ABSTRACT:
Support structure is provided for support in elevated position above a support surface upon which a user may be disposed. An elongated section of flexible tension member is mounted from the support structure by guide structure mounted thereon and the tension member includes releasably joined opposite ends. The tension member is supported from the guide structure for longitudinal shifting relative thereto and with a closed loop of the tension member depending downwardly from the support structure. The guide structure includes adjustable friction brake structure for yieldingly braking the tension member against longitudinal shifting relative to the guide structure With the brake structure adjustably applied, the reach of the tension member furthest from the support structure may be used by a climber and the friction braking on the tension member may be adjusted to effect a friction drag against longitudinal shifting of the tension member which is equivalent to less than the weight of the user. In this manner, the user may exercise his arms in the same manner in which a person climbs a rope, but with less climbing effort than otherwise required by the user. In addition, a horizontally elongated seat structure is provided with clamp assemblies at its opposite ends releasably engageable with the depending reaches of the tension member to thereby provide a swing and a horizontally elongated chinning bar is also provided with clamps at its opposite end for releasably clampingly engaging the depending reaches of the tension member.
