Should I use light weights to avoid bulk?

There is no need. Choose a weight that makes the last reps of each set hard, whatever that weight is.

Will lifting weights make me bulky?

Updated 29 October 2026

Very unlikely. In trials with menopausal women, a few months of strength training brought clear gains in strength and only a small increase in lean mass. Building a lot of muscle takes years of hard training and eating to support it. What most women notice first is that stairs, shopping and getting up from the floor feel easier.

What the trials show

A 2023 meta-analysis of randomised trials in menopausal women found that resistance training had a small effect on lean body mass, with somewhat larger effects in programmes of more than 12 weeks. Strength improved more clearly than size.

That fits what Schoenfeld and others (2017) found across age groups: strength can rise quickly, while muscle size grows slowly.

What to expect instead

Everyday tasks feel easier. Track that with the home strength test.
Better strength and balance, which matter more as we age. See How to improve your balance after 40.
Support for your bones when the training includes loading. See Strength training for bone density.

If you ever feel you are building more muscle than you want, you stay in control: keep the weight the same instead of adding more.

Know your starting point: work out your daily protein with the protein calculator and check your strength with the home strength test.
