In the world of MTB – and more generally of endurance disciplines – one of the most recurring questions concerns the role of strength training: Is it really necessary? And how should it change as we age?
The doubt comes above all from two categories of athletes:
- Parents of young bikers, rightly concerned with preserving the physical development of growing athletes.
- Over 40, which begin to confront the natural decline in muscle strength.
The answer is complex and depends on your age, training level, and goals.
Strength in young people: when and how to start
In boys the introduction of strength training must be progressive, calibrated and supervised, always taking into account physical development and the discipline practiced.
Debutant
At this stage we are talking more about movement education:
- free body exercises
- coordination
- mobility sectors
- strength games
The goal is not to “move loads,” but to correctly learn basic movement patterns: push-ups, squats, pull-ups, lunges.
Raw little cuttlefish
When the body is more structured you can start:
- to gradually increase the load
- to work with elastic bands or light weights
- to introduce controlled multi-joint exercises
Always with reduced volumes and absolute attention to technique.
Junior
Only here does the structured “cast iron”:
- programmable gym sessions
- strength periodizations
- progressive loads
All adapted to the specialty: XC, marathon, enduro or DH will require different stimuli.
And in the Silver Age?
The situation is almost mirror-image.
If the athlete has a history of continuous training:
- the muscle structure will be relatively stable
- the main work will be to maintenance
With age, in fact:
- strength tends to decrease naturally
- aerobic endurance can be maintained for longer
For this reason it is advisable to:
- slightly reduce some pure endurance sessions
- integration 2 strength sessions per week
- work on maximal stimuli and essential strength
The goal is maintain power, neuromuscular efficiency and responsiveness, all fundamental qualities even in endurance races.
Strength or resistant strength?
From a methodological point of view, the answer is clear:
👉 You need to train pure STRENGTH.
Resistant force can only be used in specific cases:
- work on core
- preparazione DH and Enduro
- HIIT, Tabata and circuit protocols to simulate the intensity of a run
But for most bikers – especially XC and marathon – the focus remains on maximum strength.
Why isn't the bike enough?
There's a common misconception: Strength/Resistance Climbs (SFRs) seem to replace the gym. In reality:
A single repetition of SFR (4' at 50 rpm) is approximately equivalent to:
- 100 squats per leg
- with 4–5 repetitions → 400–500 total reps
Let's talk about hard work, with sub-maximal load, not real strength.
In the gym instead
- we can work with heavy loads
- check execution and progressions
- stimulate neuromuscular recruitment
- improve the ability to express power
It is precisely this type of stimulus that:
- improve it sprint start
- makes it more effective in changes of pace
- allows the muscle to bear greater loads even in the saddle
The true role of strength in endurance biking
Strength training:
- it does not help to increase body weight
- it's not bodybuilding
- enhances the overall efficiency of the gesture
More strength means:
- better pedaling economy
- greater joint stability
- reduction of injury risk
- better ability to handle high intensities
Conclusions
✅ Young bikers
- Yes to cast iron, but with caution, progressiveness and technique
- The load arrives only in the junior stage
✅ Silver Age
- More strength than ever before
- Less aerobic volume, more muscle maintenance sessions
👉 At every stage of life:
Strength remains the ability that can be trained least directly on the bike and the one that most influences overall performance.
