Monitors can go strapless

Love monitoring your heart rate, but hate wearing the tight, uncomfortable transmitter chest strap? You're not alone, as the sudden rise of the strapless heart rate monitor indicates. Popular with walkers and gym rats but viewed skeptically by hard-core athletes for a perceived lack of accuracy and potential danger during cycling (you have to take one hand off the handlebar to get a reading), strapless monitors come in convenient wristwatch and finger-ring form. There's even a breakthrough design that incorporates a chest transmitter into a bra and shirt.
