Muscle Control: Deltoid bounce

Rarity: Very rare

A rare muscle control performance, mostly because deltoids are very difficult to isolate and gain control over, deltoid bounce will be mostly witnessed by some performers who accidentally cause contractions to their deltoids during pec bounce performances (deltoid pseudobounce).

It is, however, possible to gain control over one or more of the three delt sets, usually the medial deltoid. It is unclear if one can gain control over all three delt sets or be able to control each separately, even though separate control of the posterior and arterior deltoid has been performed.

A few examples:
