Strength Training Myths Endurance Athletes Need to Stop Believing

Endurance athletes often overlook strength training, fearing it might hinder their performance or fail to yield any benefits specific to their sport. But here's the truth: strength training can dramatically enhance your endurance, reduce your risk of injury, and improve overall performance on the track, trail, or bike. However, to fully appreciate its benefits, it's crucial to debunk common myths that cloud judgment.

If you're an endurance athlete hesitating to incorporate strength training into your routine, this guide is for you. Together, we’ll tackle some widespread misconceptions and explore how these myths might be holding you back.

Myth 1: Strength Training Will Make You Bulky

Many endurance athletes avoid strength training out of a fear of 'getting bulky' and slowing down. It’s an understandable concern, as most associate noticeable muscle growth with bodybuilders.

The Science Behind Muscle Growth

Getting bulky requires intense, targeted training and a calorie surplus, as muscle growth (hypertrophy) depends on specific conditions. Endurance athletes, who typically consume calories to support high-volume aerobic training, rarely meet these criteria. Their primary focus on cardio inherently limits significant muscle mass gain.

Why More Muscle Is an Asset

Building moderate muscle mass enhances power and efficiency. For example:

• Cyclists use leg strength to generate more power with every pedal stroke.
• Runners build more resilience in key muscle groups to prevent fatigue during long distances.

Bottom line? Strength training won't turn you into the Hulk, but it will give you an edge during competition.

Myth 2: Endurance Athletes Don't Need Strength Training

Endurance athletes might assume that running, cycling, or swimming is enough to strengthen the muscles they use. However, these repetitive motions can create muscular imbalances, leading to overuse injuries and inefficiency.

Benefits of Strength Training for Endurance Athletes

Strength training addresses weak points in your structure, improving biomechanics and preventing injuries like runner's knee or IT band syndrome. For example:

• A stronger core improves running posture and reduces fatigue.
• Strengthened glutes help cyclists generate more force with each pedal stroke.

Ignore this myth, and you could be leaving speed and injury resistance on the table.

Myth 3: Strength Training Will Negatively Impact Endurance Performance

Some athletes fear that strength training will slow them down or undermine their endurance sessions. But with proper planning, strength and endurance training complement one another rather than clash.

The Golden Rule of Programming

Strategically time your strength workouts around your endurance training:

• Heavy lifting days should follow lighter endurance days.
• Give yourself adequate recovery before key long runs or rides.

Professional endurance athletes like Eliud Kipchoge incorporate strength training year-round. If it works for the marathon world record holder, it can work for you too.

Myth 4: High Reps and Low Weight Is the Best Way for Endurance Athletes to Strength Train

The misconception that endurance athletes should always lift lighter weights with higher reps stems from a misunderstanding of strength-building principles. High-rep training builds muscular endurance—but that's already covered in your cardio training.

The Importance of Lifting Heavy

Heavy weights help build:

• Absolute Strength to increase force production.
• Neuromuscular Efficiency to enhance coordination between your brain and muscles.

For endurance athletes, fewer reps (about 4–8) with heavier weights promote overall strength gains without excess fatigue.

Myth 5: You Should Only Strength Train in the Off-Season

Some athletes restrict strength training to off-season periods, believing it should take a back seat once race season starts. While it’s true training volume may need adjustments, completely abandoning strength work can reverse many of the gains you worked for.

How to Adjust for the Season

During race season, shift to lower-frequency strength sessions (1–2 times a week) while maintaining intensity. Short but effective workouts help preserve endurance and strength without interfering with performance.

Myth 6: All Strength Training Exercises Are Beneficial for Endurance Athletes

Not all exercises are created equal. Functional exercises, which mirror demands placed on your muscles during endurance sports, are critical.

What to Focus On

Here are some highly effective strength exercises for endurance athletes:

• Deadlifts for posterior chain strength and injury prevention.
• Single-Leg Squats to address imbalances.
• Plank Variations for core stability.

Avoid non-functional exercises like bicep curls, which might look impressive but provide little value to overall performance.

Myth 7: If You’re Not Sore, You Didn’t Work Hard Enough

Soreness (Delayed Onset Muscle Soreness or DOMS) is not an indicator of productivity. Soreness simply reflects your muscles adapting to new stimuli.

Focus on Consistency, Not Pain

Consistency and progressive overload (gradually increasing weight or difficulty) are far better measures of strength training success than post-workout discomfort. Prioritize proper form and diligent recovery over chasing soreness.
