The Complete 12-Week Advanced Push/Pull/Legs and Core Strength Program for Runners

Written by Will Duru, BSc (Hons) Sport and Exercise Science, Award-winning Personal Trainer with over 10 years of experience in strength training and optimising recovery.
 
If you’re a runner who’s hit a performance plateau, you’re not alone. Many runners spend countless hours pounding the pavement, believing that more miles equals better performance. However, research shows that the missing piece in most runners’ training isn’t more running, it’s strategic strength training [1].
 
As a sport and exercise scientist with over a decade of experience training athletes, I’ve seen firsthand how proper strength training transforms running performance. The push/pull/legs methodology, combined with targeted core work, creates a balanced approach that enhances running economy whilst reducing injury risk.
 
This 12-week program is designed specifically for advanced runners who want to take their performance to the next level. Unlike generic gym programs, every exercise has been selected for its direct transfer to running performance. The program uses a two-phase approach with progressive overload principles to ensure continuous adaptation and improvement.

The Science Behind Strength Training for Runners

Running is a repetitive, single-leg activity that places enormous demands on your body. With each stride, you absorb forces equivalent to 2-3 times your body weight. Without adequate strength, these forces lead to fatigue, poor form, and eventually injury.
 
Research published in the Journal of Strength and Conditioning Research demonstrates that runners who incorporate strength training improve their running economy by 3-8% [2]. This improvement translates directly to faster race times and reduced perceived effort during training runs.
 
The key benefits of strength training for runners include:
 
Enhanced Running Economy: Stronger muscles require less oxygen to produce the same force output. This means you can maintain faster paces with less effort, particularly important during longer races.
 
Improved Power Output: Strength training increases your ability to generate force quickly. This enhanced power translates to more efficient stride mechanics and better performance in hills and sprint finishes.
 
Injury Prevention: Strong muscles, tendons, and ligaments better withstand the repetitive stress of running. Studies show that runners who strength train experience 50% fewer injuries compared to those who only run [3].
 
Better Running Form: Fatigue-resistant muscles maintain proper form longer. This is crucial during the latter stages of races when form typically deteriorates.

Why Push/Pull/Legs Works for Runners

The push/pull/legs split divides your training into three distinct movement patterns, allowing for optimal recovery whilst maintaining training frequency. 
 
This approach is particularly effective for runners because it:
 
Maximises Recovery: By training different muscle groups on different days, you allow adequate recovery time whilst maintaining a high training frequency.
 
Addresses Runner Imbalances: Most runners develop strength imbalances due to the repetitive nature of running. This program specifically targets commonly weak areas like the glutes, core, and upper body.
 
Fits Your Schedule: With only four sessions per week, this program integrates seamlessly with your running training without causing excessive fatigue.
 
Provides Progressive Structure: The systematic approach ensures you’re always challenging your body appropriately, leading to continuous improvements.
Understanding Single-Leg Training for Runners
Running is fundamentally a single-leg activity. At any given moment, you’re supported by one leg whilst the other swings through. This is why single-leg exercises form the foundation of this program’s leg training.
 
Single-leg exercises offer several advantages over bilateral movements:
 
Specificity: They closely mimic the demands of running, improving the transfer of strength gains to performance.
 
Balance and Stability: Single-leg training challenges your proprioceptive system, improving balance and reducing injury risk.
 
Imbalance Correction: These exercises reveal and correct strength differences between legs, which are common in runners.
 
Core Integration: Single-leg exercises require significant core activation, providing additional stability training.
The leg exercises in this program include single-leg press, single-leg extension, and single-leg curl. These machine-based exercises allow for controlled loading whilst maintaining the single-leg specificity crucial for runners.

Program Overview: Two-Phase Approach

This 12-week program is divided into two distinct phases, each designed to build upon the previous one:
Phase 1 (Weeks 1-6): Foundation Building
4 sets of 10-12 repetitions
Focus on movement quality and adaptation
Moderate weights with emphasis on form
Building work capacity and strength endurance
Phase 2 (Weeks 7-12): Strength Development
5 sets of 8-10 repetitions
Increased weights and intensity
Focus on maximal strength development
Enhanced power and performance transfer
Throughout both phases, progressive overload is applied systematically. This means gradually increasing the demands placed on your muscles through increased weight, additional sets, or enhanced exercise difficulty.
Training Schedule and Structure
The program follows a four-day training schedule that integrates perfectly with most running programs:
Monday: Push + Core (Upper body pushing muscles and core stability) Tuesday: Running or Rest Wednesday: Pull + Core (Upper body pulling muscles and core strength) Thursday: Running or Rest Friday: Legs (Single-leg focused lower body training) Saturday: Running (Long run or tempo work) Sunday: Rest or Easy Recovery Run
This schedule ensures adequate recovery between strength sessions whilst allowing flexibility for your running training. The 12reps app provides detailed exercise demonstrations and progress tracking to support your training journey.

Pull Day Workouts: Developing Posterior Chain Strength

Pull day targets the muscles responsible for pulling movements: back, biceps, and posterior chain. These muscles are often underdeveloped in runners, leading to poor posture and inefficient movement patterns.
 
Strong pull muscles maintain proper spinal alignment, support efficient breathing mechanics, and provide the stability needed for powerful arm swing. The posterior chain, including the glutes and hamstrings, generates the majority of propulsive force during running.
Pull Day Warm-up and Mobility (10-12 minutes)
Pull day preparation focuses on activating the posterior chain whilst addressing forward head posture and rounded shoulders common in runners.
 
General Warm-up (3-4 minutes):
Light cardio: 3-4 minutes of easy movement

Leg Day Workouts: Single-Leg Strength and Power

Leg day is where runners see the most direct performance benefits. This session focuses exclusively on single-leg exercises that closely mimic the demands of running whilst building strength, power, and stability.
The single-leg approach ensures balanced development between legs whilst challenging your stability and proprioceptive systems. This translates directly to improved running efficiency and reduced injury risk.
Leg Day Warm-up and Mobility (15-18 minutes)
Leg day requires the most comprehensive warm-up due to the complexity and intensity of single-leg exercises. This extended preparation addresses runner-specific tightness patterns whilst activating key stabilising muscles.

Implementation Guidelines: Getting Started

Starting a new strength training program requires careful planning and gradual progression. Here’s how to implement this program effectively whilst maintaining your running performance.
Week 1-2: Foundation Phase
Begin with lighter weights and focus on mastering movement patterns. Your primary goal is learning proper form and allowing your body to adapt to the new training stimulus. Many runners experience initial muscle soreness, which is normal and will decrease as your body adapts.
Start with weights that feel moderately challenging but allow you to complete all sets with perfect form. If you’re unsure about appropriate starting weights, begin conservatively and increase gradually.
Week 3-6: Building Phase
As movement patterns become more natural, begin increasing weights according to the progressive overload principles. You should feel challenged during the last 2-3 repetitions of each set whilst maintaining perfect form.
Monitor your running performance during this phase. You may initially feel some fatigue as your body adapts to the additional training load. This is temporary and will improve as your fitness develops.
Week 7-12: Strength Development Phase
The transition to Phase 2 marks a shift towards maximal strength development. The increased sets and heavier weights require greater focus on recovery and nutrition. Pay particular attention to sleep quality and post-workout nutrition during this phase.
Your running should feel noticeably easier as strength gains begin to transfer to performance. Many runners report improved hill running ability and better maintenance of pace during longer efforts.
Progressive Overload Strategies
Progressive overload is the gradual increase in training demands that drives adaptation and improvement. This program uses several methods to ensure continuous progress:
 
Weight Progression: The primary method involves increasing weight by 2.5-5% when you can complete all sets and reps with perfect form. For single-leg exercises, this progression may be slower due to the balance and stability demands.
 
Volume Progression: Moving from 4 sets in Phase 1 to 5 sets in Phase 2 increases training volume, providing a new stimulus for adaptation.
 
Intensity Progression: The shift from 10-12 reps to 8-10 reps with heavier weights increases training intensity, promoting strength development.
 
Exercise Progression: Some exercises become more challenging throughout the program, such as progressing from basic planks to plank-to-push-ups.
 
Track your progress using the 12reps app, which allows you to log weights, sets, and reps whilst providing visual progress tracking. This data helps ensure you’re applying progressive overload consistently.
Integrating Strength Training with Running
Successful integration of strength training with running requires careful attention to timing and recovery. Here’s how to optimise both aspects of your training:
Timing Considerations
Same Day Training: If you must train on the same day, complete your running first when it’s your priority session. For easy runs, strength training can be performed first without significant impact.
 
Recovery Timing: Allow at least 6 hours between high-intensity running and strength training when possible. This ensures adequate recovery and maintains quality in both sessions.
 
Weekly Planning: Schedule your hardest running sessions (intervals, tempo runs) on days when you’re not strength training or have completed easier strength sessions.
Managing Training Load
Monitor your overall training stress using subjective measures like perceived exertion and objective measures like resting heart rate. The 12reps app includes recovery tracking features to help manage your training load effectively.
 
Signs of excessive training load include:
Persistent fatigue lasting more than 48 hours
Declining running performance
Increased resting heart rate
Poor sleep quality
Loss of motivation
If you experience these symptoms, reduce training intensity or take an additional rest day.
Nutrition for Strength and Endurance
Proper nutrition supports both strength development and running performance. Your nutritional needs increase when combining strength training with running, particularly regarding protein intake and recovery nutrition.
Protein Requirements
Runners engaging in strength training require 1.6-2.2 grams of protein per kilogram of body weight daily [4]. This increased requirement supports muscle protein synthesis and recovery from both running and strength training.
Distribute protein intake throughout the day, aiming for 20-30 grams per meal. Post-workout protein intake within 2 hours optimises recovery and adaptation.
Carbohydrate Considerations
Maintain adequate carbohydrate intake to fuel both running and strength training. Aim for 5-7 grams per kilogram of body weight daily, adjusting based on training volume and intensity.
Time carbohydrate intake around training sessions, consuming 30-60 grams before strength training and 1-1.5 grams per kilogram of body weight within 2 hours post-exercise.
Hydration Strategies
Increased training volume elevates fluid requirements. Monitor urine colour as a simple hydration assessment tool, aiming for pale yellow throughout the day.
Consume 500-750ml of fluid 2-3 hours before training and 150-250ml every 15-20 minutes during longer sessions.
Recovery and Regeneration
Recovery is when adaptation occurs, making it equally important as the training itself. This program’s design allows for adequate recovery between sessions, but additional recovery strategies enhance results.
Sleep Optimisation
Aim for 7-9 hours of quality sleep nightly. Sleep is when growth hormone release peaks, supporting muscle recovery and adaptation. Create a consistent sleep schedule and optimise your sleep environment for quality rest.
Active Recovery Methods
Light movement on rest days promotes blood flow and aids recovery. Easy walking, gentle swimming, or yoga are excellent active recovery options that don’t interfere with adaptation.
Stress Management
Chronic stress elevates cortisol levels, which can impair recovery and adaptation. Incorporate stress management techniques like meditation, deep breathing, or relaxing hobbies into your routine.
Monitoring Progress and Adaptations
Track both strength and running performance to assess program effectiveness. The 12reps app provides comprehensive tracking tools for strength training metrics, whilst running apps can monitor performance changes.
Strength Metrics
Monitor increases in weights lifted, particularly for the major exercises like leg press, deadlifts, and pressing movements. Aim for consistent progression throughout the 12-week program.
Running Performance Indicators
Look for improvements in:
Perceived effort at given paces
Hill running performance
Ability to maintain pace during longer efforts
Recovery between running sessions
Body Composition Changes
Strength training often leads to favourable body composition changes, including increased muscle mass and reduced body fat percentage. These changes may not reflect on the scales but contribute to improved performance.
Troubleshooting Common Issues
Every runner will face challenges when implementing a new training program. Here are solutions to common issues:
Time Constraints
If time is limited, prioritise the leg day session as it provides the greatest running-specific benefits. Push and pull sessions can be combined into upper-body sessions when necessary.
Equipment Limitations
The program is designed for gym-based training, but modifications are possible. Resistance bands can substitute for cable exercises, and bodyweight variations can replace some weighted movements.
Plateau Breaking
If progress stalls, consider:
Deload week with reduced weights
Exercise variations to provide new stimulus
Increased rest periods for better recovery
Nutrition and sleep assessment
Expected Results and Timeline
Realistic expectations help maintain motivation throughout the program. Here’s what to expect
Weeks 1-3: Adaptation Phase
Initial muscle soreness that gradually decreases
Learning movement patterns and establishing routine
Possible temporary fatigue in running
Weeks 4-6: Early Gains Phase
Noticeable strength improvements
Reduced muscle soreness
Beginning to feel stronger during runs
