许多没有健身房会员卡的人不知道该如何保持身材。其实只要有一点创造力和一些基础设备，就可以锻炼身体了。这不仅不难，而且有时甚至是一件有趣的事情。
Ways to Keep Fit Outside the Gym
Here are some lowcost ideas to keep fit outside the gym.
1．Stairs Running or walking up and down the stairs in your house or apartment building can be a great highintensity cardio (高强度的心脏强化训练) and leg workout. One choice for beginners is to add walking intervals(间歇) every few floors.
2．Mall Walking When walking outdoors is not a good idea, do laps (绕圈) inside your local shopping mall. For the average person, a quick onehour walk can burn 300 to 400 calories.
3．Home Workouts A workout DVD or even a quick online search to find indoor aerobic routines(有氧动作) can pay off when you have limited space. If you have weights, a skipping rope, a stability ball, or other equipment, you can combine those into a great full body workout.
4．Active TV Viewing Don’t want to miss your favourite TV show? Try jogging or skipping on the spot while you watch. Do squats or pushups during the commercial breaks.
