A cyclist walking into the gym for the first time at 45 has a different job from a rider who has spent twenty years under a bar. They might be the same age, riding the same distance and preparing for the same event. Their starting weights should still be different.
That is where strength training after 40 begins: with what you have done, what you can do comfortably and the riding you want to support.
What Andy Galpin said on Roadman
Asked whether someone over 40 who has avoided strength work for years has missed the chance to improve, Galpin replied: “The window is not even remotely closed.” He then explained why the goal, existing riding volume and recovery capacity matter.
That is a reason to find a suitable starting point. It is not a promise that every rider will improve at the same rate. Listen to the original conversation or read our guide to measuring strength progress.
Take stock before you start
Write down your recent lifting experience. If it belongs to a distant winter, say so. Note the equipment you can use and the times you can realistically get to it. Then look at the cycling already in your week.
For a newcomer, the first task is learning the movements. A qualified coach can watch what an app or written programme cannot see: how you move, where control breaks down and whether the weight is appropriate. If pain or a health condition affects your exercise, seek suitable professional advice before adding load.
For an experienced lifter, the starting point is the work you have recently tolerated. Old personal bests are history; your last few weeks are more useful when deciding what goes on the bar today.
Choose the work you can do well
Machines, free weights and single-leg exercises all offer ways to train. The choice should fit your experience, equipment and purpose. Our gym-exercise guide explains those options.
A split squat deserves its place because it suits the programme and you can perform it well. Its resemblance to one-legged pedalling is not enough to make it the best exercise for every cyclist.
The same applies to repetition ranges. Turning 40 does not automatically assign you four to eight reps. The load and number of repetitions need to make sense together, within the programme you are following.
What the research supports
A systematic review of heavy strength training in cyclists found improvements in cycling performance, efficiency and anaerobic power. The evidence was rated low certainty. It supports taking strength seriously, while leaving questions about the best programme for a particular rider.
In a small 25-week study of elite cyclists, the group combining strength with endurance training improved several performance measures and increased lower-body lean mass. That is a useful reminder that gym work can change more than one thing. It is not a prediction of what a 48-year-old club rider will achieve.
Research provides a starting point. Your training record helps you decide whether the programme is fitting the person doing it. The main strength guide goes further into the evidence.
Find a place in the week
Mark the rides that matter before looking for gym time. Check the day after each possible slot as carefully as the slot itself. A strength session has to fit with the work that follows it.
Two weekly sessions can be a workable structure. One reliable session may be a better starting point when time is tight. Our minimum-dose guide explains how to make that choice, and the strength-session planner helps you compare the available days.
Keep the first block simple enough to learn from. If you change the gym programme, add riding hours and start a new diet in the same week, it becomes difficult to work out why you feel different.
Keep a record worth reading
After each gym session, record the weight, reps and effort. Add a short note if something felt uncomfortable. Over the following days, note how the important rides went.
Review the pattern alongside sleep, fuelling and the demands of work. One difficult day rarely gives you the whole answer. Repeatedly struggling through rides you used to manage is a reason to review the plan.
Let your goal determine what you follow. A rider preparing for a long sportive needs to know whether the planned riding is becoming manageable. A racer may be watching a particular effort or repeatability late in a session. Keep the conditions comparable when you test, and resist giving the gym all the credit for an improvement in a week when several things changed.

Editorial correction, 7 September 2026: Earlier wording overstated what age alone establishes about repetition ranges and frequency, and implied guaranteed tissue changes and injury protection. Those claims have been removed.
