Disclosed are systems and methods for plyometric fitness systems that facilitate constrained multi-directional movements. By utilizing a variety of constrained elastic resistance cords in conjunction with plyometric platform stations and performance patterns, this system enhances dimension, capability and variety to conventional agility and jumping drills. The disclosed plyometric platforms are designed for contrast training, or resistance loaded and unloaded exercises. This allows the muscles to adapt to the loaded exercises and then apply the “learned” movement to the unloaded exercise. This directly reinforces the movement and muscle exertion needed to perform powerful movements thereby enhancing athletic performance.

The present disclosure provides a jump detection system for inertial measurement unit (IMU) integrated with a barometric altimeter in the same device (IMU-baro). The processor is configured to record time-series data of both a vertical component of the measured IMU-baro acceleration and the estimated vertical velocity of the IMU-baro, detect a potential jump by comparing the vertical component of the measured IMU-baro acceleration to one or more acceleration thresholds, and, validate the potential jump by comparing a difference between a maximum velocity and a minimum velocity within a vicinity of the potential jump in the time-series data of the estimated vertical velocity of the IMU-baro to a velocity threshold.

An inflatable plyometric box having a first inflatable member adapted to be inflated to a pressure, a second inflatable member on top of the first inflatable member and adapted to be inflated to a pressure, and a connecting member connected to the first inflatable member and the second inflatable member which secures the first inflatable member to the second inflatable member. The first and second inflatable members incorporate drop stitch technology which provides substantial rigidity to first and second inflatable members when the first and second inflatable members are inflated to the pressures. Thus the inflatable plyometric box is substantially rigid to support a user landing on the top of the inflatable plyometric box. The inflatable plyometric box may include a stabilizing member which may be connected to the bottom of the inflatable plyometric box, wherein the stabilizing member is adapted to increase the stability of the inflatable plyometric box.
