Q: its the yellow one on the right that criss crosses underneath it: Can you be a little more specific ? There are two yellow machines on the right. One is a man lift and the other is a mixing hopper of some kind. The green piece of equipment is some kind of auger that looks like it may be for dispensing some kind of material. The white piece of machinery with the bucket loader under the hopper is called a BobCat. Some of these machines do not look familiar as being used here in the US. The photos are showing how the company's drive hubs are being used in different situations. I don't see that they describe the different pieces of equipment. Sorry I couldn't help more.

Q: Is the use of exercise machinery the best way to get fit?: The use of fitness equipment such as elliptical, treadmills, weight training stations at the local gym are the best ways to improve your overall physical fitness. You can receive instructions on how to use the equipment by the Fitness Center monitors at your local gym. If you join a gym you will be amongst like-minded people. You may meet someone there who can become your gym partner and you both can give each other incentive to obtain physical fitness. You can also gain fitness with yoga and pilates to help with your flexibility. Zumba, Core and dancing classes can help with your cardio. These are suggestions but you must make the commitment to stay with your excercise program. Healthy eating habits, limiting alcoholic beverage consumption and not smoking tobacco products will help in your quest for physical fitness. It will not do you any good if you work out for three weeks and give up your fitness program. Oh, by the way, it will be beneficial to you if you have a complete check-up with your doctor before you start your lifetime practice of physical fitness. When you go to the gym you want to walk into the building under your own power. You do not want to be taken out of the building on a gurnee. It is very embarrasing and humiliating with people looking at you as you are wheeled out by paramedics, place in an ambulance and driven to a hospital. Good luck.
