The present disclosure relates generally to inclined exercise equipment, and more particularly to a foldable hack squat and leg press machine that enables a user or person to perform hack squat and leg press exercises, and adaptable to vertically fold into a compact form for storage when not in use.
In recent years, there has been a tremendous increase in the number of persons interested in physical fitness in general, and in particular those involved in various types of exercise. Many people use various types of exercise equipment to strengthen body parts. This exercise equipment enable a user to increase strength, endurance and balance, burn calories, increase muscle mass, improve agility and coordination, and increase overall performance in a sport or other task.
Many individuals struggle to find enough time in their schedules for a complete workout at a health club or gym and they can perform different exercises at home in their free time. However, exercise equipment such as hack squat and leg press machines are bulky devices that take up a lot of floor space in gyms as well as in homes. Furthermore, the exercise equipment may necessitate permanent installation. For installing the exercise equipment, technicians and special tools are required, which adds additional cost to the users or individuals. In addition, the exercise equipment are also difficult to disassemble and require more space for storage even when not in use.
Specialized exercise and fitness equipment and machines are often designed to concentrate resistance forces on certain muscle areas of the user. Exercise equipment and other fitness equipment are frequently built to accommodate more than one sort of exercise. Such combination designs are more resource-efficient than single-exercise machines, both in terms of cost and space. Cost savings are obtained when one machine or piece of equipment can provide many workouts rather than several machines or pieces of equipment each delivering only one of the physical activities.
Combination exercise machines take less room than several exercise machines to do the same workouts, resulting in more efficient accommodation. However, combination fitness equipment or exercise machines are sometimes difficult to reconfigure, necessitating real dismantling or physical separation and movement of individual sections or portions of the equipment or machine. Such issues have previously been the norm when seeking to give exercises with an angled weight sled.
In existing technology, a collapsible seat for a combination hack squat and leg press machine is known. A hack squat platform is operably mounted to a frame for performing a hack squat exercise. A collapsible seat is operably connected to either the frame or the hack squat platform for use in performing a leg press exercise. The collapsible seat and the hack squat platform are provided as alternative configurations whereby only one of either the collapsible seats or the hack squat platform can be used by the individual at one time. However, here the exercise machine utilizes more space, which is difficult to the user to be positioned in their residence or a gym.
Therefore, there is a need for a foldable hack squat and leg press machine that utilizes less space to be positioned in their residence or a gym. There is also a need for a foldable hack squat and leg press machine that is easily foldable to a size that allows to easily storage and is easily unfolded into a useable state that allows for exercising multiple muscle groups. There is also a need for a foldable hack squat and leg press machine that is folded vertically when not in use, thereby reducing the amount of floor space required to store the unit and creates more space in the room. There is also a need for a foldable hack squat and leg press machine that enables the user to position it at multiple angles based on user requirements for performing the hack squat and leg press exercises. Further, there is also a need for a foldable hack squat and leg press machine that can be folded vertically to reduce its footprint.
