Gym Exercise Equipment

How does the exercise equipment at the gym detect your heart rate. For example, the elliptical machine has the metal plates on the hand apparatus, how can the machine detect your heart rate. Thank you in advance

I have just bought a home treadmill and was wondering if a cheaper home quality treadmill with be as good as the treadmill in the Gym.

Will the expensive equipment at the gym make me lose weight faster because they are a better machine?

im trying to focus mainly on toning my butt legs and thighs and whittling my middle down ( well i want to keep my butt, just tone it more) what are any exercise equipment or workouts that will help me achieve my goal but not break my wallet im looking for very simple things that will deliver fantastic results
i just dont know where to start
resistance bands, weighted balls, stability balls, ropes, wieghts
i want some sort of equipment and keep it simple and easy to do or i might not keep it up if its too complicated

I started this thing where I have to do cardio four times a week for 20 minutes. I have three opportunities to do cardio for the rest of the week. I need to do cardio this evening, but I cannot go for a jog or ride my bike outside because it is raining (my parents wouldn’t allow me to) and I cannot go to a gym or fitness center right this moment. I also do not have any fancy equipment at my home.
What can I do for cardio?
I know it might sound stupid, but would jogging in place for 20 minutes work?

Any advice would be greatly appreciated
