A yoga block system which includes a first block and a second block which
can either be rectangularly shaped or triangularly shaped. These blocks
are capable of joining with one another, releaseably, along either a
common face when the blocks are rectangular or along the hypotenuses when
the blocks are triangularly shaped. At least one of these blocks is
preferably hollow enabling a user to gain access to its interior.
Notwithstanding the elements used to join them, each block presents to a
user faces which remain substantially planar.
