WHY STRENGTH MATTERS
Why Heavy Resistance Training Matters for Masters Runners
By Greg Kench · 3 min read
Heavy resistance training gives masters runners a stimulus that running alone does not provide: progressively producing high force against external resistance. It can support running economy, maintain strength and contribute to healthy ageing, but it has to be scaled to the athlete.
“Heavy” does not describe one universal percentage or rep range. It means heavy enough for the individual to require high force while keeping the movement controlled and the programme recoverable.
Running fitness and strength are different capacities
A strong aerobic system does not guarantee high force capacity. A runner can complete large weekly mileage and still be a novice with a barbell.
This is why another easy circuit may add work without filling the gap. The aim is not to imitate running indoors. It is to train a capacity that can complement it.
What the running research supports
The evidence is promising, but it is more measured than the loudest fitness claims. A systematic review of 24 distance-running studies reported that running economy often improved by 2-8%, while results were not consistent across every study. Time-trial and sprint outcomes also tended to improve.
A later meta-analysis comparing heavy resistance and plyometric training found small average benefits and suggested heavy resistance work may have a larger effect on running economy. That is a reason to programme it intelligently, not a promise of a specific race result.
Why the case becomes relevant after 40
Ageing changes the context: preserving muscle strength, power and bone health becomes more important. Progressive resistance training is one available tool.
In adults aged 65 and older, a systematic review and meta-analysis found clear improvements in lower-body strength and a smaller, less certain improvement in hip or femur bone mineral density. The evidence does not justify calling lifting a guaranteed shield against osteoporosis or fracture, but it does support resistance training as part of a broader healthy-ageing plan.
General health guidance also recommends muscle-strengthening activity on at least two days a week for adults, while recognising that ability and health status affect what is appropriate.
Heavy does not mean reckless
The sensible route is progressive. Learn the movement, establish a repeatable starting load and add demand when technique and recovery support it.
An athlete new to lifting may get stronger with loads that an experienced lifter would call light. Someone returning after illness, injury or a long lay-off needs a different starting point again. Exercise choice, supervision and progression matter more than proving toughness.
The programme must respect the run calendar
Strength work competes for time and recovery. Long runs, intervals, race proximity, sleep and work stress all change what the runner can absorb.
Two or three weekly sessions appear often in research, but that is not a universal prescription. A useful programme can change frequency and volume across the season. The question is whether the smallest workable dose is still strong enough to produce or maintain the intended adaptation.
What to focus on first
Start by building a few stable movement patterns and tracking the work. Ask whether the load is gradually becoming more demanding, whether the main lifts stay technically controlled and whether the programme leaves room for priority runs.
That is the value of heavy resistance training for masters runners: a clear, measurable strength stimulus placed inside the life and running programme you actually have.
