Have your coach or a friend watch you and give feedback on when your arm and
leg have reached full extension (or over-extension or under-extension). If you
cannot keep your back flat with your arm and leg fully extended, this may
indicate a limited range of movement in the hips and/or shoulders.

DEAD BUG
The Dead Bug is an advancement upon the Bird-Dog, where a similar movement
is performed lying on the back. As with previous exercises, the most common
fault in Dead Bug technique is arching of the back.
To perform a Dead Bug correctly, the core should be braced in Position 1, with
the back flat against the ground. As the arm and leg extend towards Position 2,
the back must remain flat, maintaining pressure on the ground. If the back
begins to arch, the athlete will feel feedback at the top and bottom of the
Corsuit.
