(18) FIG. 1 illustrates a side view of one embodiment of an adjustable resistance apparatus 2, wherein the adjustable resistance apparatus 2 comprises a frame 4, an electric winch 6, a control box 8 and a control cable 74 (shown further illustrated in FIG. 7 below). The frame may further comprise a universal mounting bracket assembly 10, a set of vertical poles 12, an upper cross-member 14 and a lower cross-member 16.

(19) In an additional embodiment, the electric winch adjustably increases or decreases the tension on an elastomeric resistance band 18, which may attaches to the user's waist, or numerous other areas, at an attachment point 20.

(20) FIG. 2A illustrate a side view of an embodiment of the side portion 9 of the mounting bracket assembly 10, which attaches to the side rails of a treadmill by means of a set of winged bolts 22. The mounting brackets 10 are adjustable by sliding the winged bolts 22 to the appropriate position in a winged bolt slot 24 and then tightening the winged bolts 22 to a treadmill frame. The mounting brackets 10 further comprise a 16-gauge steel material. FIG. 2B illustrates a side view of a rear portion 28 of the mounting bracket 10, which prevents the side portion 9 from sliding along the side rail of the treadmill while a user exerts force upon the elastomeric band 18, which is attached to the adjustable resistance apparatus 2 by means of an electric winch 6 (shown in FIG. 1). The rear portion 28 further comprises an adjustable clamp 30 locking mechanism, which is tightened by one or more winged bolts 22, and may be attached to a variety of treadmill types.

(21) In another embodiment, the mounting bracket further comprises a downtube 26, the top 32 of which attaches to the set of vertical poles 12 and anchors the vertical poles 12 to the treadmill (Shown in FIG. 1). The downtube 26 further comprises a curved pipe, the shape of which allows for maximum contact between the side portion 9 of the bracket and the side of a treadmill, which increases the stability of the overall system, while still positioning the vertical poles 12, winch 6, and elastomeric band 18, as far toward the back of the treadmill as possible. Positioning of the adjustable resistance apparatus toward the far rear of the treadmill provides the user with plenty of space to move on the treadmill, particularly for users with long gaits. The top 32 of the downtube 26 further comprises a threaded inner radius, into which the vertical poles 12 can be removably threaded for quick and simple assembly and disassembly.

(22) FIG. 3 illustrates a side view of a single vertical pole 12, which attaches to the top 32 of the downtube 26 by means of a threading mechanism. The bottom of the vertical pole 12 comprises a thread 34, which mates with the thread on the inner radius of the top 32 of the downtube 26. The vertical pole 12 further comprises a series of holes 36 along its length, which mate with locking hitch pins 56 (shown in FIG. 5) to hold the lower cross-member 16 (shown in FIG. 1). The locking hitch pins 56 are easily attached and removed and enable the lower cross-member 16 to slide up and down the vertical poles 12 when detached. The lower cross-member 16 can be reattached by inserting the locking hitch pins 56 into any of the holes 36.

(23) FIG. 4 illustrates a front view of the upper cross-member 14, which provides structural support to the adjustable resistance apparatus 2 and is adjustable in length to fit the width of a variety of treadmills. The upper cross-member 14 further comprises a first set of two exterior pipes 40 and a first center pipe 42 with smaller diameter than the first set of exterior pipes 40. The first center pipe 42 fits into each of the second exterior pipes 40 and is adjustably fixed by a first pair of compression nuts 44. When the first compression nuts 44 are loosened, the first exterior pipes 40 may be pulled apart, exposing more of the first center pipe 42, so as to increase the length 46 of the upper cross-member 14. Likewise, the first exterior pipes may be pushed closer together, shrinking the length of exposed first center pipe 42 and the length 46 of the upper cross-member 14. Each of the exterior pipes 40 further comprise collars 55 on each end that fit over the tops of vertical poles 12 and lock into place using locking hitch pins 56.

(24) FIG. 5 illustrates a front view of the lower cross-member 16, which holds the electric winch 6 in place. The lower cross-member further comprises two hollow receiver ends 54 oriented perpendicularly to the portion of the lower cross member 16 that holds the electric winch 6 in place. The receiver ends 54 fit over the vertical poles 12 and may slide up and down the vertical poles 12 to adjust the height of the winch 6. The lower cross-member 16 is held in place by a set of locking hitch pins 56 wherein the lower cross-member may be adjusted to a variety of heights and locked in place by inserting the locking hitch pins 56 through the receiver ends 54 and into the holes 36 of the vertical poles 12.

(25) The lower cross-member 16 further comprises a second set of exterior pipes 58 and a second center pipe 60 with smaller diameter than the second exterior pipes 58. The second center pipe 60 fits into each of the second exterior pipes 58 and is adjustably fixed by a second pair of compression nuts 62. When the second compression nuts 62 are loosened, the second exterior pipes 58 may be pulled apart, exposing more of the second center pipe 60, so as to increase the length 46 of the lower cross-member 16. Likewise, the second exterior pipes 58 may be pushed closer together, shrinking the length of exposed center pipe 60 and the length 46 of the lower cross-member 14. A set of winch bolts 61 secure the winch 6 to the lower cross-member 16.

(26) FIG. 6A illustrates a top view of the winch 6, which in one embodiment comprises a 12-volt DC heavy duty gear motor 64 and a 1.5-inch diameter drum 70 winch 66, which are housed in a frame 68 and attached to the lower cross member 16 (Shown in FIG. 1). The elastomeric band 18 attaches to the 1.5-inch diameter drum 70 winch 66 on one end and to the user's waist on the other end (shown in FIG. 1). The elastomeric band 18 may further comprise a variety of elastic compositions and tensions varying from 10 pounds to 50 pounds. The bands 18 are easily interchangeable. The user must only tie a knot 90 at the end of a desired band 18 before dropping the knot 90 into a slot 92 on an outside edge 94 of the drum 70. Different ranges of band 18 resistance can be achieved with different band 18 types. In addition to increasing/decreasing resistance by winding the winch 6, the user may select a tauter band 18 such that less winding of the winch 6 provides more resistance. In another embodiment, the winch 6 uses an 84-rpm motor with a torque stall of 84 pounds per square inch. The winch 6 has a chain drive with a 3:1 gear ratio 72, which provides a maximum nominal torque of 189 pounds. The maximum force capable of being exerted on the user in the present embodiment is approximately 30 pounds.

(27) FIG. 7 illustrates a block diagram of the overall system 75, control box 8, which connects to the winch 6 via a control cable 74. The winch motor 86 is controlled by Bluetooth® via a smart device 76 application. In another embodiment, the control box 8 further comprises a microcontroller 78 with a Bluetooth® receiver and transmitter 80, a 12-volt power supply 84 and winch relay 82. In another embodiment, the microcontroller receives data from the smart device 76 to activate the winch motor 86.

(28) The microcontroller 78 supplies the appropriate voltage and polarity to the relay 82, which activates the winch motor 86. The microcontroller 78 tracks the number of revolutions of the drum winch 70 and, through an algorithmic process, a microprocessor 88 converts the number of revolutions to a relative force value exerted on the user. The relative force value will be within a range of 1-10 and will be transmitted through Bluetooth® to the smart device 76 application and display on the smart device 76.

(29) The user may remotely adjust the resistance of the band 18 either during use, by means of an application on the user's phone or other mobile device. The user can also program pre-determined workout routines, in which the winch 8 automatically winds at desired times. For instance, the user can set up a program to have a resistance level of 1 for the first five minutes of the user's warm up. After 5 minutes, the resistance level will increase to 3, then to 6 for the next 5 minutes, then back down to 3 for the next five minutes, and finally back to level 1 for the last 5 minutes of cooldown.

(30) FIG. 8 illustrates a flow diagram 200 instructing a user regarding donning, preparation, calibration and operation of the present system. At step 202 the resistance apparatus attaches to a treadmill by adjusting winged bolts on the lower mounting bracket assembly (shown in FIG. 2A). Then cross members 14 and 16 connecting both arms of the apparatus adjust by sliding the central bar through exterior pipes until reaching the appropriate width for the treadmill.

(31) In one embodiment, the lower cross member 16 may be leveled with the user's waist by adjusting a set of locking hitch pins 56 through the vertical poles 12. After mounting the apparatus and adjusting for a secure fit, at step 204 the user may select a tension band of with the desired resistance. As previously described, the apparatus accommodates a range of resistance bands which are easily mounted and dismounted for tension change as necessary. The band is tied to the rotating drum of the winch and threaded through the motor towards the front of the treadmill. At step 206 the user opens the mobile application on their phone or associated electronic device. The mobile application connects to the microcontroller through the Bluetooth capabilities of the smart device. A user can control the device connection to the apparatus within the app (shown in FIG. 9). At step 208 the user selects a workout within the app including the resistance level, interval, and length of time for the session. The app then directs the apparatus to calculate the relative force based on the resistance selected and turn the winch until this force is reached. The application gives the user feedback on the force being applied and displays it on the smart device.

(32) At step 210 the user can monitor the workout in real time through the mobile application. The user may change workout parameters manually at any point during the workout using controls in the mobile application. If the user does not make any adjustments, the application directs the apparatus to continue the original protocol. After completing a workout, at step 212, the Bluetooth® connection control in the app manually disconnects the mobile application from the apparatus.

(33) FIG. 9 illustrates an associated mobile application for controlling the resistance apparatus. The mobile application may possess a start button 110 to initiate a sequence and associated inputs to adjust all the relevant workout parameters. The user may set the rest time 90, the resistance level for the workout 92, the length of the workout 94, and the number of intervals 96 for pre-programmed resistance workouts. Manual adjustments of elastomeric resistance band 18 may be made via a tighten button 97 and loosen button 98.

(34) The workout status 100 is also displayed in order for the user to determine whether the workout is active, or paused. Additionally, a time display 102, adjacent to the workout status 100 indicator, monitors the elapsed time of the workout. Thus, a user can pause and resume their workout by selecting the status indicator.

(35) Moreover, a Bluetooth® connection control system may provide a connect button 103 and a disconnect button 104, displayed along the bottom of the screen allows a user to connect the mobile application to the microcontroller of the resistance apparatus. FIGS. 10-21 illustrate the stepwise method for setting parameters and initiating a workout. Initially, a user connects the mobile application to the device by selecting the Bluetooth® connection control input 106.

(36) The user then selects a device from a list of previously connected devices, FIG. 11. The application no longer displays a “Connect” input once a device has been successfully connected 108. Before beginning the workout, the user may adjust the band tension for rest and warm-up periods by directing the application to turn the winch securing the band. The user turns the winch to tighten or loosen the band by pressing and holding the respective input 110 moving the winch in the desired direction.

(37) Next a user inputs the workout parameters. The warm-up/rest interval, as set out in seconds is selected in the first box 112. This value sets a warm-up interval at the beginning of the workout and rest intervals alternating throughout the workout. The application displays a list of default times a user can select for the rest interval 114. Alternatively a user may enter a custom time period. The selected time is displayed on the workout screen in the first box 116. Workout level 118 determines the amount of resistance the winch applies to the user by tightening the band during a workout interval.

(38) The application again displays a list of values 120 from which a user selects the desired level. Potential input values from the list represent an algorithmic process where the microprocessor converts the number of revolutions to a relative force value exerted on the user. The relative force value will be within a range of 1-10, or an alternate appropriate range value determined by the system. Again after selection the system displays the designated level in the appropriate field on the next screen 122.

(39) Workout period and Number of Intervals are selected in a similar manner. The Workout Period 124 describes the length of time in seconds when the winch is applying greater force to the user by rotating to a position determined by the previously selected Workout Level. The Number of Intervals 128 determines how many times the system alternates between the workout interval and the rest interval. A user selects the desired field and populates each with an option from lists displayed by the application 126 & 130.

(40) Next, the user confirms the selected values displayed along the top of the screen 132. Once all the parameters for the workout are set the user can start the workout by selecting the start button 134. The workout status monitor 136 activates and maintains the time and current interval of the workout. The status monitor will change between warm-up, workout, and rest depending on the current phase of the workout. After completing a workout, the user can disconnect the application from the device by selecting the disconnect Bluetooth® control input 138.
