7 Proven Strength Training Strategies Every Marathon Runner Should Use

[Muscle Madness]

Muscle Madness is here again, and yeah, I know what you're thinking. What’s a weight guy like me doing talking to marathon runners? Simple. I’ve seen too many distance athletes break down mid-season or fall short of their records, not because they lacked heart or mileage, but because they skipped the iron. Strength training for runners is the game-changer nobody tells you about enough.

Let’s get something clear. Lifting isn’t just for bodybuilders and sprinters. It’s essential for marathoners as well. Want fewer injuries, stronger strides, and better running economy? Then strength has to be part of your arsenal. Today, I’m sharing seven proven strategies you can easily incorporate into your marathon prep plan.

Focus on Functional Full-Body Movements​

Let’s kick it off with the foundation. You don’t need fancy machines or isolation moves. You need compound lifts, such as squats, deadlifts, lunges, push-ups, and rows. These are the best exercises for marathon runners because they mimic real-life movement and target multiple muscle groups simultaneously.

The goal? Support your running mechanics. You want your whole body working together efficiently, just like it does during your stride. Prioritize range of motion and movement quality over max weight. You’re training to move better, not just lift heavier.

Build a Strong Core for Better Running Stability​

Runners love talking cadence, mileage, and VO2 max, but your core strength is what keeps you stable and injury-free out there. A strong core reduces energy leaks, maintains solid posture, and protects your spine from the repetitive impacts that can cause injury.

I’m talking planks, anti-rotation moves like Pallof presses, and dynamic core work, such as mountain climbers or medicine ball slams. Your stride will feel smoother, your endurance will improve, and your body will be more efficient from start to finish.

Prioritize Single-Leg Strength​

Here’s the thing. Running is a single-leg sport. You’re never pushing off with both legs at once, so training only with traditional squats won’t cut it. You need to work on unilateral strength.

Add step-ups, Bulgarian split squats, and single-leg Romanian deadlifts into your routine. These exercises build balance, address muscle imbalances, and enhance your push-off power. Stronger single-leg control also lowers your risk of knee and hip issues, especially when you’re deep into your training cycle.

Integrate Strength Work During Base and Build Phases​

You don’t have to lift heavy all year. The key is timing your strength plan for endurance athletes around your marathon calendar. No one has to lift heavy all year long. What matters most is timing your strength plan for endurance athletes in relation to your marathon calendar. Utilize the base phase and early build phase to take on heavier loads and develop genuine strength.

As the miles increase, switch to maintenance mode. Lighter weights, higher reps, and more mobility and activation. It protects your gains in strength without overworking your nervous system before race day. Periodization and smart training can help prevent burnout.

Train the Posterior Chain​

Do you want to know what powers your stride? It’s not your quads but your posterior chain. That includes your glutes, hamstrings, and calves, which the runners consider the holy trinity for marathon power and durability.

Movements like hip thrusts, glute bridges, deadlifts, and calf raises play a key role in building the strength and power runners need during marathon training and should be regular parts of your program. Strengthening your backside not only helps with ground contact and propulsion but also balances out the quad dominance that can result from uphill running or prolonged periods of sitting.

Keep Sessions Short but Effective​

Here’s one of my favorite marathon training tips: your lifting doesn’t need to be long to be effective. In fact, two to three sessions a week, each lasting 30 to 45 minutes, is ideal.

Focus on quality over quantity. Target the key muscle groups, train through a full range of motion, and avoid excessive volume. This approach integrates seamlessly into your training plan without compromising your recovery or performance.

Recover Hard Train Smart

​

Last but not least is recovery. Look, strength workouts are only as good as the recovery that follows. Don’t just log your lifts and ignore the rest. Prioritize sleep, hydration, mobility exercises, and a balanced diet. Your muscles need it, your joints need it, and your next long run depends on it.

Also, space out your lifting sessions from your key runs. Don’t crush deadlifts the day before speed work. Allow your body time to adapt, rebuild, and recover stronger.

Frequently Asked Questions​

How often should marathon runners do strength training?

Ideally, 2 to 3 times per week. During the base phase, you can lift heavier. In peak marathon training weeks, shift to lighter loads and higher reps for maintenance.

What are the best exercises for runners who want to incorporate weightlifting into their routine?

Stick with compound moves like squats, deadlifts, lunges, rows, and core work. Add single-leg movements and posterior chain exercises to support your running mechanics.

When should I stop lifting before race day?

Taper your strength training in the final 2 weeks before race day. Focus on activation, mobility, and light maintenance work only. Save your strength for the course.
