As experienced in-home and virtual personal trainers, we understand the unique challenge of balancing endurance running with strength training. Many runners know they should lift weights to complement their runs, but they struggle with how to integrate both effectively. Here’s our tips for striking the right balance.

THE BENEFITS OF COMBINING DISTANCE RUNNING WITH STRENGTH TRAINING

Distance running builds cardiovascular endurance, stamina, and mental resilience. Strength training enhances muscle strength and joint stability. When programmed correctly, these two disciplines complement each other beautifully. “Strength work accomplishes three goals for runners: it prevents injuries by strengthening muscles and connective tissues; it helps you run faster by boosting neuromuscular coordination and power; and it improves your running economy by encouraging coordination and stride efficiency” (Runner’s World, 2023). 

The key is to view strength work as supportive (not competitive) to your running. Focusing on strength exercises that mimic running movements in particular builds a more efficient, injury-resistant body that can handle higher training volumes and faster speeds.

SUPPORTING SPEED & ENDURANCE

Your strength sessions should fit around your running schedule, not the other way around. We generally recommend our in-home and virtual training clients who are runners to aim for 2-3 strength sessions per week. Keeping these workouts moderate in volume ensures your body can recover without compromising your key running workouts.

Focus on compound lifts and functional movements like squats, lunges, deadlifts, and glute bridges to strengthen the posterior chain. Core work and upper-body strength are also important for maintaining form during long runs.

Avoid scheduling heavy lifting sessions right before speed or long-run days, allowing at least 24 hours between high-intensity strength and hard running workouts. This spacing prevents fatigue from one session limiting performance in the other. For most runners, the goal is not to build bulk, but to develop strong, resilient, and efficient muscles that support endurance and speed. Strength training should always serve your running, not compete with it!

PREVENTING OVERTRAINING

“Overtraining syndrome (OTS) is a condition that happens when you exercise too often or too intensely for long enough that it starts to hurt your body. It usually affects athletes — especially people training competitively” (Cleveland Clinic, 2024). Combining running and strength work increases training load, which can raise the risk of overtraining if recovery and nutrition aren’t prioritized. Overtraining can lead to persistent fatigue, declining performance, frequent illness, poor sleep, mood changes, or lingering soreness beyond a couple of days. 

If you start noticing that you’re working harder but performing worse, feeling unusually tired, or losing motivation, it’s a sign to scale back. Take an extra rest day, reduce intensity, or replace a hard session with easy cross-training or mobility work. 

Our in-home personal trainers in Toronto, Collingwood, London, Hamilton, and Ottawa (and virtual personal trainers everywhere) closely monitor signs of overtraining in clients through regular check-ins on sleep, mood, soreness, and performance. When we detect early signs of fatigue, we adjust training load and focus on recovery.

RECOVERY

Recovery is where progress truly happens. After each hard workout, your body needs time to rebuild and adapt. Getting 7-9 hours of quality sleep each night is one of the most powerful recovery tools available.

“Active recovery is often considered more beneficial than inactivity, resting completely, or sitting. It can keep blood flowing and help muscles recover and rebuild from intense physical activity” (Healthline, 2019). Easy runs, mobility work, yoga, or light stretching sessions can promote circulation without adding additional stress. Aim for at least one full rest day each week and one de-load week every three to four weeks, where training volume and intensity are reduced by about 20–30%.

Our programs can be designed to include guided recovery and stretching to monitor a client’s response to training, ensuring progress remains consistent and sustainable.

FUEL

Balancing both types of training requires smart fueling. You need enough energy to sustain endurance workouts while also supporting muscle recovery from strength sessions. 

Carbohydrates are your body’s main energy source for running, while protein aids in muscle repair and growth. Most active adults benefit from around 1.6 to 2.2 grams of protein per kilogram of body weight daily. Include carbohydrates from fruits, vegetables, and whole grains to maintain glycogen stores, especially on long run days. Healthy fats from sources like avocado, nuts, and fish support hormonal balance and recovery.

Timing is key: refuel within an hour after workouts with a combination of carbs and protein. Proper hydration is also crucial, especially during longer runs or strength sessions. 

Nielsen Fitness offers nutritional guidance based on training volume, goals, and lifestyle to ensure optimal recovery and performance.

FINAL THOUGHTS

Balancing distance running and weight training is about strategy, not intensity. The goal isn’t to do more, it’s to do better! Prioritize recovery, smart programming, and proper nutrition so your body can adapt and improve consistently.
