Oly BockA guide for runners who lift or want to start. Three studies, the WHO guideline and nine public runner threads read, checked 30 October 2026.
Short answer: Two strength sessions a week cover what most runners need. Build each one from five patterns: a squat, a hinge, a single-leg move, calf work and core. In 15 minutes, do one round of the biggest moves; in 30, add sets; in 45, add load and upper body. The same patterns work at the gym, at home or in a hotel room.
You already know strength work would help your running. The hard part is the week itself: a long day at work, a run that took longer than planned, a hotel room with a carpet and a chair. So the session gets pushed to tomorrow, and tomorrow fills up too. Wanting a plan that survives a busy week is the right instinct, because consistency is what pays off in your running.
This guide gives you that plan: what to do with 15, 30 or 45 minutes, wherever you are, and where to put it around your runs. I’m building a strength app for runners with exactly this problem; more on that near the end.
Two sessions a week cover what most runners need
The World Health Organization recommends muscle-strengthening activities that work all major muscle groups on two or more days a week for adults (WHO guidelines on physical activity and sedentary behaviour, 2020). For runners, a 2018 systematic review of 24 studies on middle- and long-distance runners concluded that two to three strength sessions a week are likely to benefit running performance (Blagrove, Howatson and Hayes, Sports Medicine, 2018).
One session a week still counts. Across the public runner threads I read (r/AdvancedRunning, r/running, r/runninglifestyle, r/trailrunning, read 28–29 October 2026), the same story repeats: runners who kept one short session going for months got more out of it than runners who planned three and dropped all of them by February. Some strong runners lift little or not at all, and they say so openly. If you’ve decided to lift, the regular habit is what makes the difference.
Five movement patterns carry most of the work
Runners argue about exercises endlessly, yet the lists in coaching books and runner threads converge on the same five patterns. Pick one exercise from each and you have a complete session.
| Pattern | What runners use it for | Gym | Home or hotel |
|---|---|---|---|
| Squat | Stronger legs for hills and the last kilometers | Squat, step-up | Bodyweight squat, single-leg box squat |
| Hinge | Hamstrings and glutes for a stronger push-off | Romanian deadlift, deadlift | Single-leg RDL, single-leg glute bridge, hamstring walkout |
| Single leg | Steadier on one leg, which is how you run | Bulgarian split squat | Reverse lunge, step-down |
| Calves and feet | Springier calves for faster running and longer runs | Calf raise, straight and bent knee | Calf raise on a step, tib raise |
| Core | Holding your posture late in a long run | Pallof press, Copenhagen plank | Side plank, dead bug, bird dog |
Upper body is a useful sixth pattern if you have time. Push-ups, inverted rows or chin-ups help many runners keep their arm swing and posture steady late in a run. Runners in the threads mention it often, usually as the part they add once the legs are covered.
Heavier strength work is linked to better running economy
Running economy is how much energy you use at a given pace. Better economy means the same pace feels easier. A meta-analysis of controlled trials in highly trained runners found that adding strength training over several weeks improved running economy (Balsalobre-Fernández, Santos-Concejero and Grivas, Journal of Strength and Conditioning Research, 2016). A 40-week study in distance runners found gains in maximal strength and running economy with no change in body composition (Beattie and colleagues, Journal of Strength and Conditioning Research, 2017).
Most of these studies used real loads, with several sets of a few hard reps and some jumping work. That’s why bands and light weights get you started, and heavier sets, once your form is solid, give you more for your running.
New to lifting? Start with bodyweight and two short sessions
If you’ve never lifted, start with your own body weight and two sessions of 15 to 20 minutes a week. Six moves cover all five patterns: bodyweight squat, single-leg glute bridge (start on two legs if one feels shaky), step-up, calf raise, dead bug and side plank.
Do two sets of each and stop every set while two more clean reps would still be possible. That’s enough to get stronger in the first weeks and leaves your legs ready for your next run. Expect some sore legs after the first sessions; it fades as you repeat them, so put those early sessions after an easy run or on a rest day, well away from your hardest run of the week.
Once two sets feel easy, move on in this order: a third set, then single-leg versions, then a pair of dumbbells. When the 15-minute session below feels routine, the 30-minute session is your next step.
15 minutes still counts when you pick the biggest moves
You rarely get the session you planned. Here is how the same five patterns scale with the time you have.
15 minutes: one round of the essentials. Two quick warm-up sets, then two sets each of a squat or single-leg move, a hinge and calf raises, done as a circuit. Finish with one side plank per side. You leave a little fresher than after a hard run, and the habit stays alive.
30 minutes: the full session. A five-minute warm-up, then three sets each of a squat, a hinge, a single-leg move and calves. Pair the calf work with a core exercise to save time. This is the session to aim for twice a week.
45 minutes: add load and upper body. Same structure, with one heavy main lift first (squat or deadlift), then the single-leg and calf work, then a push and a pull for the upper body. Add a few short jumps at the start if they suit your week.
Ready-made versions of all three, with sets and reps, are in 15-, 30- and 45-minute strength workouts for runners.
The same plan works at the gym, at home or in a hotel
Where you train changes the exercises, and the patterns stay the same.
At the gym you can load the main lifts, which is the most time-efficient way to get stronger. A barbell or dumbbells for the squat and hinge, a step or bench for single-leg work, a calf raise machine or a plate under your toes.
At home, one pair of adjustable dumbbells or a single kettlebell covers almost everything. Runners in the threads who train at home often build a whole year around a kettlebell, a few bands and a step. Single-leg work makes light weights feel heavy fast, which is exactly what you want when the weights are limited.
In a hotel, use the room or the small hotel gym. A chair for Bulgarian split squats and step-downs, the bed edge for single-leg glute bridges, a towel on the floor for slider leg curls, and the stairs for calf raises. Twenty-five minutes in a hotel room is a real session.
Heavy legs fit best next to your hardest runs
Where strength sits in your week matters as much as what you do. Many coaches and experienced runners stack heavy leg work on the same day as a hard run: intervals in the morning, legs in the evening, an easy day after. Your easy days stay easy, and the day before a key run stays free of heavy legs.
Upper body and core fit almost anywhere, because they leave your running legs fresh.
Strength training through a marathon build keeps the same moves and changes the dose
A marathon build adds long runs and weekly kilometers, so strength work has to fit around them. The exercises stay the same through the whole build. What changes is how much you do.
- Early in the build, running volume is still moderate. This is where two full sessions a week fit best and where you can lift your heaviest.
- In the middle, as the long runs grow, keep two sessions if they fit, or one full session plus a 15-minute one. Heavy legs go on the day of a hard workout, never on the day before your long run.
- In the racing season and the last weeks before a race, keep the movements and cut the sets. The 2018 review cites a study in which runners went from two strength sessions a week in preparation to one during the racing period, and kept the strength and fitness they had built (Blagrove, Howatson and Hayes, 2018).
The same logic works for a half marathon, with a shorter build.
Warm-ups, core, jumps and stretches fill the gaps between sessions
Four short pieces fit around your runs, without a gym session of their own:
- A running warm-up before intervals and races: a few minutes of drills and strides get you to the first rep ready to run.
- A short core routine on easy days, ten minutes on the floor.
- Plyometrics, a few sets of short jumps such as pogo hops, ideally before a strength session or after an easy run.
- Stretches after the run, ten minutes for calves, hamstrings, quads and hips.
Lift a little more over the months, and lighter near races
Strength comes from doing a bit more over time: a few more reps, then a little more weight, with the last rep of each set still clean. Runners in the threads who kept progressing usually did it slowly and paired it with their running calendar, building in quieter running weeks and holding steady in the busiest ones.
Close to a race, most runners keep lifting with less volume. Fewer sets of the same movements keep the strength you built and leave your legs fresh for race day.
If you want to see that progress, a training log helps. Two popular ones are compared in Hevy vs Strong.
A strength app that fits your running week
Disclosure: I’m building this app.
It’s an iPhone app for runners who lift or want to start. Say how much time you have and where you are, and you get the right session for your running. I logged 101 gym sessions in Strong and liked it, but nothing in it was built around a running week: the time I have, where I am and which days I run. So I’m building that app myself.
It fits around your runs, a short session still counts, and every session pays into your running. The app is coming soon to the App Store; what it does and who it’s for.

FAQ
How often should runners strength train?
Two sessions a week suit most runners. A 2018 review of 24 studies on distance runners found two to three sessions a week likely to benefit running performance (Blagrove and colleagues, 2018). One focused session of 15 to 30 minutes still keeps the habit going in a busy week.
Should I lift before or after a run?
If the run is the key session of the day, run first and lift later, ideally with a few hours in between. After an easy run, a short strength session straight away works well.
What kind of strength training should runners do?
Cover five patterns: a squat, a hinge, a single-leg move, calf work and core. Start with body weight or light loads, then move to heavier sets of a few reps once your form is solid, because most studies that linked strength work to better running economy used real loads.
Is Pilates enough strength training for runners?
Pilates trains core control and mobility, and many runners enjoy it. The studies on running economy mostly used heavier leg work, so Pilates fits best next to one leg session a week rather than in place of it.
Will lifting make me heavier or slower?
In a 40-week study of distance runners, strength training improved strength and running economy with no change in body composition (Beattie and colleagues, 2017). Runners in the threads who lift twice a week alongside their running describe the same: stronger legs, similar weight.
Do I need a gym?
You can start at home. A pair of dumbbells or a kettlebell, a step and some floor space cover all five patterns. A gym makes heavier loads easier later, which helps once home weights feel light.
Can I keep lifting during marathon training?
Yes. Most runners keep lifting through a build, with heavier work early on and fewer sets as the race gets close. Keep heavy legs away from the day before your long run; the full outline is in the marathon section above.
