We all know that a healthy life means     1     (get) both plenty of exercise and enough good-quality sleep,     2     reality often gets in the way. The new research indicates that doing enough exercise could make up     3     some of the unhealthy impacts of terrible sleep.

Cancer, for example, those at the unhealthiest end of the sleep and exercise scale had a 45 percent higher risk of dying from cancer    4     those with good sleep and doing exercise     5     (regular). However, that risk just about disappeared for those     6     didn’t have good sleep but kept regular physical activity.

The weekly amount of exercise     7     (recommend) by the World Health Organization (WHO) is 150 minutes of moderately intensive activity, or more than 75 minutes of vigorously intensive physical activity.

“Levels of physical     8     (active) at or above the lower threshold recommended by WHO appeared to cut out most of the associations of poor sleep and mortality,” write the researchers in their paper.

“Considering that physical activity     9     (be) perhaps more achievable than sleep, the study offers people more health     10     (reason) to be physically active; and provides health professionals with more reasons to recommend physical activity to patients with sleep problems.”

4 . If you want to stay in shape, but don’t have the time to go to the gym, the Mobile Gym is a good solution. It’s basically a large bus filled with the latest fitness equipment. You can find everything you need for a complete workout, and here’s the best part — you don’t need to go to the gym, and the gym comes to you!

The Mobile Gym was the idea of Adam Zickerman, founder of Inform Fitness, a popular chain of gyms across the United States. It hit him when he ordered lunch from a food truck one afternoon. So why not put a gym on a truck?

Zickerman experimented with a few designs and then invested $60,000 on making adaptations and fixing machines. He didn’t really need an advertising budget as the bus advertised itself. Carole Pallmeyer, for instance, found herself driving behind the Mobile Gym one day. At first she thought it was a regular bus with ads for a gym. But then she realized the bus itself was a gym, so she booked workout sessions for her entire family. “We are all busy, but we know the bus is coming and make sure we are home at 4:30 for the workouts,” she said. “You forget you’re on a bus because the workouts are tightly scheduled.”

Unfortunately, it is illegal to use the fitness equipment while the bus is moving, so you don’t get to save time by working out during the rush time. It operates only once a week, only two clients (客户) can be accommodated at a time on the bus. And it doesn’t come cheap. Sessions start at $100, while in-house workouts are $65. But the Mobile Gym appears to be a big hit.

“There are so many benefits to having the Mobile Gym come to you,” Zickerman said. “Only five to seven exercises complete a total-body workout when performed using our special equipment.” He also added that a 20-minute workout might sound easy, but it is really difficult and provides instant results. “It is very challenging and clients understand quickly why rest is important between workouts ”
