Heart Rate Monitor Help

nicoleeoff

I'm a beginner when it comes to working out, and I'm doing my best to slowly increase my strength training and cardio. I would like to get a heart rate monitor to more accurately gauge how many calories I'm burning. I looked into pricing and they run from $20.00 - $400.00!!!

1) Do I really need to invest in this?
2) How do I begin to decide which one is the right one for me?

Any advice is greatly appreciated. Thanks!
