can lift that weight for 3-5 clean reps, your form is likely solid enough and your programming is the problem. If your form breaks down even at this weight, you have a technique issue to fix first.
Let’s be honest. You’re here because you’re stuck. You walk up to the bar, see the same weight that’s been mocking you for weeks-maybe 225, maybe 315-and you already know what’s going to happen. You’ll pull, it’ll feel like it’s glued to the floor, and you’ll walk away frustrated.
You’ve probably tried just grinding it out, hoping that one day your body will magically get stronger. It won't. Hope is not a training strategy.
The problem isn’t that you’re not trying hard enough. The problem is you're trying to solve the wrong problem. You're guessing when you should be diagnosing.
Here’s the simple diagnostic test:
If you complete 3-5 reps and your back stays flat and your hips don’t shoot up first, your form is not the primary reason you’re plateauing. Your programming is failing you. For over 90% of people stuck in a plateau, this is the answer.
If your back rounds significantly or you can’t even get 1-2 reps, then your form is the immediate bottleneck. You can't build strength on a broken foundation.

Track your lifts. See your strength grow week by week.
Most lifters think getting stronger means constantly testing their one-rep max. This is the single biggest mistake that keeps people weak. Your one-rep max is a demonstration of strength, not a builder of it.
Strength is built in the 70-90% intensity range, for multiple sets and reps. This is where your body learns to recruit more muscle fibers and becomes more efficient at the movement. If you're only ever training at 95-100%+, you're just accumulating fatigue without building any real capacity.
This is why the 85% test is so revealing. It separates two types of failure: strength failure and technical failure.
Strength Failure is when you maintain perfect form, but the bar simply won’t move. Your muscles have hit their output limit for that day. This is a sign your programming isn't providing the right stimulus for growth.
Technical Failure is when your form breaks down to complete the lift. Your back rounds, your hips shoot up, or you hitch the bar up your thighs. This means your body doesn't know how to maintain the correct position under load. Your brain is choosing a weaker, less safe movement pattern just to get the weight up.
Constantly grinding out ugly reps at 95% of your max teaches your body to be good at one thing: lifting ugly. It reinforces bad motor patterns and increases your risk of injury, all while preventing you from getting stronger.
Your program's job is to build your strength in sub-maximal ranges so that when you do go for a new max, the strength is already there. You have the 85% test now. But knowing the test and having a record of your lifts are two different things. Can you look back 8 weeks and see your exact reps and sets? If you can't, you're not programming, you're just guessing.

Every workout is logged. Proof you're getting stronger.
Based on your 85% test results, you have one of two paths to follow for the next four weeks. Do not mix and match. Commit to one path, do the work, and your plateau will break.
Your goal is not to lift heavy. Your goal is to perform every single rep perfectly. This requires leaving your ego at the door and dropping the weight significantly. This feels wrong, but it's the only way to rebuild the movement pattern correctly.
Your Program:
Your Weekly Drills (Do these before your main sets):
Your form is good enough. You just need a smarter plan to stimulate new growth. We will use a simple block structure that manages volume and intensity to drive adaptation, followed by recovery.
Your Program (based on your true 1RM):
After this 4-week cycle, rest for 2-3 days and then go into the gym to test your strength. You can either test for a new 1-rep max or a new 3-rep max. You should expect to hit a 10-20 pound personal record.
Whether you're on the form path or the programming path, the first week or two of this new plan will feel psychologically uncomfortable. It will feel too easy, and you will be tempted to add more weight. Do not.
Progress is not always measured by how wrecked you feel after a workout. Real progress is measured by your capacity over time. The goal of this structured approach is to build you up, not break you down.
What Good Progress Looks Like:
Warning Signs It's Not Working:
Trust the process. The feeling of being “under-stimulated” for a short period is the prerequisite for breaking through your long-standing plateau.
Accessory lifts should support your deadlift, not distract from it. After your main deadlift work, pick two of the following exercises. Perform them for 3 sets of 8-12 reps. The goal is to build muscle in the weak areas, not to go extremely heavy. Good choices include barbell rows, lat pulldowns, glute-ham raises, and kettlebell swings.
For most intermediate lifters, pulling heavy once per week is the sweet spot. The deadlift is incredibly taxing on your central nervous system, and you need 5-7 days to fully recover and adapt. You can add a second, much lighter day (around 50-60% 1RM) to practice form if you are on Path 1.
A belt is a tool to increase performance, not a crutch for bad form. It works by giving your abs something to push against, increasing intra-abdominal pressure and spinal stability. Only use it on your heaviest sets (above 85%). Straps are for when your grip gives out before your back and legs. Use them on high-rep sets or your heaviest top set to ensure your grip isn't the limiting factor.
If you fail a rep with good form, you're done for the day on that lift. Rack the weight and move on. Trying again only digs a deeper recovery hole. If you fail because your form broke down, immediately strip 20-30% of the weight off the bar and perform one clean set of 3-5 reps to reinforce the correct motor pattern before you leave.
