3-Day Split: Sets, Reps, and Beginner Meal Plans

By Kasim Javed Weights

Building strength and endurance doesn’t mean long hours in the gym. A 3-day split workout works well for beginners who want to build and maintain a steady routine. The balancing act between building muscle, improving conditioning, and prioritising recovery all compounds. Even the busiest schedules can adopt and commit to the three-day split.

For those starting in boxing, strength training, or general fitness, this guide breaks down an efficient 3-day split, the best sets and reps for strength, and a beginner-friendly meal plan to fuel muscle growth and recovery. Whether you’re training for performance or just looking to get stronger, this is the place to start.

What Is a 3-Day Split Workout?

A 3-day split is a workout plan that spreads your sessions across three days a week. Each day focuses on different muscles. The most common three-day split is push, pull, legs. Breaking up your days into chunks helps you build, rebuild, and recover.

For beginners, a simple and effective split is:

Day 1: Push (Chest, Shoulders, Triceps)
Day 2: Pull (Back, Biceps, Core)
Day 3: Legs & Conditioning (Quads, Hamstrings, Glutes, Boxing Drills)

This split helps you build muscle and keep your endurance under the cosh. It’s a great option for boxers, athletes, and those new to strength training. Combining compound lifts with dynamic moves, like kettlebells, builds strength and boosts endurance.

What are the Best Sets and Reps for Strength and Conditioning

How Many Sets and Reps Should You Do?

For beginners, focusing on the right combination of reps and sets is essential for building strength, endurance, and muscle. Thankfully, beginner gains are real but working on form is the priority before exploring rep ranges. When it comes to lifting weights, three sets and reps camps are divided into:

Strength & Power: 3-5 sets of 4-6 reps (heavier weight, longer rest)
Muscle Growth (Hypertrophy): 3-4 sets of 8-12 reps (moderate weight, controlled movement)
Endurance & Conditioning: 2-3 sets of 12-15 reps (lighter weight, minimal rest)

Rep Range Purpose:

Lower reps (4-6) = More strength and power.
Moderate reps (8-12) = Best for muscle building.
Higher reps (12-15) = Improves endurance and muscle stamina.

Example: Bench Press Breakdown

For Strength: 4 sets of 5 reps (heavy weight, 90 sec rest)
For Muscle Growth: 3 sets of 10 reps (moderate weight, 60 sec rest)
For Conditioning: 3 sets of 15 reps (lighter weight, 30 sec rest)

For boxing and combat sports, blending strength training with endurance-focused movements helps maintain power across multiple rounds. Despite this, it can be difficult to choose to focus on power or endurance. Sometimes it’s safer to go down the middle for a balanced approach.

How Hyrox and CrossFit Can Benefit a 3-Day Split

A 3-day split is great for those into functional fitness. It suits CrossFit and Hyrox training by mixing strength, endurance, and athletic conditioning. This type of training enhances many aspects of performance, including:

Explosive Power

Essential for boxing, MMA, and sports requiring rapid bursts of strength and speed.

Muscular Endurance

Crucial for high-intensity sports, ensuring you maintain performance throughout extended rounds or workouts.

Strength Under Fatigue

Helps you sustain power output even when exhausted, a key advantage in combat sports, football, and other endurance-based athletics.

Improved Work Capacity

CrossFit and Hyrox workouts push your body to adapt to high workloads, enhancing VO2 max and cardiovascular endurance.

Full-Body Coordination & Mobility

Incorporating functional movements improves balance, agility, and core stability, all critical for striking, grappling, and overall athletic performance.

By integrating sled pushes, battle ropes, kettlebell swings, rowing machine sprints, and box jumps, you develop functional strength that translates directly into boxing, MMA, and general fitness. This hybrid training approach ensures you build muscle, stay lean, and maintain endurance, making it an excellent addition to any 3-day split program.

Rest Days and Active Recovery

Take at least one full rest day between workouts to allow muscles to recover and grow. On rest days, do active recovery activities. Try walking, light cycling, yoga, foam rolling, or dynamic mobility work. They help lessen soreness, boost flexibility, and keep your body moving more easily.

The Best Nutrition for Strength Training

Training is only half the battle. Proper nutrition fuels your workouts, speeds up recovery, and helps build lean muscle. Don’t sleep on nutrition. Think of it as the life source that rebuilds and repairs your body during and after workouts. For weight loss, keep an eye on calories in and calories out.

For strength and endurance, focus on:

Protein: High-quality and varied sources of protein support muscle repair and growth.
Carbs: Fuels workouts and recovery. Some carbs are better than others, like complex carbohydrates. Refined ones are great for quick energy, but insulin/energy levels can spike.
Healthy fats: Fats received a bad wrap, especially in the mid-to-late 2000s. Fats are essential for hormone production and joint health.
Hydration: Hydration is critical for performance and endurance. According to Water Logic, only 53% of people in the UK are reaching their optimal hydration levels.

A balanced meal plan ensures steady energy levels, reduced soreness, and improved muscle growth. Dedicating a day off from your busy schedule to meal prep may just be the spark you need to ignite your fitness journey.

Beginner Meal Plan for Muscle Growth and Recovery

Breakfast: Pre-Workout Fuel

Scrambled eggs with wholegrain toast & avocado
Oatmeal with protein powder and berries
Greek yoghurt with nuts and honey

Lunch: Post-Workout Recovery

Grilled chicken, quinoa, and roasted vegetables
Lean beef stir-fry with rice and greens
Tuna wrap with spinach and hummus

Dinner: Muscle Repair

Salmon with sweet potato and steamed broccoli
Turkey mince chilli with brown rice
Tofu and vegetable curry with lentils

Snacks: Protein-Packed

Cottage cheese with almonds
Hard-boiled eggs and fruit
Protein bar/shake with banana

Eating enough protein and quality carbs around workouts improves muscle recovery and prevents fatigue. The more protein you eat, the more satiated your body will feel. If you don’t feel full after drastically increasing your protein intake, it may be worth talking to a GP or dietitian.

List of Cheap and Nutritious High-Protein Meal Ideas

The cost of living crisis has impacted every facet of life across the world. If you’re struggling financially, there is always a savvy way to reach your macros.

Eggs on Wholemeal Toast: Simple and protein-rich.
Tinned Tuna with Brown Rice: Quick and affordable.
Chicken and Sweet Potato: Easy to meal prep.
Lentil Soup: High in protein and fibre.
Greek Yoghurt or Skyr with Oats: Budget-friendly and nutritious.

You don’t need to spend a fortune on supplements, real food is just as effective. Don’t forget to use herbs and spices, as they can elevate the plainest of meals.
