A new and improved portable arm exercising apparatus, comprising:
- a belt assembly adapted to fit around and adapted to be secured to a waist of a user,
- a first support assembly connected to said belt assembly at a first location on said belt assembly,
- a first swivel assembly connected to said first support assembly,
- a first counterforce unit connected to said first swivel assembly,
- a second support assembly connected to said belt assembly at a second location on said belt assembly,
- a second swivel assembly connected to said second support assembly, and
- a second counterforce unit connected to said second swivel assembly, which is distinct and separate from said first spring retainer,
- wherein said first swivel assembly permits said first counterforce unit to swing in a substantially 180 angular degree arc around said first support assembly in a plane contiguous to a first plane, and said first swivel assembly permits said first counterforce unit to rotate substantially 360 angular degrees around said first support assembly in a plane contiguous to a second plane, wherein said first plane and said second plane are perpendicular to each other,
- wherein said second swivel assembly permits said second counterforce unit to swing in a substantially 180 degree arc around said second support assembly in a plane contiguous to a third plane, and said second swivel assembly permits said second counterforce unit to rotate substantially 360 angular degrees around said second support assembly in a plane contiguous to a fourth plane, wherein said third plane is substantially perpendicular to said fourth plane,
- wherein said first swivel assembly includes a first ring connected to said first support assembly, and a second ring connected to said first counterforce unit, wherein said first ring and said second ring are mutually inserted through each other,
- wherein said first ring of said first swivel assembly is oriented vertically contiguous to a first plane,
- wherein said second ring of said first swivel assembly is oriented vertically contiguous to a second plane,
- wherein said first plane is perpendicular to said second plane when said first counterforce unit hangs immovably from said first support assembly,
- wherein said second swivel assembly includes a first ring connected to said second support assembly, and a second ring connected to said second counterforce unit, wherein said first ring and said second ring are mutually inserted through each other,
- wherein said first ring of said second swivel assembly is oriented vertically contiguous to a third plane,
- wherein said second ring of said second swivel assembly is oriented vertically contiguous to a fourth plane,
- wherein said third plane is perpendicular to said fourth plane when said second counterforce unit hangs immovably from said second support assembly,
- wherein said first counterforce unit and said second counterforce unit each includes a loop connected to a respective first ring wherein said loop and said respective first ring are mutually inserted in each other, a housing assembly supporting said loop, a counterforce spring assembly housed within said housing assembly, and a hand grip assembly connected to said counterforce spring assembly,
- wherein said counterforce spring assembly includes a spiral spring, and a compression rod assembly for compressing said spiral spring when said hand grip assembly is pulled by a user, and
- wherein said compression rod assembly includes a first end which includes a first spring retainer for contacting a first end of said spiral spring, a stem portion which passes longitudinally through said spiral spring, a second end which passes through an orifice in said housing assembly and is connected to said hand grip assembly, and a second spring retainer, housed within said housing assembly, for contacting a second end of said spiral spring, and
- further including, a tension adjustment assembly for adjusting tension in said spiral spring.
