Fitness tech questions

Do I need an expensive fitness watch to get results?

No. The fundamentals — step counts, heart rate, sleep — are tracked just as well by a band under $100. Expensive watches add nicer screens and more sports modes, but they don't make you fitter on their own.

Are chest strap heart rate monitors worth it?

If you train with heart-rate zones, yes. Chest straps read electrical signals directly from your heart, while wrist sensors use light and get thrown off by movement, sweat, and dark tattoos. For casual workouts a wrist tracker is fine; for serious training, a strap like the Polar H10 is the standard.

Will a smart scale actually help me lose weight?

It helps in the same way a budget helps with money: visibility. Seeing body-fat and muscle trends over weeks tells you whether your training is working, which keeps you motivated far better than a single number bouncing day to day.
