The Best Bet
Memorial Day drops the flag on summer and, by association, beachgoing, which makes it as much of an impetus to jump-start an exercise program as New Year’s. Beyond this NuMetrex sports bra’s support function, it can provide motivation. It’s made from a high-tech fabric with electrodes woven in; snap in a heart-rate sensor, and your beats per minute will be transmitted directly to the monitor (it was designed to work with the Polar system, sold separately) or to the treadmill on which you’re trying to break Justin Gatlin’s record (bra, $44.99 at Super Runners Shop, 360 Amsterdam Ave., nr. 77th St.; 212-787-7665).
