Abstract: Running-end spool containment devices and systems are described herein that allow a user to secure a running-end of a strap within a lockable device to anchor the running-end of the strap at a selectable length when the device is in a locked mode, and to enable the running-end of the strap be lengthened or shortened when the device is in an unlocked mode. In an embodiment, the device includes an axel about which the running-end of a strap can be wound and unwound, a lock case that can engage the axel to prevent axel rotation in the locked mode and that can be disengaged from the axel to allow the axel to rotate freely in the unlocked mode, and a spring case that causes the axel to rotate and the running-end of the strap to wind around the axel when the lock cases is in the unlocked mode.

Abstract: A locking rotational suspension training system is described that includes a locking rotational device within which a user can secure a strap to anchor the strap when the device is in a locked mode, and to enable the strap to move freely through the device when the device is in an unlocked mode. The locking rotational device includes a wheel and brakes that clamp around the wheel to prevent wheel rotation and secure a strap there between in a locked mode and that are positioned away from the wheel to allow wheel rotation and permit the strap to move freely in an unlocked mode. Such a locking rotational device enables a user to lock a strap at any point along its length thereby allowing the user to engage in a full range of bodyweight rotational, static, symmetric and asymmetric exercises, as well as weighted “pulley type” exercises.
