Isometric Isolation - There is a lot of emphasis on form in T-Tapp, but it
is also important to remember that isometric isolation is part of that
proper form. T-Tapp uses isometric isolation of muscles (your muscles
are tight and actively engaged in the movement) to create long, lean
muscles. (REMEMBER - relax muscle - bulk! Tight contracted muscle -
means long lean muscles with inch loss) Isometrics means both
insertions of the muscles are being pulled, thus you create long, lean
muscle fibers.

For instance with Plies not only must you have correct KLT, core curled,
ribs lifted, and shoulder alignment; you must also keep isometric
isolation of your leg & thigh muscles at all times. And when you are
doing the arm movements, you must squeeze your arm muscles tight
throughout the entire sequences while moving your arms in the correct
position (behind the ears, shoulder & elbows level, etc...) think to use
donut fingers (pinch them) and imagine that there are 2 people REALLY
pulling those arms away from you, and do this without releasing your
lats, abs or lower body.  It is also called FULL FIBER ACTIVATION…
layman’s terms… meaning “No Spaghetti Arms.”
