There's a bewildering amount of exercise claims out there. If you try to search for "the truth about exercise" on Google, more than 42 million Web sites are returned.
There are claims for "the slow burn" and for "the fast and short workout." Some insist you need to exercise every day, and others say that you can be fit with one workout a week. Can you really get "massive muscles in minutes" or "six-pack abs in 10 minutes a day?" Can you do too much cardio? Can you be fat and fit? Do you really need to exercise at all? We talk with experts about how to separate health benefits from exercise hype.
Guests:
