Another great feature of an elliptical workout is you can add variety by pedaling backwards.

另一个伟大的功能锻炼的椭圆是你可以通过添加各种脚踏倒退。

Both elliptical workouts and treadmill workouts will build bone density, burn fat, promote good cardiovascular health and increase your energy level.

两个椭圆训练和跑步训练将建立骨质密度，燃烧脂肪，促进良好的心血管健康，增加你的能量水平。

In the dark night; you can let the software into a white backlight state; in order to illuminate the darkness, but also allows the rapid cycle of 10-degree color changes; Disco can be shown the kind of brilliant light; can also choose the shape of light; it Can be a rectangle; could be turned into oval shapes; fun!

在黑夜中；你可以让软件变成白色背光状态；以便照亮黑夜，也可以让10种颜色循环快速度的变幻；可表现出迪厅的那种绚丽光芒；也可以选择灯光形状；它既可以是矩形；也可以变成椭圆形状；乐趣无穷！

Singer Leona Lewis and former Led Zeppelin guitarist Jimmy Page emerged as the bus transformed into a grass-covered carnival float, and the pair combined for a rendition of "Whole Lotta Love".
