Now hear this! Studies show that blasting tunes while working out can enhance results. A song's tempo should fall between 120 and 140 beats per minute — the range of most rock and dance tracks. Cue up songs that ramp up your energy level, like rock, rap and 80s dance remixes and then cool down with 10 minutes of soothing songs to catch your breath, says fitizens.com founder Debra Strougo.
