I'm no expert but can speak from my own experience and what I've read. I think if you work up to it slowly and do a moderate form of exercise, such as walking or riding a bike at a moderate speed, you can easily work up to 3-4 hours per day in a somewhat short time. Suddenly jumping into a 'big exercise' program can result in stress fractures or other stress-related injuries [speaking from personal experience!!!] but I know lots of people who hike every day and often more than 3-4 hours at a time. In fact, some of my hiker friends are retired so they're handling this level of exercise with older bodies.
BUT - none of them started out at that level - it's best to increase your activity level slowly - so instead of suddenly starting to walk 10 miles a day, for instance, get your baseline first and increase it by 1/2 mile at a time, approx 10 minutes or 1,000 steps. Don't increase more than once a week, better to increase even slower than that,
I know we ALL want to jump in like they do on the show - it's truly amazing progress!! But as has been pointed out already, each participant was very carefully screened and they are constantly monitored. Although the broadcast show implies they are spending 6-7 hours a day with intense exercise, the truth is that they spend most of their time in much more moderate exercise AND they take plenty of naps, from what I've been told. One participant said they workout 1-2 hours with about 10% of it more intense and the rest moderate [like walking], then they nap for an hour or two before doing any more. They don't have any outside influences - that is, no television, newspapers, talking with family or friends - the ONLY thing they do is focus on their health. And - if you've noticed, there are medical people on hand 100% of the time they are working out, just in case something happens - and when it does, the participants are put on low-level exercise until they recover.
Good luck with your summer - hope you get the results you are hoping for!!
