Lifting 5lb weights -- unless you're starting out not strong at all -- won't do much to increase strength. You know how, say, a crane can lift a 20,000-pound rock 10,000 times before it breaks, but lifting a 20-pound rock doesn't stress the crane one thousandth as much? Your muscles work the same way: lifting a 5-pound weight is not going to make you stronger at all. If you want to get stronger, you need to lift something your body thinks is heavy.

If you don't care about increasing strength but you just want to maintain muscle mass while decreasing calorie count, could you do that by just exercising with small weights, or would that be approximately the same as not weight lifting at all?

For example: https://www.mensjournal.com/health-fitness/if-you-want-build-muscle-and-gain-strength-lift-lighter-weights-more-reps/ https://www.mensjournal.com/health-fitness/if-you-want-build... > “Lift to the point of exhaustion and it doesn’t matter whether the weights are heavy or light.”
