1 . A lot of us spend most of our working day sitting at the computer without moving at all. So, how does the world keep fit? Let’s have a look at some of the latest exercises from around the world.

Towerrunning is a sport you can do in the tall buildings of almost any big city. All you need to do is start at the bottom of an office tower and run up all the stairs until you get to the top. Now, towerrunning has become popular with important races taking place in some of the world’s tallest towers, like the China World Trade Centre in Beijing.

Piloxing started in the USA. The sport is a mix between boxing, pilates (普拉提) and dance. Piloxing uses the power and speed of boxing, while building your muscles and strength with pilates. All of this happens to non-stop loud music, and you learn some great dance moves too.

Paddle boarding on the ocean might look easy, but it is a tough sport. You need to be strong to keep your balance. The sport was adapted from surfing and it had its roots in Polynesia where people used paddling for both work and play-from transport to catching waves.

Trapeze may remind you of the circus act-people fly, dance and move from side to side through the air. Jules Leotard developed the art of trapeze in the mid-nineteenth century in France. To perform trapeze, people must develop upper-body strength to turn and fly.

Are you ready? Even a short amount of exercise every day can help us to feel happier and more relaxed.

2 . Indoor Skydiving

Have you ever dreamt of flying? Have you ever wanted to experience the excitement of skydiving, but didn’t want to jump out of a plane? Indoor skydiving has opened up a whole new world for you to try flying.

Indoor skydiving is an activity, simulating（模拟）the free fall of a skydive. That means you learn to fly in a column of air produced by a wind tunnel （风道） inside a limited area. Before flying, you need to wear certain equipment to protect you. And each of you is equipped with an instructor that helps you learn to control your body while flying. But you aren’t trained to be more aware in the sky as a normal skydiver.

To be an indoor flyer, you can be at all ages. Fear of height or lack (缺少) of experience won’t stop you from trying. The only real limitation preventing people from flying is weight limit. Countless physically challenged flyers have safely flown with the help of experienced instructors.

Although indoor skydiving gets its name from skydiving, the similarities between the two are actually very few. The one they are in common is in the sense that they both share the freedom of flying.

However, in traditional dives, skydivers usually step out of a plane from more than 10,000 feet high, while indoor skydiving just needs flyers to lean forward and lie on the air. Also, being an outdoor activity, skydiving depends on the weather. The wind, rain, or snow can cancel your plans to jump. Indoor skydiving removes this effect from the picture. Normally, a skydive lasts just between 45-60 seconds, but tunnels allow skydivers to fly longer and as much as they like.

While most people put skydiving in the must-do list, indoor skydiving is much more than that! What used to take skydivers tens of thousands of jumps and years of experience can be learned in a relatively shorter period of time. Skydivers could be trained at lower cost compared to being trained in the sky. Because people of all ages can fly, children are quickly becoming some of the most talented skydivers. Thus, all these will certainly benefit the development of skydiving.
