Unlock the Potential of Concurrent Training: A Comprehensive Guide

A Comprehensive Guide to Concurrent Training 

When you hit the gym, you’re determined to build muscle fibers and shred fat. But should you focus all your energy on the weight rack, or should you log those treadmill miles, too? What if you could do both, getting a molecular response that maximizes your effort and achieves the best results? Enter concurrent training.

Concurrent training is the practical application of combining both strength workouts (like lifting weights) and cardiovascular training (like running or swimming) into your fitness routine. Unlike focusing solely on one or the other, this approach tackles your all-around fitness.

There’s been plenty of debate about whether this combo is effective, with some worrying that cardio might sabotage your strength gains. This is known as the “interference effect.” While it’s a valid concern, it’s not something to stop you. The interference of strength development is more of a hurdle to clear with smart planning.

 

What Is Concurrent Training?

Let’s break down concurrent strength training programs further. Think of it as a two-pronged attack on your aerobic fitness goals. You’re hitting the weights to build muscle size, increase strength, and boost your body power.

There are many individual training variables affected during the implementation of concurrent training programs. These have been measured via predicated maximal oxygen uptake, skeletal muscle adaptations, and bioelectric impedance analyzer. You can read about the science behind concurrent training, but it comes down to maximizing your body.

Then you add cardio sessions—running, cycling, swimming, whatever gets your heart pumping. The goal is to crank up your endurance and cardiovascular health, torch additional calories, and get that leaner physique.

This approach requires a more structured plan compared to just hitting the gym for random cardio or strength training sessions.

It’s about strategizing your workouts, understanding how different types of aerobic exercise impact your body composition, and finding the right balance between them. Get it dialed in, and you’ll unlock a higher level of overall fitness.

 

The Debate on Concurrent Training

The “interference effect” is the major buzzkill in the world of concurrent strength training. The concern is this: when you layer cardio on top of strength training, your body’s muscle protein synthesis ability and how it gains strength could be compromised. But how much truth is behind it?

Let’s talk about science for a moment. Previous studies have shown that combining endurance exercise (cardio) and concurrent resistance exercise (strength training) triggers certain neuromuscular adaptations in your body.

Essentially, your body receives mixed signals about what kind of performance to optimize for. Cardio wants long-lasting energy and efficiency, while strength training is all about explosive power and muscle growth. This clash can, in theory, slow down those muscle-building processes and endurance capacities.

The interference effect has been studied extensively, with a systematic review and meta-analysis documented in J. Sports Med and the Journal of Strength and Conditioning Research.

The reality is, that it seems to vary depending on several factors, such as:

• How many days per week you’re hitting cardio
• How intense it is
• Your overall fitness level

In untrained participants, the interference effect might be more pronounced, while those seasoned in athletic performance may handle it better.

Here’s the thing to remember: potential downsides shouldn’t derail your goals. It’s more about understanding the interference effect and optimizing your approach for maximum results.

Concurrent strength training done right can be a seriously powerful tool for improving your overall fitness, even with potential minor speed bumps in pure muscle gains along the way.

Why Concurrent Training Can Be Superior

Ready for the good news? When approached strategically, concurrent strength training can be more than just a compromise. Instead of hindering your progress, it can offer distinct advantages over focusing solely on strength or cardio.

Let’s talk about body fat loss. Cardio is well-known for burning calories, but with it, the effects of strength training are multiplied. As you build muscular strength, your body’s resting metabolic rate increases—you’re essentially turning your body into a calorie-burning machine, even when you’re at rest.

The fitness benefits extend far beyond looking leaner. Concurrent training seriously improves your overall health and physical performance.

You get the muscle power and explosiveness from strength training, paired with enhanced endurance and cardiorespiratory fitness, thanks to cardio. This translates to feeling stronger and having better physical capacities in everyday life, not just in the gym.

Now, here’s something that might surprise you. There’s research suggesting cardio can boost muscle growth compared to strength training alone.

It seems counterintuitive, but concurrent training studies show cycling to be an effective way to stimulate muscle hypertrophy, particularly in untrained individuals.

These relevant studies suggest that when combined with the right resistance exercises, aerobic activity can play a positive role in your muscle-building journey. So, you might add aerobic training to resistance training programs to help reach your peak power, thus improving your power output.

This combined strength training maximizes your endurance adaptations and physical fitness. Of course, it’s important to be realistic—maximizing pure muscle gains might require focusing mostly on strength for a period, but concurrent strength training can still give you a great foundation of strength and overall aerobic capacity.

How to Minimize the Interference Effect

Understanding the interference effect is the first step—now let’s focus on how to maximize the benefits of concurrent training effects while keeping any potential downsides in check.

Remember, optimizing your approach is crucial, and specific details (covered below) make the difference between gains and frustration.

Factors that influence the interference effect

While the interference effect is real, it’s not a one-size-fits-all scenario. Several factors influence how much cardio may affect your strength and muscle gains. Let’s examine the key culprits so you can optimize your workout plan:

• Type of cardio: It’s not all created equal. Running is high-impact, causing more muscle damage and fatigue compared to lower-impact options like cycling, swimming, or rowing. This matters as research in sports medicine and other publications demonstrates how excessive running can be more detrimental to muscle growth.

• Timing of workouts: Ideally, separate cardio and strength sessions by several hours—your body recovers better this way. If doing both in one day, prioritizing strength training first minimizes interference. It’s also important to consider timing meals around workouts to support your energy and recovery needs.

• Volume of cardio: How much is too much? This varies by person, but in general, several hours of cardio weekly can start cutting into gains. Moderation is key.

• Intensity of cardio: High-intensity interval training (HIIT), while great for fitness, taxes your body heavily. Too many HIIT sessions can hinder your lifting progress. Steady, low-intensity cardio is the safer bet for most of your cardio workouts when combined with strength.

• Calorie intake/diet: This is massive. Cardio burns calories, and if you’re not eating enough to make up for it, you’ll be in a calorie deficit. This hinders recovery and muscle growth. Ensure you’re eating enough to fuel both your workouts and your physique goals.

These factors don’t mean you have to ditch cardio altogether. It’s about identifying those that have the biggest impact on your specific recovery and performance—and then tailoring your training period accordingly.

 

Key guidelines for combining cardio and strength training

Understanding the potential pitfalls of interference is step one; now, let’s get to the solutions. Remember, consistency and smart planning will allow you to enjoy both strength and cardio benefits. These guidelines form your roadmap to success:

• Prioritize low-impact cardio: Opt for cycling, swimming, rowing, and even brisk walking—they’re kinder to your muscles, letting you recover faster for strength sessions. Limit running, if possible.

• Limit cardio volume and duration: Aim to keep most cardio sessions fairly short. Consider 2-3 hours of cardio weekly as your general limit, with most sessions under an hour long.

• Separate workouts when possible: Cardio one day, strength training the next—this is ideal for recovery. If combining in one day, space them out and do weights first.

• Prioritize strength training goals: While concurrent training benefits both, lean towards prioritizing your strength and muscle-building. Fit the cardio around your strength program, not the other way around.

• Increase cardio volume gradually: Start slow! Overdoing it initially can cause issues. Your body has gradual adaptive responses—add cardio duration and high-intensity strength training in small increments for sustainable progress.

• Focus on low-intensity cardio mostly: Save those High-Intensity Interval Training sessions for 1-2 times per week max. Most workouts should be at a steady pace you can easily talk during.

• Avoid extreme fatigue in workouts: Going to full exhaustion all the time backfires. Leave a little in the tank, both in your cardio and endurance training sessions.

• Deload regularly: Rest and recovery are non-negotiable with concurrent aerobic training. Deload weeks (dropping both cardio and strength volume/intensity) every month or two help you recharge and avoid burnout.

These guidelines aren’t rigid rules but rather the framework for creating sustainable concurrent training. It’s about finding the balance that works for you, pushing your limits without compromising your results in either cardio or strength training status.

The Wrong Way to Do Concurrent Training

We’ve been talking about the interference effect—now let’s look at how it can be intensified in ways that don’t reflect real-world training.

It’s important to understand that much of the research on concurrent training is designed to highlight the potential interference, often taking it to extremes for better analysis.

Let’s take a classic example: Robert Hickson’s 1980 study. Hickson, both a runner and powerlifter, wanted to investigate if his two passions were clashing.

He devised a study with participants split into three groups: training for strength only, cardio only, or a combination of both programs.

The results? Shockingly, the combined group gained similar muscle mass as the strength-only group but saw significantly reduced strength gains. They also gained endurance comparable to the cardio-only group. This painted a grim picture of concurrent training.

Here’s the problem: Hickson’s study used an unrealistic and excessive training load. Participants did intense lower-body strength sessions at five weeks of training.

And on top of that, nearly four hours of running and cycling weekly. Of course, there was major interference! It’s a wonder they gained any muscle at all.

This study highlights how some research amplifies the interference effect for the sake of measurement. This doesn’t mean concurrent training is always a bad idea—far from it.

However, it shows that a poorly designed training program can severely diminish your results. The takeaway? Don’t replicate the mistakes of past research in your training journey.
