Funky Fitness Fads

Ultimately, getting in shape only takes a pair of sneakers and some motivation to get out the door and start moving! But there are some new fitness trends that are becoming pretty popular, and some top fitness experts are weighing-in on their effectiveness. Here's the low-down on three new fads. 
 
*Skorcher: This machine zeroes in on your rear-end in a rather specific manner, focusing on toning the buttocks and thighs by pushing out of a basic squat position. Personal trainer Jay Blahink says it may allow you to do specific exercises, but the machine is not always effective. You might want to save the money and stick to weighted lunges and squats.
 
*Yoga fusion: This update on a classic involves a blend of yoga, aerobic dance, cycling and boxing. The workout pioneers claim it's an ideal way to squeeze in cardio and sculpting, but Los Angeles-based trainer Kathy Kaehler say she thinks these classes give people a “false sense of what yoga is for and how it is practiced.” The good news? These workouts won’t hurt you either.
 
*RealRyder: It might sound like a device fit for a horse rider, but the RealRyder is actually an indoor bike that allows you to move from side to side. As an outdoor bike rider, Lombardi says she loves the $2,395 bike. But Blahinik says trying to gain balance on the RealRyder may result in a reduced calorie burn.
