Adding strength training to your running routine can boost your performance, help fend off injuries, and make every mile feel just a bit easier.
I’ve seen plenty of runners skip strength work, thinking more miles are always the answer. But research—and a lot of real-world experience—shows that runners who hit the weights actually run faster and stay healthier. Balanced muscle strength is key for handling the repetitive pounding of running, especially as you ramp up your mileage or chase a new PB.
In this guide, I’ll break down why strength training matters for runners and share ten essential exercises for the muscle groups that matter most. Whether you’re training for your first 5K or your fifth marathon, these moves will help you get stronger and more resilient—without living in the gym.
10 Strength Training Exercises
Here are ten essential moves that hit the muscle groups runners rely on most. They’ll help you build the kind of strength that shows up on the road and trail.
Squats for Lower-Body Power
I can’t stress enough how important squats are for runners. They build power in your glutes, quads, and hamstrings—the muscles that drive you forward.
Proper squat form:
- Feet hip-width apart, toes slightly out
- Lower down like you’re sitting in a chair
- Keep your chest up and knees tracking over toes
- Go down until your thighs are parallel to the floor
Start with bodyweight squats—2-3 sets of 12-15 reps is a good place to begin. Once you’ve got the hang of it, add weights or try single-leg versions.
Squats mimic the loading your legs take during running, so getting stronger here really does translate to more powerful strides and better hill climbs.
Lunges to Improve Mobility and Balance
Lunges are fantastic because they work one leg at a time—just like running. They target your glutes, quads, and hamstrings, plus they’re great for balance and core stability.
Key lunge variations:
- Forward lunges for basic strength
- Reverse lunges if you want something easier on the knees
- Lateral lunges to open up the hips
- Walking lunges for a bit more challenge
Focus on moving slow and controlled, pushing through your front heel to stand up. Keep your torso upright and watch that your knee doesn’t cave in.
If your knees are a bit dodgy, reverse lunges are a solid choice—they’re easier on the joints but still work the muscles you need.
Step-Ups for Hill Running Strength
Step-ups basically copy the movement of running hills. They build single-leg strength and help you learn to generate power from awkward positions.
Find a sturdy box or bench about knee height. Step up with one foot, push through your heel, and step down with control—no plopping down.
Ways to make step-ups harder:
- Start with just your bodyweight
- Add dumbbells
- Use a weighted vest
- Add a knee drive at the top
Step-ups are great for spotting and fixing strength differences between your legs—pretty important for avoiding injuries. Try 2-3 sets of 8-12 reps per leg, focusing on good form.
Plank Variations for Core Stability
A strong core keeps your running form solid, especially when you’re tired. Planks build those deep ab and back muscles that hold you upright.
Try these plank variations:
- Standard plank (forearms and toes)
- Side plank for lateral core
- Plank with leg lifts for extra challenge
Hold each plank for 30-60 seconds to start, and work up from there. Side planks are especially good for those hard-to-hit side muscles.
And don’t skip Russian twists—they add rotational strength, which helps with arm swing. Sit with knees bent, lean back, and twist your torso side to side.
Single Leg Deadlifts
This move is a real difference-maker. It hits your glutes and hamstrings while challenging your balance—super useful for trail running and keeping injuries at bay.
Stand on one leg, hinge at your hip, and reach down with the opposite hand. Your free leg goes straight back for balance. Stand up by driving your hip forward.
It mimics the single-leg stance of running and builds the muscles that keep you steady. Start with bodyweight, aiming for 6-10 reps per leg. When you’re ready, grab a light dumbbell or kettlebell.
If you deal with IT band issues or knee pain, this one’s especially helpful—it strengthens those stabilising hip muscles.
Upper and Lower Body Essentials
Strength in both your upper and lower body gives you the foundation for efficient running and fewer injuries. These five exercises target the muscle groups that support your posture, arm drive, and overall power.
Press-Ups for Functional Upper-Body Strength
Press-ups are a classic for a reason—they work your chest, shoulders, triceps, and even your core.
Start with standard press-ups on your toes. Keep your body straight from head to heels, lower yourself until your chest nearly touches the ground, and push back up.
Press-up form tips:
- Hands just wider than shoulder-width
- Core locked in
- Move slow and steady
- No sagging hips or sticking your bum in the air
If these are too tough, start with knee or wall press-ups. Once you’re strong enough, try decline press-ups with your feet up.
Aim for 3 sets of 8-12 reps. Don’t worry about huge numbers—good form is what counts.
Pull-Ups to Build Upper-Back and Grip
Pull-ups are tough but worth it. They hit your upper back, shoulders, and grip—helping with posture and reducing tension in your arms and hands.
Assisted pull-ups are a great starting point. Use a resistance band or a machine to lighten the load. Pull your chest up to the bar and squeeze your shoulder blades together.
Pull-up technique:
- Start from a dead hang
- Pull up until your chin clears the bar
- Lower down with control
- Keep your core braced
Can’t do a pull-up yet? Try negatives—jump to the top, then lower yourself slowly. Shoot for 3 sets of 5-8 reps. Even one good pull-up is a win.
Bench Press for Overall Upper-Body Power
Bench press builds upper-body strength that helps with arm drive and stability. It mainly works your chest, shoulders, and triceps, and you’ve got to brace your core too.
Pick a weight you can lift for 8-10 reps with good form. Lie flat, feet on the floor, grip the bar just wider than your shoulders.
Bench press safety:
- Use a spotter or safety bars
- Pinch your shoulder blades together
- Lower the bar slow and steady
- Push up, driving through your feet
No barbell? Dumbbell chest press works too, and it can actually challenge your stabilisers more. Add weight or reps gradually. Aim for 3 sets of 6-10.
Russian Twists for Rotational Core Control
Russian twists build rotational core strength, helping you keep good running form and avoid wasting energy with too much trunk rotation.
Sit with knees bent and feet just off the floor. Lean back until you feel your abs switch on. Hold your hands together and twist from side to side, touching the ground next to your hips.
Start without weight to get the movement right. Keep your chest up, lean back, and try not to let your legs swing around.
To make it tougher:
- Add a medicine ball or dumbbell
- Lift your feet higher
- Slow it down for more control
Go for 3 sets of 20-30 total twists (10-15 each side). Controlled movement matters more than speed here.
Dumbbell Rows
Dumbbell rows target your middle back, rear deltoids, and biceps—key muscles for runners who want to keep their posture upright. They help balance out the hunched shoulders we all get from too much sitting.
I’m a fan of single-arm dumbbell rows since they force each side to pull its own weight and make your core work to keep you steady. Set up with one knee and hand on a bench, grab a dumbbell in your other hand, and row it up toward your hip.
Form fundamentals:
- Keep your back flat and parallel to the floor
- Pull your elbow back, not out to the side
- Squeeze your shoulder blade at the top
- Lower the weight with control
There’s also the bent-over row, where you work both arms at once. It’s a bit tougher on your core and lets you move more weight, if that’s your thing.
Start with 3 sets of 8-12 reps per arm. Pick a weight that’s tough by the last couple reps but doesn’t wreck your form.
Tips for Building an Effective Runner’s Strength Routine
Putting together a good strength routine takes some planning so you don’t end up overdoing it or burning out. Honestly, it’s all about being consistent, letting your body recover, and making sure your lifting fits around your runs—never the other way around.
Benefits for Injury Prevention and Performance
Improved Running Economy: Strength training makes running feel easier at the same pace. Research backs this up—a 12-week strength program can help you use less energy while running at your usual speed.
Your muscles just work better when they’re stronger. You might find yourself running faster without really pushing harder.
Injury Prevention: A lot of running injuries come from muscle imbalances and weakness. Weak glutes? Hello, knee pain. Poor core stability? That messes with your whole running form.
Regular strength work helps fix these weak spots before they turn into bigger problems. Lower-limb resistance training is proven to lower your risk of running injuries.
Enhanced Power and Speed: Stronger muscles mean more force with every stride. You’ll really notice this when you’re powering up hills or sprinting for the finish.
Don’t overlook upper body strength, either. Strong arms and a solid core help you keep good form, especially when you’re tired.
Structuring Sessions for Best Results
Try to keep your strength sessions around 30-45 minutes. That’s plenty to get quality work in without dragging yourself through the mud before your next run. Always start with a 5-10 minute warm-up—think a bit of light cardio and some dynamic stretches to wake things up.
Hit your big compound moves first, like squats or lunges, while you’re still fresh. Save the smaller, isolation stuff for later.
Session Structure:
- Warm-up: 5-10 minutes
- Core exercises: 8-12 minutes
- Lower body compound movements: 10-15 minutes
- Upper body and accessory work: 8-12 minutes
- Cool-down: 5 minutes
Go for 2-3 sets of each exercise, resting 45-90 seconds between sets. You want to challenge yourself but not end up completely wiped out.
If you can, fit strength work on easy run days or rest days. Don’t do heavy lifting before tough runs or long efforts—it’s just not worth the risk.
Progression, Rest, and Recovery
Start simple—bodyweight moves first, then slowly add resistance over 4-6 weeks. Bump up the reps first, then sets, and only then add more weight.
Progressive Loading:
- Weeks 1-2: Nail your form with just bodyweight
- Weeks 3-4: Add light weights or more reps
- Weeks 5-6: Go heavier or make moves more challenging
- Week 7: Ease off for a week—let your body catch up
Give yourself at least 48 hours before working the same muscle group again. Your body needs that downtime to actually get stronger.
Pay attention to how you feel, especially during big running weeks. If you’re dragging, it’s okay to back off the weights or even skip a session.
Recovery’s not just about rest days—it’s also about getting enough sleep (shoot for 7-9 hours) and eating enough protein. Somewhere between 1.2 and 1.6 grams per kilo of body weight daily seems to do the trick for most folks.
Sample Weekly Strength Plan
Here’s my take on a weekly routine that juggles running and strength training without making you want to quit halfway through:
Option A: 2 Days Per Week
- Monday: Easy run + full body strength (about 45 minutes)
- Wednesday: Tempo or interval run
- Friday: Easy run + full body strength (45 minutes again)
- Sunday: Long run
Option B: 3 Days Per Week
- Monday: Easy run + lower body work (30 minutes)
- Tuesday: Easy run + core (20 minutes)
- Thursday: Easy run + upper body (30 minutes)
- Weekend: Long run or just take it easy and rest
When you’re building your base, shoot for three strength sessions a week. As you get closer to race day, it’s fine—actually, smart—to cut back to one or two.
Try to leave at least 4-6 hours between your tough runs and strength workouts if you can swing it. Morning lift, evening jog? Or the other way around. Honestly, whatever fits your life is probably the best plan.
