The difference that matters
Muscle responds to tension and effort, not to the material providing resistance.
Both can create resistance. Weights are easier to load precisely; bands are portable and joint-friendly for many movements.

Muscle responds to tension and effort, not to the material providing resistance.
Bands become less convenient when very high resistance, stable lower-body loading or precise progression is needed.
A mixed setup often works best: weights or machines for major lifts, bands for accessory work, travel and movements that feel better with variable resistance.
Bands are sometimes marketed as the “safe” older-adult option and weights as the serious option. That distinction is too crude.
Muscle responds to tension and effort, not to the material providing resistance. Bands can make exercises challenging, while dumbbells and machines make progressive loading easier to quantify.
Bands become less convenient when very high resistance, stable lower-body loading or precise progression is needed. Weights require more equipment and can be intimidating for beginners.

Choose the tool that lets you train hard enough with good technique and repeat the plan consistently.
A useful comparison starts with the job you need done. For resistance bands vs weights after 40, the evidence should be judged on meaningful outcomes, not packaging, novelty or a single laboratory advantage. If two options can both work, convenience, tolerance, cost and consistency can reasonably decide the winner for an individual.
Context can move the practical answer. Age, medical history, medications, baseline diet or fitness, symptoms, dose, product quality and what someone is already doing can all matter. That is why the Fitness World verdict here is deliberately limited to the claim on this page: Bands and weights both work. For long-term progression, weights usually make the dose easier to measure; bands win on convenience.
