Courtesy Photo Using a heart rate monitor (HRM) is smart: It shows you how hard you're working -- and when you need to work harder. What's really genius: NuMetrex, an Adidas-owned company, just debuted the best alternative to a heart-rate strap -- a sports bra with a built-in slot for your heart rate monitor and HR-sensing fibers in the actual fabric. Five reasons why that rocks?
1. It makes life simpler. You wear a sports bra to the gym no matter what, right? So, when you're laying out your workout clothes the night before (we know you all do that, to help you automatically get #UpNOut), choose this baby and connect your heart rate monitor onto the snaps inside the bra (you know, where you'd normally put it on a regular HRM strap). It's compatible with any HRM. Now, in the morning, you won't have to worry about putting on an extra piece of gear.

The HR sensing fibers work well, so unlike a typical heart rate monitor strap, you don't have to spend time re-adjusting the placement of the sensor in order for your watch or phone to detect it (which is the worst...it can totally kill a good workout vibe).
3. Goodbye sucky HRM strap. It's always too tight, too loose or chafes like crazy, right? Now, in its place, you've got a supportive, comfy new sports bra. Boom.

5. You can be twinsies with your guy. NuMetrex makes a men's shirt that has snaps on the outside to lock in a HRM underneath the chest bone. Perhaps a holiday gift for the male fitness aficionado in your life.
