Abstract: An advanced calisthenic ring comprising a substantially annular shape and various contiguous and smoothly interfaced regions within multiple planes to avoid abrading a user's arms when a user is performing a muscle up exercise. In some embodiments the device can also comprise a support element integral with the advanced calisthenic ring to aid a user in adopting a false grip position and/or facilitate performance of a muscle up exercise.

Abstract: Disclosed is a dispensing system a dispenser having a first chamber containing a first material and a second chamber containing a second material. The dispenser is configured to selectively retract one of the chambers at least partially within the other to transition the dispenser between an extended position and a compact position. The first chamber includes an open top end that is, before use, covered with a first breakable membrane. A breaker ring, at least initially covered with a second breakable membrane, is configured to break the breakable membranes when the dispenser is transitioned between an extended position and a compact position. In the compact position, with the membranes broken, the first material and second material are free to form a mixture that can be dispensed via an opening in the dispenser's openable tip.

Abstract: Disclosed is a dispenser having a first chamber containing a first fluid and a second chamber containing a second material. Each chamber has screw threads that are selectively joinable so that the first and second chambers are twistable relative to one another. The first chamber includes an open top end that is, before use, covered with a breakable membrane. A breaker ring is located within the second chamber and is configured to break the breakable membrane when the dispenser is transitioned between an extended position and a compact position. In the compact position with the breakable membrane broken, the first fluid and second material form a mixture that can be dispensed via an opening in an openable tip.
