ABSTRACT:
A portable exercising apparatus for a supine user has an open ended inwardly tapered member with a block member inside, the position of which is adjustable. The block member has a channel which provides a passage for a pair of ropes frictionably engageable between the tapered and block members which frictional engagement is variable because the position of the block member is adjustable. The ends of the ropes emerging from one end of the channel, out of the tapered member, each have a hand grip, while the other ends of the pairs of ropes are joined to form a pair of loops slidably engaged in a tube which provides for adjustment of the length of the loops. A pair of bands are slidably secured to both loops by a sleeve, these bands providing containment for the feet of the user. Preferably the tapered member is made of a material having a high heat conductivity and the block member of a material having low heat conductivity this minimises the temperature rise due to friction. A temperature indicator is included in the block member to monitor the effort expended by the user in overcoming the frictional resistance.
