Money, or the lack of it, changes everything, and that includes how people will be working out in 2010.

In these belt-tightening times  1 , cost-conscious workouts（锻炼）at home and at the gym topped the list of fitness trends for this year in a survey, followed  2  by shorter, more time-efficient regimens, such as  3  boot camp（强力集中训练） and circuit training.

"People are looking  4  for ways to accomplish as much as possible with as little  5  time and money as necessary," said Cedric X. Bryant, chief science officer of the American Council on Exercise (ACE), which conducted the online poll of fitness professionals.

"Last year money was on the list but this  6  year the majority of the respondents put  7  it as one of the top," he added.

Bryant said some 600 ACE-certified fitness  8  professionals responded to the annual poll  9 , which the non-profit organization has been conducting for a decade.

Other money-saving measures  10 , such as the shift from personal training sessions to small group training  11  classes and in-home workouts  12  using smaller, more portable equipment, also made the list.

"Personal trainers are seeing they've got to respond to market needs  13  . Working with two to four clients at a  14  time they can charge less  15  but still get their hourly fee," Bryant said.

Boot-camp workouts and circuit training, both of which burn  16  calories while building strength and endurance（持久性）, will be among the most popular trends in 2010, as time-constrained（受压制的） consumers  17  seek shorter, more intense activities.

One bright spot is the rise of exergaming-type systems, like Nintendo's Wii Sports, Wii Fit and the PC-based Dancetown. Bryant says the fitness-based video games are turning up  18  in health clubs and senior centers.

Functional training workouts, which are geared to improving the quality of life and the ability to perform everyday tasks, will remain strong  19 , and the use of computerized tracking and online training and scheduling tools will increase  20  in the coming year.
