In an embodiment, the strap-based exercise apparatus includes one or more infinity loops configured to attach various portions of the exercise apparatus together. The exercise apparatus may be provided as a kit including an elongated member, a grip assembly, and one or more mechanisms for adjusting the length of a strap and connecting straps together. ## Claims ### Claim 1 A method for configuring and using an inelastic exercise device, wherein the inelastic exercise device comprises an elongated member having a pair of ends separated by a length, a first loop formed by folding a first portion of said elongated member against a second portion of said elongated member, wherein said second portion of said elongated member is proximate said first portion of said elongated member, and a second loop formed by folding a third portion of said elongated member against said second portion of said elongated member, wherein the third portion of said elongated member is proximate said second portion of said elongated member, said second loop is proximate said first loop, and said second portion of said elongated member is secured to said first portion of said elongated member and said third portion of said elongated member, the method comprising: securing the elongated member to a structure by wrapping a first end of the elongated member around the structure and removably attaching the first end of the elongated member to the second loop using a first strap attachment mechanism; removably attaching a grip to the first loop using a second strap attachment mechanism; and performing an exercise by applying force to the grip. ### Claim 2 (depends on 1) The method of claim 1, wherein the elongated member further comprises a third loop formed by folding a fourth portion of said elongated member against a fifth portion of said elongated member, wherein said fourth portion of said elongated member is proximate said second end of said elongated member, and a fourth loop formed by folding a sixth portion of said elongated member against said fifth portion of said elongated member, wherein the fifth portion of said elongated member is proximate said fourth portion of said elongated member, said fourth loop is proximate said third loop, and said fifth portion of said elongated member is secured to said fourth portion of said elongated member and said sixth portion of said elongated member, the method further comprising: increasing a distance between the grip and the structure by removing the second strap attachment mechanism from the second loop and removably attaching the grip to the third loop using the second strap attachment mechanism. ### Claim 3 (depends on 2) The method of claim 2, wherein the method further comprises: decreasing the distance between the grip and the structure by removing the first strap attachment mechanism from the second loop and removably attaching the first end of the elongated member to the fourth loop using the first strap attachment mechanism. ### Claim 4 An inelastic exercise device comprising: an elongated member having a pair of ends separated by a length; a first loop formed by folding a first portion of said elongated member against a second portion of said elongated member, wherein said second portion of said elongated member is proximate said first portion of said elongated member; a second loop formed by folding a third portion of said elongated member against said second portion of said elongated member, wherein the third portion of said elongated member is proximate said second portion of said elongated member and said second loop is proximate said first loop; wherein said second portion of said elongated member is secured to said first portion of said elongated member and said third portion of said elongated member; wherein said first portion of said elongated member is proximate a first end of said pair of ends, said inelastic exercise device further comprising: a fourth portion of said elongated member proximate a second end of said pair of ends and said third portion of said elongated member; and a third loop formed by folding said fourth portion of said elongated member against said third portion of said elongated member, wherein said third loop is proximate said second loop; wherein said fourth portion of said elongated member is secured to said third portion of said elongated member; further comprising: a strap attachment mechanism secured to said first loop; a grip secured to said second loop by a first inelastic strap; and a strap lengthening mechanism secured to said third loop. ### Claim 5 (depends on 4) The inelastic exercise device of claim 4, wherein said grip is a hand grip, a second inelastic strap is secured to said grip and is configured as a foot grip, and said first inelastic strap and said second inelastic strap each pass through said grip. ### Claim 6 (depends on 4) The inelastic exercise device of claim 4, wherein said first inelastic strap is movable through said second loop. ### Claim 7 (depends on 4) The inelastic exercise device of claim 4, wherein said first inelastic strap is immovably secured to said second loop. ### Claim 8 (depends on 4) The inelastic exercise device of claim 4, further comprising: a second strap comprising a first end, and a second end, and a strap restraint configured to constrain said second end forming an open loop; wherein said first end comprises a closed loop; and wherein said open loop is operatively connected to said strap lengthening mechanism such that a distance between said strap lengthening mechanism and said first end is adjustable by moving said second strap through said strap lengthening mechanism. ### Claim 9 (depends on 8) The inelastic exercise device of claim 8, wherein said closed loop is removably connected to said strap attachment mechanism so as to secure said inelastic exercise device to a structure. ### Claim 10 A kit for assembling an inelastic exercise device, the kit comprising: an elongated member having a pair of ends separated by a length, the elongated member comprising: a first loop formed by folding a first portion of said elongated member against a second portion of said elongated member, wherein said second portion of said elongated member is proximate said first portion of said elongated member; and a second loop formed by folding a third portion of said elongated member against said second portion of said elongated member, wherein the third portion of said elongated member is proximate said second portion of said elongated member and said second loop is proximate said first loop; wherein said second portion of said elongated member is secured to said first portion of said elongated member and said third portion of said elongated member; a grip assembly comprising: a first inelastic strap; a hand grip attached to the first inelastic strap; and a second inelastic strap adjustably connected to the first inelastic strap via a strap length adjustment mechanism; a first strap attachment mechanism configured to removably secure said first loop to said second inelastic strap; and a second strap attachment mechanism configured to removably secure said second loop to a structure so as to support said elongated member.
