Unit 125：Run yourself more ragged at the gym第125单元：让自己在健身房里耗尽精力Exercising on gym or health club equipment,rather than walking or running on your own,tends to give you a harder workout.不要只靠自己散步或跑步，到健身房运动或使用健身倶乐部的器材会使你运动得更激烈。Treadmills,rowing machines and equipment like the Stair-Master get more of your body involved.使用踏步机、划船机及阶梯运动器材使你的身体更充分地活动。What's more,many people find that the sight of other people sweating it out at a gym pumps up their own energy levels.而且，许多人觉得看到别人在健身房里汗流浃背的样子会使他们自己充满精力而想运动。
