CAN YOU BUILD MUSCLE AFTER 50 AS A CYCLIST?

By Anthony WalshRoadman CyclingUpdated 10 July 2026

ANSWER

Yes. Muscle protein synthesis remains trainable well into your 70s, though the anabolic response to each session is blunted compared with younger athletes — a phenomenon researchers call anabolic resistance. Cyclists over 50 who combine 2-3 resistance sessions per week with 1.6-2.2 g protein per kilogram of bodyweight per day gain measurable lean mass within 8-12 weeks. The key is progressive overload through bodyweight and machine-based movements, not volume on the bike alone.

KEY TAKEAWAYS

Muscle protein synthesis is trainable at any age — anabolic resistance slows the process but does not stop it.
1.6-2.2 g/kg/day protein intake is the evidence-based range for masters athletes building muscle.
Two to three resistance sessions per week with progressive overload drive measurable gains in 8-12 weeks.
Cycling alone does not provide sufficient stimulus to offset age-related muscle loss.

WHO THIS IS FOR

IS THIS YOU?

The rider losing power year on year

You have noticed your sprint and short-climb power declining despite consistent riding, and you suspect muscle loss is the cause.

The over-50 who avoids the gym

You have never done structured strength work and want to know whether it is worth starting at your age.

The weight-conscious cyclist

You worry that building muscle will add kilograms that slow you on climbs.

THE ROADMAN VIEW

Sarcopenia — the gradual loss of muscle mass and function — starts around 30 and accelerates after 50. For cyclists who spend most of their training time in endurance zones, the problem compounds: zone 2 riding does not provide the mechanical tension needed to maintain fast-twitch muscle fibres. You keep your aerobic engine but lose the hardware that produces force.

The fix is not complicated. Two sessions per week of resistance work — leg press, step-ups, single-leg press, Bulgarian split lunges, hip thrusts — with progressive overload changes everything within three months. Pair it with protein timing around those sessions and you reverse the trend.

The muscle you gain is not dead weight. It is functional tissue that protects your joints, maintains bone density, and — critically for cycling — preserves the top-end power you need for short climbs, sprints out of corners, and closing gaps in a group ride.

EXPERT EVIDENCE

WHAT THE EXPERTS SAY

Dr Stuart PhillipsMuscle physiology researcher, McMaster University
Older adults retain the capacity to build muscle, but require a higher per-meal protein dose — approximately 0.4 g/kg per serving — to maximally stimulate muscle protein synthesis. The anabolic resistance of ageing muscle can be partially overcome by leucine-rich protein sources and consistent resistance training.
Dr Keith BaarMolecular exercise physiologist, UC Davis
Collagen synthesis and tendon adaptation take longer in masters athletes. Resistance programmes should include a 12-15 minute warm-up with lighter loads to prime connective tissue before heavier work, and progression should occur over weeks rather than days.

PRACTICAL APPLICATION

DO THIS WEEK

Start with two resistance sessions per week
Focus on compound movements: leg press, step-ups, Bulgarian split lunges, hip thrusts, and calf raises. Three sets of 8-12 reps per exercise. Progress the load by 2-5% when you can complete all sets with good form.
Hit 1.6 g/kg protein per day minimum
Spread across 4 meals of roughly equal protein content. Include a 30-40 g serving within two hours of resistance training. Leucine-rich sources — whey, eggs, chicken, Greek yoghurt — are most effective at overcoming anabolic resistance.
Separate hard rides from strength days
Heavy endurance work blunts the anabolic signal from resistance training. Where possible, place strength sessions on easy ride days or rest days. If you must double up, do strength first and ride easy afterwards.
Track lean mass, not just bodyweight
Use a DEXA scan or bioimpedance scale at baseline and again at 12 weeks. Bodyweight alone does not tell you whether you have gained muscle or lost it — body composition is the metric that matters.

COMMON MISTAKES

WHAT CYCLISTS GET WRONG

MISTAKERelying on cycling volume alone to preserve muscle.
FIXEndurance riding maintains slow-twitch fibres but does not load fast-twitch fibres enough to prevent atrophy. Resistance training is non-negotiable after 50.
MISTAKEEating too little protein because of calorie concerns.
FIXUndereating protein accelerates sarcopenia. Prioritise 1.6-2.2 g/kg/day and adjust carbohydrate intake to manage total calories if needed.
MISTAKEUsing light weights with high reps exclusively.
FIXWhile lighter loads can build muscle if taken close to failure, moderate loads (60-80% of 1RM) are more time-efficient and produce stronger anabolic signalling in older adults.

FAQ

FREQUENTLY ASKED QUESTIONS

Will gaining muscle make me slower uphill?

Functional muscle improves your power-to-weight ratio if the gains come with corresponding strength increases. A rider who gains 2 kg of lean mass but adds 20W to their threshold power is faster on every gradient.

How long before I see results?

Strength gains from neural adaptations appear within 3-4 weeks. Visible muscle growth typically takes 8-12 weeks with consistent training and adequate protein.

Can I build muscle without a gym?

Yes. Bodyweight exercises — pistol squats, step-ups on a high box, single-leg Romanian deadlifts, wall sits — provide sufficient stimulus when performed with progressive overload through range of motion or tempo.

Is creatine safe for over-50s?

Creatine monohydrate (3-5 g/day) is one of the most studied supplements in sports science and has a strong safety profile in older adults. Research by Candow et al. shows it enhances lean mass gains when combined with resistance training in people over 50.

Does testosterone decline affect muscle building?

Testosterone drops roughly 1-2% per year after 30, which contributes to anabolic resistance. However, resistance training itself raises acute testosterone and growth hormone levels, partially offsetting the decline. The training stimulus matters more than baseline hormone levels.

Should I take BCAAs?

If your total daily protein intake is adequate (1.6-2.2 g/kg), BCAAs offer no additional benefit. Whole protein sources containing all essential amino acids are more effective and cheaper.
