You've probably seen the spreadsheets. Or maybe the YouTube thumbnails where Jeff Nippard, with his trademark calm, explains why your current routine is basically leaving gains on the table. Among all his programs, the Jeff Nippard upper lower split stands out because it’s not just a list of exercises. It's a calculated attempt to solve the "recovery vs. volume" puzzle that plagues every natural lifter.
Honestly, most people treat an upper/lower split like a chore. They hit chest and back on Monday, legs on Tuesday, and then spend the rest of the week wondering why their squats feel like death. Jeff's approach is different. It’s built on a foundation of "daily undulating periodization"—a fancy term for changing the intensity and reps every time you step into the gym.
Why the Jeff Nippard Upper Lower Split Actually Works
Standard splits often have you doing 3 sets of 10 for everything. Forever. It’s boring, and your body gets used to it fast. Jeff’s programs, specifically the Upper Lower Size and Strength series, use what he calls "wave loading."

Think of it like this. Week one is your intro. You’re getting the feel for the movements, maybe leaving two or three reps in the tank (RPE 7 or 8). Week two, you push harder. By week three, you’re hitting it heavy, maybe even touching failure on those final sets. Then, week four? You back off. This "mini-deload" isn't laziness; it's the only reason your joints won't start screaming at you by month two.
One thing that kinda surprises people is the exercise selection. You aren’t just doing the "Big 3" and going home. Jeff loves his "lengthened partials" and "eccentric-accentuated" reps. For example, in his lower body sessions, you might see a stiff-leg deadlift where you take a full four seconds to lower the bar. It burns. It’s also backed by research (like the 2022 Mayo study) showing that the stretch under tension is where the real growth happens.
The 4-Day vs. 6-Day Debate
You have options here. The 4-day split is the classic "work-work-rest-work-work-rest-rest" setup. It’s great for anyone with a life outside the gym. But Jeff also offers a 6-day version for the high-volume junkies.
- 4-Day Split: Focuses on high-quality sets. You hit each muscle group twice a week.
- 6-Day Split: Spreads the volume out. Individual workouts are shorter, but you're in the gym almost every day.
The mistake many lifters make is choosing the 6-day version because they think "more is better." If you’re a student or working 50 hours a week, you’ll probably crash. The 4-day Jeff Nippard upper lower routine is usually the sweet spot for recovery.
A Look at the "Upper 1" and "Lower 1" Structure
In the first Upper session of the week, Jeff usually prioritizes the heavy hitters. You’ll start with a Barbell Bench Press, but with specific cues—scapulae retracted, elbows at a 45-degree angle. He doesn't just want you to move the weight; he wants you to own the biomechanics.
Sample Upper #1 (Size and Strength Style)
- Barbell Bench Press: 3 sets of 6 (Strength focus)
- Lat Pulldown: 3 sets of 10 (Controlled eccentric)
- Overhead Press: 3 sets of 8 (Power focus)
- T-Bar Row: 3 sets of 12 (Hypertrophy focus)
- Isolation Work: Usually some tricep pushdowns or bicep curls to finish.
The "Lower 1" session is where the "Size and Strength" name earns its keep. It usually kicks off with the Back Squat. Jeff is big on the 15-degree toe flare and driving the knees out. After the heavy squats, you move into something like a Romanian Deadlift.
The variety is intentional. By mixing a "push" (squat) with a "pull" (RDL) in the same leg day, you’re hitting the entire posterior chain without one specific muscle group giving out too early.

Weak Point Prioritization: The Secret Sauce
This is where the program gets personal. Jeff doesn't believe in a one-size-fits-all approach for intermediate lifters. In his newer iterations, he includes "Weak Point" slots.
Basically, you pick two or three body parts—maybe your lateral delts or your calves—and you add specific volume for them on top of the base program. Jeff mentions in his own training that he adds extra bicep work because, well, who doesn't want bigger arms?
It's a smart move. It prevents the "blocky" look that some powerlifting-heavy splits can cause. You get the strength of a powerlifter with the aesthetics of a bodybuilder.

Common Misconceptions About the Split
People think "science-based" means "easy." It’s the opposite. Because the volume is lower than a traditional "bro split" (where you hit chest for 20 sets once a week), the intensity has to be higher. You can't just go through the motions.
Another myth: you need a home gym worth $50k. While Jeff uses some cool machines in his videos, most of the Jeff Nippard upper lower movements have easy substitutes. Don't have a Hack Squat? Use a Leg Press or even a heel-elevated Goblet Squat. The principles—tension, progressive overload, and recovery—stay the same.
How to Get Started the Right Way
If you’re ready to jump in, don’t just guess your weights. Jeff’s programs usually come with a tracking sheet or an Excel file. Use it.
- Find your 1RM: You need to know your maxes for the Big 3 (Squat, Bench, Deadlift) because many sets are based on a percentage of your 1RM.
- Respect the RPE: If the program says RPE 7, don't go to failure. If you blow your load in week one, you’ll have nothing left for the heavy stuff in week three.
- Track your LSRPE: That's "Last Set RPE." It tells you how hard that final set actually felt, which helps you decide if you should add weight next week.
- Film your sets: Jeff is a stickler for form. If your "squat" is actually a "good morning," the science won't help you.
The Jeff Nippard upper lower split is a commitment to training smarter. It's for the lifter who is tired of hitting plateaus and wants a roadmap that actually accounts for how the human body recovers. Start with the 4-day version, nail your form on the "Big 3" alternatives if needed, and actually take those deload weeks seriously. Your future self with significantly more muscle mass will thank you.
