Pike Ups
The pike up is a fantastic exercise for your mid-section and it will also ask questions of your upper body strength and flexibility. This move can be performed using some fitness or furniture sliders on a carpet or with a cushion on a hard, smooth floor. Anything that minimises the friction between the floor and your feet. Keeping your legs straight pike your body up so that your feet come towards your hands. Go as far as your strength and flexibility will allow. Slowly and under control lengthen your body back to the starting position.
