Certain exemplary embodiments can provide a system comprising a treadmill. The treadmill comprises a track and a weight stack. The weight stack is coupled to a harness coupleable to a user, the harness constructed to simulate pulling a weighted sled when coupled to the user as the user utilizes the treadmill. The weight stack is coupled to a handle graspable by the user, the harness constructed to simulate pushing a weighted sled when the user grasps the handle as the user utilizes the treadmill.
As sports science technology increases, weighted sled training has been proven to be beneficial. A weighted sled is used by a countless number of users at all levels and by many recreational users with the purpose of improving overall physical conditioning. There are two general styles of sled training. Users can either push or pull a weighted sled when working out. Some reasons why sled training is important for users are to improve acceleration, increase strength, enhance conditioning levels, recover from injuries, and/or prevent injuries, etc. In
These benefits are important to users and for everyday users for multiple reasons. To improve acceleration, the user can perform weighted sprints to help them have a faster start. To increase strength, the user uses muscles and joints from the entire body that are under stress due to the weight. When the muscle is broken down, it will rebuild itself in a stronger manner. To enhance conditioning, training muscle endurance over time allows a user to perform longer. Along with these benefits, the weighted sled can also help in injury prevention and/or recovering from an injury. This can be important because in most weight lifting there is an eccentric portion of the movement. This is the negative motion of the weight that must be done in order to perform the positive movement. For example, when bench pressing, the eccentric portion is lowering the weight to one's chest before pushing it up. This can cause injuries as well as cause stress on used body parts. In sled training, there is no eccentric portion of the workout. The user is either pushing or pulling the sled, but the user does not have to do one in order to get to the other. This is important because it allows for a decrease in injuries and helps one recovery from pre-existing ones.
A weighted sled can be beneficial to a user if used properly. Persons that want to get their body in better shape or improve their athleticism can utilize a weighted sled. The positives from using a weighted sled improve conditioning of a plurality of body parts. Besides recreational users, the weighted sled can be utilized by users for conditioning. Because weighted sleds help with speed, strength, and power, sled training can be used in such sports as football, soccer, hockey, track and field, bodybuilding, and many others. Because sled training affects a plurality of body parts, users can get positive results when using a weighted sled properly. Because of this, weighted sleds can be beneficial to many sports and activities.
Although weighted sled training can be beneficial for users, it also comes with potential challenges. In order to use sleds, a strip of field, turf, or other proper surface, often 10 to 50 meters long, can be utilized to have enough room to push or pull the sled. This creates a big problem for many gym owners and trainers because having such a strip of space can be difficult. Certain exemplary embodiments can provide for more convenient sled training for users.
In order to utilize less space, certain exemplary embodiments provide a device that combines a treadmill and a weighted sled. Such embodiments allow for a user to perform weighted sled type workouts without utilizing a strip of a field. This would save a lot of space and money because the device will be under approximately nine feet long. When designing a gym, only need a space of approximately 10 feet by approximately 5 feet in area is a lot easier to find than a 50 feet by 10 feet strip. The treadmill will replicate the sled training while taking up minimal space. Because space is no longer the issue, this could be put in almost any gym.
Part of the treadmill system, which can be motorized or not motorized, replicates the pulling of a sled and a part replicates the pushing of a sled. Certain exemplary embodiments make sled training more convenient. Combining a weighted sled and a treadmill will reduce the space needed and allow for more gyms to have access to sled training. The design has separate exercises combined into one machine. The back is constructed for pulling a sled and the front is constructed for pushing. Due to space and cost, certain exemplary embodiments utilize only one weight stack. Overall dimensions of embodiments can be important. Certain exemplary embodiments have approximate dimensions as illustrated in
Certain exemplary embodiments consider user safety. In certain exemplary embodiments, weights are placed in a rear portion of the system. However, such embodiments might have issues if a user happened to fall off the rear portion of the system. Because of this, other embodiments comprise weights placed in the front portion of the system. Certain exemplary embodiments provide guiderails on either side that can be easily grabbed as desired by a user. Certain exemplary embodiments provide brake activators that are in accessible locations in order to stop the treadmill when desired by the user.
In certain exemplary embodiments, a track of the treadmill can have an adjustable resistance. Such embodiments replicate sprinting on a field. Because the resistance can be changed, the can do anything from a fast sprint to a slow walk.
In certain exemplary embodiments, an option between pushing and pulling. Such embodiments provide a harness that can be attached from the rear, which causes replication of a pulling of a sled. The harness can be coupled, via cables and pulleys, to a weight stack. On the other side, there can be handlebars, which cause replication of pushing of a sled. When pushed, the weight stack is raised slightly, which impels a user to run faster and harder. Along with this, the user has the option to not utilize the weight stack and run freely on the treadmill. This will still replicates some aspects of sled training due to resistance of the treadmill track, but it will not have the added stress of the weights.
In sled development, a first prototype was designed without a motor. This is because the product was designed to produce resistance as users sprint. The machine that had weights installed in the front and used cables and pulleys to lift the weight.
Certain exemplary embodiments provide two methods of changing resistance. The first is the weight stack located in the front. In order for the user to maximize their workout, they will be raising a set weight. This causes the user to work harder than if they were just on a treadmill. Along with this, the treadmill belt can also have an adjustable resistance. For the prototype, there was a “car-like” braking system that could be altered in order to set the preferred resistance as illustrated in
Because certain exemplary embodiment provide for alternatives of pushing and pulling, the system comprising a weight stack can be used for both types of exercise. This makes it convenient for a user to transition between pushing and pulling. Certain exemplary embodiments provide a lever on a side guard rail that allows for the user to change the resistance while the system is being utilized. Adjusting the weights is straightforward by moving of a peg to a desired weight.
Simulations of both pushing and pulling of a sled are possible while using the system. These two exercises are performed utilizing the same weight stack. This means that pushing and pulling at the same time can utilize the same amount of weight.
Certain exemplary embodiments provide a braking system similar to that utilized with stationary bicycles. For example, certain exemplary embodiments utilize a fan to produce resistance and cause the user to work harder. Such fans can be noisy and take up significant space. Other embodiments utilize a flywheel and magnetic resistance to cause resistance to be higher.
Other embodiments utilize a magnetic system inside the rollers of the treadmill to provide an adjustable resistance. Such embodiments adjust a distance between the magnets and the wheel. The closer magnets get to the wheel, the harder it is for the wheel to rotate. In return, the user is compelled to work even harder. Conveniently, the can be able to change a level of resistance while they are using the machine.
Another common issue for most machines in a gym is the crashing of the weights if the user does not gently return the weights to a stack. Certain exemplary embodiments can comprise a hydraulic cylinder between the weight stack and the pulley. Such embodiments allow for easy return of the weights for the cases of a user stumbling or running out of energy.
Certain exemplary embodiments can incline a running surface to approximately 15 degrees to increase running difficulty. Certain exemplary embodiments can provide front legs that have a pin system to allow users to easily move the treadmill up or down to get a desired incline.
Certain exemplary embodiments provide brakes located on handles, higher handles for the pushing side, a harness hook, and/or a pulley stop on the pulling side, etc. Brake handles can be located on the front of the pushing side handles. Certain exemplary embodiments provide an emergency stop for when the user needs to slow down quickly. Certain exemplary embodiments provide handles of varying height relative to a system base. Certain exemplary embodiments provide a harness hook, which can be a small hook on the side of one of rear legs in order to hang the harness when not being used. Certain exemplary embodiments provide a pulley stop, which can be a metal piece added to the rear pulleys, so the cable does get pulled through the wrong way.
Certain exemplary embodiments provide a pair of adjustable front, pushing, handle bars. Such embodiments will allow the trainer to easily change the length and location of the bars with the use a wrench. Such adjustable bars are provided with adequate strength for rigorous use.
Certain exemplary embodiments provide for positive or negative adjustments to overall system dimensions. Certain exemplary embodiments can weigh between approximately 350-400 pounds. The total weight can be increased depending on the total weight of the stack, such as from approximately 150-250 pounds.
Certain exemplary embodiments provide a treadmill (see, e.g., treadmill 6100 of
The treadmill can comprise a brake activator (see, e.g., brake activator 13300 of
The weight stack is adjustable via a pin (see, e.g., pin 12200 of
The device provides resistance when it is pushed and the harness provides pulling resistance when worn by the user while running.
