Get into Low Plank position (plank on your elbows/forearms), feet slightly wider than hip-width with straight legs. Shift your balance onto one arm, and with the un-weighted arm, reach under your chest and as far to the opposite side as possible (as if reaching for a glass of water beside you). Return to Low Plank and repeat to the other side.
