Upper Lower Split: The Complete 4-Day Workout Program 2026 Guide

Unlike some of the other workout programs, there’s a heavy squat and heavy deadlift on the same day, which may not be ideal for optimal performance. As far as progression goes, a specific rep range and number of sets for the main lifts (i.e. 4 sets x 3-5 reps) is prescribed. Once you perform all sets with 1-2 reps above that rep range, increase the weight by 5 lbs for the next week. However, the upper body days are separated by pull and push exercises.

Upper Lower Split For Fat Loss

Did you know that the “perfect” workout routine is often the one you are most likely to follow for years, not weeks? This pursuit of excellence is something we deeply value at BUBS Naturals. This structure supports the principle of training frequency, allowing you to work each muscle group 2-3 times a week. Research has consistently shown that this frequency range is effective for building both strength and muscle mass while offering adequate recovery time (1). A full body training split enables you to perform compound movements more frequently when compared to other splits.

Improved Exercise Quality

The volumes fall within the range of 10 – 20 sets for each muscle each week which seems to be within the optimal range for muscle growth. This range of sets can also be accommodated in the 2 – 3 sessions of training per week as this seems to be ideal. Full body workouts do have the downside of being longer in duration. Even though unimeal reviews they are performed only 3 days a week, this time constraint may become less than ideal. Overall, the best upper/lower split seems to be the 4-day one, as it offers a consistent, relatively flexible schedule, the optimal training frequency for intermediates, and plenty of volume.

It Loses Efficacy Over Time

Instead of hitting muscles often with less work, they go for a massive stimulus in a single, high-volume session. A classic “chest day,” for example, might include five or six different exercises, pushing those muscles to their absolute limit. Each muscle group gets worked twice per week, which lines up well with what the research supports. A meta-analysis by Brad Schoenfeld found that training a muscle group twice per week produced slightly better growth than once per week. The effect isn’t dramatic, but it’s consistent enough to matter over months of training.

Start your sessions with these lifts to ensure peak performance while you’re at your freshest. Lower-body exercises, particularly compound movements such as squats and deadlifts, frequently engage larger muscle groups and central nervous system resources (6). Therefore, you may need slightly less volume on lower-body days to allow for adequate recovery. For example, while you may complete working sets on an upper-body day, 9-12 sets for a lower-body day could be sufficient.

• Creatine is one of the most researched supplements in the world, proven to support ATP production, which allows you to squeeze out those last two vital reps that trigger growth.
• Some of the best accessory exercises are the non-bolded exercises in the Big Six section.
• For some people, training a lift once per week is not enough, and their strength barely improves because they can’t solidify proper lifting form.
• The trick is knowing which one to pull out of the toolbox and when.
• Now, the reason we specifically chose this exercise for this workout, is because it really emphasizes the lower chest or abdominal head.
• Additionally, the timing of pre and post-workout meals significantly impacts muscle recovery and growth, emphasizing the importance of nutrient timing.

DAY UPPER LOWER WORKOUT PLAN

For most people, a 4-day upper/lower workout program is ideal for building muscle and gaining strength. Like the nSuns program, the load you use for your main compound lifts is calculated using your 1-rep max. Throughout the program, the main compound lifts are trained between ~65-70% of the lifter’s 1-rep max. Since this is a powerbuilding program, accessory exercises for the lower and upper body are added after the main compound lift is performed to stimulate muscle growth.

Main and Assistance Lifts

One of the most popular and effective training structures is the upper/lower split. Yup, even with all else (total weekly volume, exercise selection, rep ranges, etc.) being equal. This is what most people would consider to be the “classic” version of a full body routine. As you can see, it’s a 3-day split performed in an every-other-day format with two days off at the end. In this article, I’ll cover everything you need to know about it (including the 2, 3, and 4-day versions of the full body split), and provide three free workout routines for you to use. When your number one goal is losing fat, the “full-body vs. split” debate gets a lot simpler.

However, in specific cases, activating the core first can serve as a warm-up to enhance performance for lifters who struggle with bracing or posture control. Recovery is as important to progress as the workouts themselves (4). Splitting your sessions into upper and lower body focuses builds recovery into the program. For example, you can prioritize heavier compound lifts early in the week, followed by lighter accessory exercises targeting specific muscles later. This diversity in loading and movement patterns will keep your muscles challenged and foster consistent growth (3). If you find yourself with limited days to effectively train, you might try doing just one upper and one lower session per week for a total of two weekly workouts.

The “Upper Body” Day

Do one of those heavy warm-up sets, rest for 3 minutes, then begin your first working set. Barbell curls and overhead extensions are next, supersetted together. I use an angled curl bar for both, using the same load for both exercises, bringing all sets to the cusp of failure.

The Best Workout Split for Intermediate/Advanced Lifters

Incorporating these vital lifts ensures a comprehensive approach to strength training and full-body workout routines. The upper lower split workout routine is a type of workout plan that divides training days into upper body and lower body workouts. This approach allows for proper recovery time between muscle groups, focusing on different areas of the body on different days. It is a popular option for efficiently splitting workouts and is designed for both muscle building and strength training. This workout routine offers a structured approach to targeting specific muscle groups, providing a balanced and effective method for overall strength and muscle growth.

Fuel Your Fitness

An upper-lower-full-body split is a workout structure that divides training sessions into three distinct focuses over the course of a week. Each session targets different areas of the body or movement patterns to ensure balanced development, optimal recovery, and efficient use of training time. And by a higher frequency of training, I’m talking about a workout routine that involves lifting weights 4-6 days a week. If you struggle to keep your energy and intensity up through long full-body workouts while you’re in a caloric deficit, then try a split training program. When you start weight training, you’ll see progress almost no matter what you do in the gym.

Why Choose Full Body Workouts?

And that training one day a week does not allow one to attain the necessary volume which most practiced lifters require. The 6 days split may be right in the sweet spot of training frequency. Another popular option, which is basically the opposite of the bro-split, is a full body workout routine that is most commonly done as a 3 day workout split. An example of this is the upper/lower split, which is a 4 day workout split. Essentially, the upper body is trained on one day and the lower body on the next. It’s certainly effective in the sense that it will lead to muscle being gained.

After you come back from a deload week, you can do things like swapping out exercises, changing the order of your exercises, and altering your rep schemes. For example, deadlifts and squats can be effective in the 1-8 rep range, but bent over rows will be better in the 6-12 rep range. Again, your core is going to get plenty of work from the main lifts as well. If you’re interested in learning more about correct form for a few of these moves, check out our articles on leg lifts and the hanging leg raise. When it comes to your core, it is going to be worked heavily for stability demands with your main lifts, so it won’t really need too much additional work.
