## Claims

### Claim 1

An adjustable dumbbell comprising:
a body comprising:
a first end disposed opposite a second end;
a first side disposed opposite a second side,
wherein the first side comprises a first hand grip,
wherein the second side comprises a second hand grip, and
wherein the first hand grip is oriented perpendicular about a vertical axis to the second hand grip;
a third side disposed opposite a fourth side,
wherein the third side comprises a first receiving portion, and
wherein the fourth side comprises a second receiving portion; and
a hollow interior;
a first opening proximate the first end of the body;
a second opening proximate the second end of the body;
wherein the first hand grip spans a distance from the first end to the second end;
wherein the second hand grip spans a distance between the third side and the fourth side; and
at least one weight configured to be removably affixed to an outer surface of the third side, the fourth side, or a combination thereof.

### Claim 2 (depends on 1)
