SHOULD CYCLISTS LIFT HEAVY OR LIGHT?

WHO THIS IS FOR

IS THIS YOU?

The cyclist doing high-rep band circuits

You're working hard but the exercises feel easy — and you're probably not getting the adaptation you need.

The rider nervous about lifting heavy

You worry about injury but want to understand what 'heavy' actually means for a cyclist's programme.

THE ROADMAN VIEW

The Roadman view

There's a version of 'strength training for cyclists' that's really just stretching with weights — fifteen reps of a light goblet squat, some band work, a few core exercises. It feels productive, it takes 40 minutes, and it doesn't move the needle. Anthony has been in this conversation with Derek Teel more than once, and the answer is consistent: that kind of work is adding endurance volume you already have from riding.

The adaptation that cyclists are missing is maximal strength and the ability to recruit a high proportion of motor units on demand. That comes from working with heavier loads. You don't need to get anywhere near your 1RM — the goal is 4–8 reps at a weight where the last two require real focus and controlled form, not 20 reps that feel like a warm-up.

The shift in thinking is from 'muscular endurance, which I already have' to 'strength quality, which I'm missing'. That shift changes the exercise selection, the loads, and the results. Cyclists who make this switch typically see more transfer to the bike in 8 weeks than they got from 6 months of light circuit work.

EXPERT EVIDENCE

WHAT THE EXPERTS SAY

  • Derek TeelStrength coach for cyclists (Dialed Health)

    Cyclists often default to high-rep, light-load work because it feels less intimidating and mirrors what they know from riding. But that's exactly the adaptation they don't need more of. Heavier loading at lower reps trains the neuromuscular system to recruit more muscle and produce force — which is what creates the bike-strength transfer.

    Fast-twitch fibre loss begins around age 35 and accelerates with each decade. The specific stimulus that recruits and preserves fast-twitch fibres is high-load, lower-rep training. Endurance training does not provide this stimulus — it has to come from the gym, at meaningful loads.

PRACTICAL APPLICATION

DO THIS WEEK

  1. Find your working weight on each exercise

    For your first session, choose a weight where you can do 10 reps cleanly, then add 10–15%. That's roughly your 6–8 rep working weight. Use this as your starting load and record it.

  2. Work in 4–6 rep sets for primary lifts, 6–10 for accessories

    Primary movements — split squat, Romanian deadlift — deserve the lower rep, higher-load treatment. Accessory work — rows, presses, core — can sit in the 6–10 range. Both are heavier than most cyclists start.

  3. Add 2.5–5kg to lower body and 1–2.5kg to upper body every 1–2 weeks

    Progressive overload is what turns gym sessions into strength gains. If the weight doesn't change over 6 weeks, you're maintaining, not progressing. Keep a log.

COMMON MISTAKES

WHAT CYCLISTS GET WRONG

  • MISTAKEUsing 15–20 rep sets and calling it strength training.

    FIXThat's muscular endurance training. Switch to 4–8 rep sets with heavier loading to target the neuromuscular adaptations cycling doesn't provide.

  • MISTAKENever adding weight to the bar over months of training.

    FIXProgressive overload is the mechanism. Track your loads and increase them regularly. Comfort with the same weight means you've stopped adapting.

  • MISTAKEEquating 'heavy' with 'reckless'.

    FIXHeavy means the last 2 reps are challenging with good form — not grinding maximal attempts. Stay in the controlled strength zone, not the danger zone.

FAQ

FREQUENTLY ASKED QUESTIONS

Is it safe for cyclists to lift heavy?
Yes, when progressive and technique-led. Heavy for a cyclist means 4–8 rep sets at a load where form stays solid throughout. Introduce load gradually, film your technique early, and the risk of injury is low.
What rep range should cyclists use?
4–8 reps for primary compound movements to build maximal strength. 6–10 reps for accessory work. Avoid the 15–20 rep range as a primary approach — that's muscular endurance, which your riding already provides.
Won't heavy lifting make my legs too sore to ride?
There's an adaptation period of 3–4 weeks where delayed-onset soreness can affect subsequent rides. Schedule strength after hard rides, not before. After the initial adaptation, soreness becomes minimal.
How heavy is heavy enough for a cyclist?
Heavy enough that the last 2 reps of a 6-rep set require genuine concentration and you couldn't safely do 3 more. This is roughly 70–85% of your 1-rep maximum, which sounds daunting but is a moderate, controlled working load.
Should older cyclists lift as heavy as younger cyclists?
The case for heavy loading is actually strongest for masters riders, not weaker. The neuromuscular stimulus from heavier work is precisely what counters the age-related decline in fast-twitch fibre. Adjust load based on what you can do safely, not on age alone.
