The Low Bridge works on mobilizing different joints and muscles than its brother the gymnastics bridge (Or high bridge).
In Floreio Flow work both bridge variations are used.

If it is interesting to you I invite you to try some floreio work together with your gymnasticbodies WOD. It is a great complement and allows you to use your newly developed strength in another way.
