Bosu Plank

Place your forearms on the floor, with your elbows directly under your shoulders, both feet extended back behind you.

Keeping your feet centrally on the Bosu, fix this position for as long that is comfortably possible by keeping your abdominal - lower back and buttock muscles contracted throughout.

All fitness levels should focus on gradually increasing the length of time in the position. Alternate each side to be worked for 2 - 3 repetitions.

The exercise can be made harder by raising one foot off the Bosu, or commencing the movement with the Bosu on its domed surface.
