TECHNICAL FIELD
[001] The present disclosure generally relates to exercising apparatus, more particularly, the present disclosure relates to load lifting exercise apparatus.
BACKGROUND
[002] Background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.
[003] In recent times, there has been massive increase in obesity across the world. According to a study nearly 30% of the world’s population is either obese or overweight; the rise in global obesity rates has been substantial and widespread, presenting a major public health epidemic in both the developed and the developing world. Thus, obesity is an issue affecting people of all ages and incomes, everywhere. Obesity increases health risks such as cardiovascular disease, cancer, diabetes, osteoarthritis, and chronic kidney diseases. Research indicates further that if obesity or overweight is left unchecked, the rise in obesity could lead to even deaths due to cardiovascular causes. Further, increase in obesity could lead to declines in life expectancy in future.
[004] Physical activity plays a pivotal role in burning off excess calories. Getting more activity increases your calorie burn, such that fat stored in the body can be used up that result in weight loss. Physical activity or exercise can improve health and reduce the risk of developing several diseases like type 2 diabetes, cancer and cardiovascular disease. Physical activity and exercise can have immediate and long-term health benefits. Most importantly, regular activity can improve quality of life. A minimum of 30 minutes a day can allow you to enjoy these benefits. Further, benefits of regular physical activity includes reduce risk of a heart attack, manage your weight better, have a lower blood cholesterol level, lower the risk of type 2 diabetes as well as some cancers, have lower blood pressure, have stronger bones, muscles and joints and lower the risk of osteoporosis, lower your risk of falls, recover better from period of hospitalisation or bed rest, feel better – with more energy, a better mood, feel more relaxed and sleep better. Also, a number of studies have found that exercise helps fight depression. There are many views as to how exercise helps people with depression. Exercise may block negative thoughts or distract people from daily worries. Exercising with others provides an opportunity for increased social contact. Increased fitness may lift your mood and improve sleep patterns. Exercise may also change levels of chemicals in your brain, such as serotonin, endorphins and stress hormones.
[005] Traditional weight machines are either plate loaded or weight-stack loaded. The plate loaded machines require the user to mount the desired amount of weight plates on the machine manually. The weight stack loaded machines require the user to select the desired amount of weight from a weight stack using a removable pin. The plate loaded machine requires locating the various load plates and manually adjusting the load. Also, the plate-loaded machines require the user to load and unload the machine, which can cause injury and can be a cumbersome task. The weight stack loaded machines on the other hand occupy more space compared to plate loaded. Further, the weight stack loaded machines require high maintenance cost also mostly the machines cannot be adjusted for different height and weight of the user.
[006] Further, operation of existing machines is a very complicated task and turns out to be fairly very complicated to be used by new user. Furthermore, maintenance cost of the machines is high and requires regular maintenance for efficient operation. Also, most of the existing machines do not allow the machine to be adjusted according to different height and weight of the user.
[007] There is therefore need in the art to develop an exercising apparatus that does not require weight stacks or weight plate loaded for exercise, and provide rugged, easy to use exercising apparatus that is cost efficient, requires less maintenance and can be customized for different height and weight of the user. Also, that is simple to operate.

[0045] In an embodiment, the lowering and rising of the handle 108 by the user can produce rotatory motion in the input shaft 102. The rotator motion of the input shaft 102 can be transmitted to the intermediate shaft 104 using the first gear assembly 114 with selective engagement configuration with the first set of gears 116. The first gear assembly 114 comprises one or more pivotally connected gears with assistance of one or more first levers. In an exemplary embodiment, the first gear assembly 114 can include three gears.

Further, from the table it can be easily deduced, that the gear ratios thus obtained are directly proportional to the standardized value obtained indicating the effort i.e. the gear ratio is directly proportional to the effort put by the user for exercising. It must be appreciated by the person skilled in the art that the a load lifting apparatus 100 allows adjusting the height of the user and also the user can adjust between various gear ratios for exercising using his own weight. The gear ratio allows the effort needed to be more or lower than the weight of the user.
