Not for Everyone continued...
If you're using an audio-only workout, you have to visualize what the trainer means and hope you're doing it the right way, adds Push.TV's Mike Monroe.
Even the pod workouts that include video present their challenges. The tiny screen may be difficult to see, and some workouts show only a starting and finishing position -- leaving you to wonder just what the correct form is during the actual exercise.
"You're not going to get the same correction you would from a trainer in a gym," says Monroe.
Another drawback, says ACE spokesperson Gregory Florez, is that "anyone can throw one of these programs up on the Web."
Unless you research the presenter's credentials, you could wind up with a workout developed by someone with no real training or experience. In those cases, "at best, you'll get an ineffective workout," says Florez. "At worst, you can wind up being injured."
The Future of Fitness?
When all is said and done, is MP3 fitness the wave of the future?
"It's affordable; you do it on your schedule; it's varied; and it's built around your needs," says fitness trainer Jennifer Gianni, whose Fusion Pilates DVD series is available as customizable pod workouts at podfitness.com. "I don't think it gets any better."
Mike Monroe, on the other hand, thinks this is just one more tool to take advantage of.
"There will always be different workout personalities … those who want to work out at home with a DVD, those who want to go to the gym and work with a trainer, those who simply want to do their own thing, and those who enjoy the latest technology," says Monroe.
"Downloadable workouts appeal to a particular segment of the workout population, but I don't see this as taking over," he says.
But as far as recorded exercise programs go, Jung believes podcasting is the future. It's easy to search for the type of program you want and download it, she says. She also likes the idea that students can respond to instructors directly through email, and can rate the programs on podcast search sites.
"And as an instructor, I love the fact that I can deliver fresh new material quickly," she says.
