A running form training device for training a runner to properly position and move their arms includes a harness, a pair of bands, and a pair of cuffs. The harness can be donned by a user so that the harness is removably engaged to a torso of the user. The bands are resiliently stretchable. Each band is engaged to the harness so that the band extends from proximate to a front of a respective shoulder of the user. Each cuff is engaged to a first end of a respective band and is removably engageable to a respective wrist of the user. The bands draw the arms of the user toward the harness, thereby restricting movement and positioning of the arms to promote proper running form.

A portable exercise apparatus utilized for exercising, stretching, and training multiple muscle groups of the body of a user. The apparatus is adapted to be worn about the waist or carried as a bandolier about the user's body. The apparatus has at least one releasably closable pocket and fixation rings for securing and carrying accessories, such as attachable handles, suspension lines, and elastic bands. The apparatus and methods of use provide the user with a plurality of configurations for assisted exercise regimens and the flexibility to exercise anywhere.

Described herein are methods for determining a target musculoskeletal activity cycle (MSKC) to cardiac cycle (CC) timing relationship. The method may include detecting a signal responsive to a cyclically-varying arterial blood flow at a location on a head of a user; providing a recurrent prompt at a frequency of the heart pump cycle using the signal, such that the signal correlates with a magnitude of blood flow adjacent to the location, and the recurrent prompt is provided to guide the user to time performance of a component of a rhythmic musculoskeletal activity with the recurrent prompt; and guiding the user to adjust a timing of the component of the rhythmic musculoskeletal activity to substantially maximize a magnitude of the signal. In some embodiments, the method further includes generating the recurrent prompt by amplifying the sound generated by the blood flow in or in proximity to an ear of the user.

A quick folding agility ladder and methods of folding and opening the agility ladder are disclosed. In one embodiment, the quick folding agility ladder can comprise a plurality of rectangular ladder frames and a plurality of ladder rung sleeves connecting the rectangular ladder frames. The plurality of ladder rung sleeves can comprise a first rung sleeve and a second rung sleeve. The agility ladder can be folded into a quadrifolium configuration comprising four petal-shaped portions including a first petal-shaped portion, a second petal-shaped portion, a third petal-shaped portion, and a fourth petal-shaped portion. The first rung sleeve can form at least part of the first petal-shaped portion and the fourth petal-shaped portion and the second rung sleeve can form at least part of the second petal-shaped portion and the third petal-shaped portion.

The present disclosure relates to methods for improving healthfulness, e.g., improving cardiovascular health, stimulating weight loss, and/or increasing muscle size/tone in animal subjects, including human subjects. In one aspect, the method comprises applying a core weight to each of the front and/or rear limbs of an animal subject at substantially the same distance from the torso so as to be substantially symmetrically placed, and such that each core weight lies within the distal ⅔ of the limbs; and wearing the core weights continuously for 6-20 hours per day for at least 2 days per week for at least 2 consecutive weeks. In certain embodiments, each of said core weights has substantially the same mass which is 0.2-1.0% of the total body weight of the animal subject, and each of said core weights spans less than ¼ of the total length of the limb to which it is applied.

The exercising device preferably has a handle with a proximal end and a distal end and a swing arm having a first end and a second end. The proximal end of the handle is rotatably connected to the first end of the swing arm, allowing the swing arm to rotate around the proximal end of the handle in a “clock-hand” fashion. A connecting shaft and swing arm stopper prevent the swing arm and handle from becoming separated during use. The exercising device may further have a weight member positioned in a weight member recess located close to the second end of the swing arm. The weight member increases the difficulty of using the exercise device and is removably attached to the swing arm. A safety sleeve can fit over the weight member recess to prevent the weight member from dislodging during use.

Height-adjustable apparatus using a spring to urge forward and rearward undulating whippy locomotion. A hand-crawling embodiment enables users to engage in all-fours crawling locomotion while the body is conventionally situated in a two-legged orientation. A foot-bounding embodiment enables walkers, joggers, runners and jumpers to engage in forward and backward whippy locomotion. A crutch embodiment enables crippled or injured users to likewise engage in whippy locomotion.

An exercise apparatus including at least a first trapezoidally shaped portion, and a second trapezoidially shaped portion. In one embodiment, a plurality of trapezoidally shaped portions are provided. The trapezoidally shaped portions are arranged with respect to one another. The portions can be used to form curves or straight lines. Excercises are conducted by stepping into or on the trapezoidally shaped portions.

A racing tracking system and process includes one or more RFID-based tower units connected to a computer. Pairs of tower units may be positioned to provide redundancy of detection so that the front of a participant and the rear of a participant (where bibs may be worn) are detected. The redundancy of RFID-based tower unit detection of front and rear worn bibs assures that all bibs will be read, and improves on the accuracy of a participant's position being confirmed.

A system and methods for athletic drill training using networked devices is presented. The networked devices are placed to lay out a drill for an athlete, and they include a sound source to indicate to the athlete where they should be at a given time. The system and methods are flexible enough to be used for most athletic drills. An input device for indicating the athlete is near the networked device can be added for agility drills.
