The adjustable resistance band assembly includes a first end, a second end, and a longitudinal axis extending therebetween. First and second resilient members are provided. An adjustment assembly enables a user to selectively engage the first or first and second resilient members to adjust the resistive force provided for performance of an exercise. ## Claims ### Claim 1 An adjustable resistance band assembly comprising: a sleeve with first and second ends and a longitudinal axis extending therebetween; a bore defined in the sleeve and extending from the first end to the second end; a first end cap provided at the first end of the sleeve; a second end cap provided at the second end of the sleeve, wherein the second end cap is selectively movable away from the second end of the sleeve; an adjustment disc disposed between the second end of the sleeve and the second end cap; a first resilient member extending between the first and second end caps; a second resilient member extending between the first end cap and the adjustment disc; and an adjustment assembly for selectively engaging the adjustment disc to the second end cap, wherein when the second end cap is moved longitudinally outwardly from the second end of the sleeve the first resilient member is stretched and wherein when the adjustment assembly engages the adjustment disc and the second end cap is moved longitudinally outwardly from the second end of the sleeve, the first and second resilient members are stretched. ### Claim 2 (depends on 1) The adjustable resistance band assembly of claim 1 wherein the adjustment disc disposed between the second end of the sleeve and the second end cap comprises a first adjustment disc and a second adjustment disc and wherein the second resilient member extends between the first end cap and the first adjustment disc and a third resilient member extends between the first end cap and the second adjustment disc. ### Claim 3 (depends on 2) The adjustable resistance band assembly of claim 2 wherein the adjustment assembly comprises a selector rod that includes a plurality of pins, wherein at least one pin of the plurality of pins is positioned for selective engagement with the first adjustment disc and at least one other pin of the plurality of pins is positioned for selective engagement with the second adjustment disc. ### Claim 4 (depends on 3) The adjustable resistance band assembly of claim 3 wherein rotation of the selector rod results in engagement of the first adjustment disc. ### Claim 5 (depends on 3) The adjustable resistance band assembly of claim 3 wherein rotation of the selector rod results in engagement of the first adjustment disc and the second adjustment disc. ### Claim 6 (depends on 2) The adjustable resistance band assembly of claim 2 wherein the adjustment assembly comprises ridges on the interior of the second end cap and in a first position said ridges engage the first adjustment disc and in a second position, said ridges engage the first and second adjustment discs. ### Claim 7 (depends on 6) The resistance band assembly of claim 6 wherein said ridges are moved between said first and second positions by rotating the second end cap. ### Claim 8 (depends on 6) The resistance band assembly of claim 6 wherein when said second end cap is in said first position, said ridges on the interior of the second end cap engage a tab on the first adjustment disc. ### Claim 9 (depends on 1) The adjustable resistance band assembly of claim 1 wherein the adjustment assembly engages the adjustment disc through rotation of the second end cap. ### Claim 10 (depends on 9) The adjustable resistance band assembly of claim 9 wherein the adjustment assembly comprises a rod positioned through the center of the second end cap to selectively engage the adjustment disc. ### Claim 11 (depends on 10) The resistance band assembly of claim 10 wherein the rod positioned through the center of the second end cap engages the adjustment disc via a pin positioned orthogonal to the length of the rod. ### Claim 12 (depends on 1) The adjustable resistance band assembly of claim 1 wherein the adjustment assembly comprises ridges on the interior of the second end cap and wherein when said second end cap is in a first position said ridges engage the adjustment disc. ### Claim 13 (depends on 12) The resistance band assembly of claim 12, wherein when said second end cap is in said second position, said ridges on the interior of the second end cap engage a tab on the first disc and a tab on the second disc. ### Claim 14 (depends on 1) The adjustable resistance band assembly of claim 1 wherein said first resilient member extending between the first and second end caps is engaged to the second end cap via an end disc engaged to the second end cap via a fastener. ### Claim 15 (depends on 1) The adjustable resistance band assembly of claim 1 wherein the sleeve is fabricated as a flexible material. ### Claim 16 (depends on 1) The adjustable resistance band assembly of claim 1 wherein the second end cap is connected to a workout accessory via a carabiner.
