Strength training for masters runners: How-to-guide for your 40s, 50s, 60s and beyond

By Henry Howard

For many runners in their 40s, 50s, 60s and beyond, recovery takes longer, injuries linger, and that effortless speed you once had requires more work to maintain. This is the reality of masters running, but here’s the good news: it doesn’t have to be a story of an inevitable sharp decline.

With smart training, particularly strength training, you can continue running strong, racing competitively and setting new goals as you age.

This strength training for masters runners guide is the final installment of a special four-part series. The first part covered why strength training is essential for runners, how to incorporate it into your routine, and the best upper body exercises to improve performance and prevent injury. Part 2 focused on the best strength training options for ultra runners. And Part 3 offered advice to women runners throughout various life stages.

(Thanks to my friends at AmazFit for their support of this series. I recently tried the AmazFit T-Rex 3 Pro watch and honestly found that it is a better option than Coros and Garmin.

Why strength training is critical for aging runners

As we age, our bodies undergo physiological changes that directly impact running performance. Starting around age 30, we lose about 3-8% of muscle mass per decade, a process called sarcopenia that accelerates after age 60.

Our bone density decreases, particularly in women after menopause. Tendon elasticity diminishes. Connective tissue becomes less resilient. Hormone levels shift, affecting everything from recovery to body composition.

These changes aren’t purely cosmetic or abstract, they directly affect your running. Less muscle mass means less power and slower speeds. Decreased bone density increases fracture risk. Stiffer tendons store and release less energy with each stride. Reduced connective tissue resilience makes you more injury-prone.

But this is where strength training changes the game.

Research consistently shows that resistance training can slow, halt, or even partially reverse many age-related declines. Studies on masters athletes demonstrate that those who strength train maintain muscle mass, bone density and power output far better than those who only run. Research shows that well-trained 60-year-olds can have the muscle function of sedentary 30-year-olds.

Perhaps most importantly, strength training addresses the root cause of most masters running injuries: decreased tissue capacity to handle load. When you run, your body experiences forces of 2-3 times your body weight with every step. If your muscles, tendons and bones can’t handle that load thousands of times per run, something eventually fails. Strength training builds that capacity back up.

As a masters runner, my strength training has generally been with bodyweight exercises. Those include almost daily pushups, core work and some specific leg-strengthening routines post-run four or five times a week. But recently I have started working with weights.

For masters athletes, there is no one-size-fits-all method for strength training. What follows is a general guideline, which I would adapt to an athlete, based on their fitness level, goals and other criteria. If you are considering starting a strength training routine, consult with a medical professional first and be sure to focus on form over reps or weights.

Strength training tips across the masters spectrum

The recreational jogger: Staying healthy and active

If you’re running a few times per week for health, stress relief, and enjoyment rather than competition, your strength training should focus on maintaining functional capacity and preventing injury.

Your goals are straightforward: maintain muscle mass, keep your bones strong, preserve the ability to move well, and prevent the common injuries that sideline casual runners. You’re not chasing PRs, but you want to keep running for decades to come.

Two 30-minute strength sessions per week are perfect. Focus on full-body movements that build practical strength. You don’t need to lift extremely heavy; moderate weights with good form will serve you well.

Essential exercises:

• Goblet squats: Maintains leg strength and mobility. Do 3 sets of 10-15 reps.

• Pushups: Builds upper body strength. Modify on knees if needed. I generally don’t prescribe set and numbers for pushups because I don’t want to make them too easy or too hard for my athletes. Instead, aim for a consistent number from set to set, going to about 80-85% of your max on the first set. After a brief break, do the same number. And build up the number of reps and sets as you get stronger.

• Dumbbell rows: Strengthens back and posture. Complete 3 sets of 10-12 reps per side.

• Glute bridges: Hip strength is crucial for healthy running. Do 3 sets of 15-20 reps.

• Planks: Core stability protects your back. Hold 3 sets of 30-45 seconds, increasing up to a minute as you get stronger.

• Calf raises: Prevents Achilles issues. Perform 3 sets of 10-20 reps.

The competitive masters marathoner: Balancing speed and resilience

You’re still chasing times, still lining up for races, still pushing yourself to see what you’re capable of at this stage of life. Your strength training needs to support performance while protecting against the increased injury risk that comes with higher mileage and intensity.

Your challenge is balancing high running volume with adequate strength work. You can’t afford to be too fatigued from the gym to run well, but you also can’t afford to skip strength work and risk injury.

Focus on exercises that directly support running performance: power development for maintaining speed, eccentric strength for downhill running and injury prevention, and single-leg stability for efficient movement patterns.

Essential exercises:

• Bulgarian split squats: Single-leg strength is crucial. Hold dumbbells for added resistance. Do 3 sets of 10-12 reps per leg.

• Romanian deadlifts: Builds posterior chain strength essential for powerful running. Perform 3 sets of 8-10 reps with challenging weight.

• Stair steps: Functional strength with carry-over to running. Complete 2 sets of 20 to 30 reps per leg.

• Nordic hamstring curls: The gold standard for hamstring injury prevention. Start with 3 sets of 5 reps, building slowly.

• Single-leg deadlifts: Balance and posterior chain strength combined. Do 3 sets of 10 reps per leg.

• Medicine ball overhead throws: Power development for maintaining speed. Perform 3 sets of 8-10 reps.

• Lateral band walks: Hip strength and stability. Complete 2 sets of 20 steps per direction: left, right, forward and backward.

  
  

Masters ultra runners: Building durability for the long game

Running ultras in your 40s, 50s, 60s, or beyond requires a different kind of toughness. You’re not necessarily chasing speed. You are building the durability to spend hours on mountain trails, to climb thousands of feet, and to descend technical terrain without destroying your legs.

Your strength training should emphasize muscular endurance, eccentric strength for downhill running, and stability for navigating technical terrain when fatigued. You also need to be strategic about recovery, as ultra training volume alone is demanding.

Essential exercises:

• High-rep squats: Bodyweight or light weight, 20-25 reps. Builds muscular endurance. Do 3 sets.

• Eccentric step-downs: Step down from a box, controlling the descent slowly. Protects quads on downhills. Perform 3 sets of 12-15 reps per leg.

• Walking lunges: Functional endurance and strength. Complete 3 sets of 20 total steps.

• Single-leg box touches: Balance and strength when fatigued. Do 3 sets of 15 reps per leg.

• Farmer carries: Holds dumbbells and walks. Builds grip, core, and real-world strength. Perform 3 sets of 40-60 seconds.

• Dead bugs: Core stability for long days on the trail. Complete 3 sets of 12 reps per side.

• Calf raises: Single-leg variations for ankle strength and stability. Do 3 sets of 20 reps per leg.

During ultra training blocks, reduce strength volume but maintain frequency. Two 20-30 minute sessions beat one 60-minute session that leaves you too fatigued to run well the next day.

Universal principles for masters strength training

• Warm up thoroughly. Cold muscles and stiff joints are asking for injury. Spend 5-10 minutes on dynamic stretches and movement prep before lifting.
  

• Prioritize form over weight. Sloppy form with heavy weight is how masters athletes get injured. Perfect your technique with lighter loads, then progress gradually.
  

• Recover appropriately. You can’t recover like you did at 25. Build in rest days. Sleep 7-9 hours. Eat adequate protein (1.6-2.0g per kg body weight). Consider taking an extra day between hard sessions if needed.
  

• Focus on injury prevention. Include exercises that address your personal weak points. If you’ve had IT band issues, prioritize hip strengthening. If Achilles tendinopathy is your nemesis, eccentric calf work is essential.
  

• Lift heavier than you think. Many masters athletes stay too conservative with weights. To build strength and bone density, you need to challenge yourself. If you can do 15 easy reps, the weight is too light. Aim for weights where the last 2-3 reps of a set are genuinely difficult.
  

• Stay consistent year-round. Don’t abandon strength work during racing season or take months off. Consistency builds resilience. Even maintenance sessions during peak training are valuable.

  
  

• Listen to your body, but distinguish between discomfort and pain. Muscle burn during exercise is normal. Sharp pain, joint pain, or pain that worsens during a set is a warning sign. Stop and assess.

What masters athletes should know about strength training

The beauty of masters running is perspective. You’ve learned that running is a lifelong journey, not a sprint. You understand that health and longevity matter more than any single race result. You know that consistency beats intensity.

Strength training embodies this same wisdom. It’s not about how much you can lift this week, it’s about building a body that can run strong next month, next year, and next decade. It’s about respecting the physiological changes of aging while refusing to accept unnecessary decline.

Every strength session is a declaration that you are not done yet. You’re not winding down. You’re adapting, evolving, and continuing to pursue this sport you love with intelligence and determination.

Your fastest days might be behind you, but your strongest days can still be ahead. The runner you are at 50, 60, or 70 can be more resilient, more capable, and more complete than the runner you were at 30. Strength training is how you make that happen.

Keep running. Keep lifting. Keep showing up. Your future running self will thank you.

Frequently Asked Questions: Strength training for masters athletes

Q: I’m 58 and have never lifted weights. Is it safe to start now? A: Yes, but start smart. Consider working with a qualified trainer for your first few sessions to learn proper form. Begin with bodyweight exercises and light weights, focusing on technique. Get medical clearance if you have any health concerns. Research consistently shows that people in their 60s, 70s and beyond can safely build strength with proper progression.

Q: How heavy should masters athletes lift? A: Heavy enough to challenge yourself. To build strength, you should reach muscular fatigue (where the last 2-3 reps are difficult) within 6-10 repetitions. This typically means lifting at 70-85% of your one-rep max. That said, perfect form always takes priority over weight. If your form breaks down, the weight is too heavy.

Q: My recovery takes much longer than it used to. How should I adjust my training? A: Allow more time between hard sessions, both running and lifting. Consider 48 to 72 hours between intense strength sessions instead of 24 to 48 hours. Two quality sessions per week on the same days as your two hardest running efforts is highly recommended. Easy days easy, hard days hard. Prioritize sleep, nutrition and active recovery. If you’re consistently overly fatigued, reduce volume or intensity.

Q: Should I strength train differently if I’m dealing with chronic injuries? A: Yes. Work with a physical therapist to identify movement dysfunctions and address them through targeted exercises. Often, chronic injuries stem from weakness or imbalance elsewhere in the kinetic chain. For example, knee pain might require hip strengthening. Continue strength training but avoid exercises that aggravate your injury until it’s resolved.

Q: Is it better to do more frequent, shorter sessions or fewer longer sessions? A: For most masters athletes, two 30-45 minute sessions per week is ideal. This provides sufficient stimulus without excessive fatigue. If schedule constraints make this difficult, two 20-minute sessions are better than nothing. Consistency matters more than session length.

Q: Can strength training actually reverse age-related muscle loss? A: Yes, to a significant degree. Research shows that resistance training can increase muscle mass even in adults in their 70s, 80s and 90s. While you may not rebuild to your 25-year-old levels, you can maintain or regain substantial muscle mass and function with consistent, progressive strength training.
