Oly BockThree ready gym sessions with sets, reps and rest, for the time you actually have. Written 29 October 2026.
Short answer: With 15 minutes, do Bulgarian split squats, Romanian deadlifts and bent-knee calf raises, two sets each. With 30 minutes, add heavy squats, step-ups and a dead bug. With 45 minutes, build the session around deadlifts, hip thrusts, Copenhagen planks and chin-ups. Each session covers what runners need most, so even the short one pays into your running.
Your running week moved again. The long run slid to Sunday, a call ate your lunch break, and the strength hour you planned now has 30 minutes, or 15. Keeping the session anyway is the right call: a short session done this week keeps your legs ready for the next hard run.
I’m building an iPhone app for exactly this moment; there’s a short note on it near the end.
The 30-minute session below is the one I’d pick on a day like that.
Every session here covers what runners need most
Running is a long series of single-leg landings, and the back of the legs and the calves work on every stride. All three sessions start from there; the longer ones add a heavy two-leg lift, core and upper body.
The minutes include a short warm-up and the rest times in the tables. Set a timer for the rests, and the session ends on time.
For every set, pick a weight where the last two reps are hard and your form still holds. That’s heavy enough to build strength and light enough for your next run.
The 15-minute session still counts as a full strength day
| Exercise | Sets × reps | Rest | Cue |
|---|---|---|---|
| Bodyweight squat (warm-up) | 1 × 10 | – | Slow down, fast up |
| Bulgarian split squat | 2 × 8 per side | 60 s | Weaker side first. Front knee over the toes. Rear foot on a bench. |
| Romanian deadlift | 2 × 8 | 60 s | Flat shoes or barefoot |
| Calf raise, bent knee | 2 × 15 | 30 s | Bent knee works the soleus. Lower slowly. |
Runners use the split squat for a stronger push-off on hills, the Romanian deadlift for the hamstrings and glutes, and the bent-knee calf raise for the deeper calf muscle that works on every stride.
This is the session for a packed day. Three moves, two sets each, and you leave the gym with a real strength day in your log.
The 30-minute session adds heavy squats for stronger legs on hills
| Exercise | Sets × reps | Rest | Cue |
|---|---|---|---|
| Hip hinge drill (warm-up) | 1 × 10 | – | Stick along the spine, push the hips back |
| Bodyweight squat (warm-up) | 1 × 10 | – | Slow down, fast up |
| Squat | 3 × 5 | 2 min | Build to a weight you could lift about 7 times |
| Single-leg RDL | 3 × 8 per side | 60 s | Weaker side sets the reps |
| Step-up | 2 × 10 per side | 60 s | Drive through the whole foot on the step. Lower slowly. |
| Calf raise, straight knee | 3 × 12 | 30 s | Full range, lower slowly |
| Dead bug | 2 × 8 per side | 30 s | Lower back stays down |
The squat is the heavy lift of the session. The single-leg RDL and the step-up train balance and strength on one leg, the way you load it on every stride. The dead bug comes last: runners use it to stay steadier late in a long run, when form starts to drift.
The 45-minute session builds the strongest legs and adds chin-ups for upright posture
| Exercise | Sets × reps | Rest | Cue |
|---|---|---|---|
| Hip hinge drill (warm-up) | 1 × 10 | – | Stick along the spine, push the hips back |
| Banded lateral walk (warm-up) | 1 × 12 steps per side | – | Band above the knees, stay low. Toes forward. |
| Deadlift | 3 × 5 | 2–3 min | Build to a weight you could lift about 7 times |
| Bulgarian split squat | 3 × 8 per side | 90 s | Weaker side first. Front knee over the toes. |
| Hip thrust | 3 × 10 | 60 s | Chin tucked, ribs down. Shins vertical at the top. |
| Seated leg curl | 2 × 12 | 60 s | Pad just above the heels |
| Calf raise, bent knee | 3 × 15 | – | Lower slowly |
| Copenhagen plank | 2 × 20 s per side | – | Adductors, short range first |
| Chin-ups | 3 × 5–8 | 90 s | Palms facing you, shoulder-width grip |
To stay inside 45 minutes, do the last three as a circuit: calf raises, Copenhagen plank, chin-ups, then rest 90 seconds and go again.
The deadlift and hip thrust give you the most strength for hills and the last kilometres of a long run. The Copenhagen plank works the inner thigh, which runners use to feel steadier on uneven ground. Chin-ups train the upper back that holds you upright when you tire.
Away from the gym, the same sessions work with small swaps
Every move above has a home or travel version. A Bulgarian split squat works with the rear foot on the sofa or the bed, a Romanian deadlift works with one pair of dumbbells, and step-ups work on the stairs. Your week stays on track wherever you are.
Pick the length that fits the day: any of the three counts as a strength day.
An app that gives you a session for the time you have
Disclosure: I’m building this app.
It’s an iPhone app for runners who lift. 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 week, a short session still counts, and every session pays into your running. The app is coming soon to the App Store.

FAQ
Is a 30-minute strength workout enough for runners?
For most runners who lift, yes. Thirty minutes covers a heavy lift, two single-leg moves, calves and core, which is a complete session. Done regularly, short sessions add up over a training block.
What if I only have 20 minutes?
Do the 15-minute session and use the extra five minutes for a slower warm-up and a third set of split squats. You keep all three moves and gain one more hard set.
How often should runners do strength workouts?
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). Mixing lengths works well: a 45 on a quiet day, a 15 when the week fills up.
Can I do these workouts without a gym?
Yes, with small swaps. Put the rear foot on the sofa for split squats, use one pair of dumbbells for Romanian deadlifts and step up onto the stairs.
How heavy should I go?
Pick a weight where the last two reps of each set are hard and your form holds. On the squat and deadlift, that means a weight you could lift about seven times for a set of five.
How I put these sessions together
- Exercises and form cues: taken from the exercise list of the strength app I’m building for runners, as of 29 October 2026.
- Sets, reps and rest: the rep ranges follow the American College of Sports Medicine position stand Progression Models in Resistance Training for Healthy Adults (2009): heavy sets of five for the main lift, 8–12 reps for most other moves, higher reps with short rests for calves. The position stand lists 3–5 minutes of rest for heavy sets; the sessions here use 2–3 minutes to stay on time, so add a minute if you have it.
- Minutes: counted at about 40 seconds per set plus the listed rests and about 15 seconds per change of exercise, the sessions come to roughly 12, 29 and 41 minutes. The rest of the time goes to setting up and loading the bar.
