Abdominal Chest Fly's

Lie on your back, centrally on the Bosu, whilst holding suitable dumbbells in each hand, extended out to your sides whilst keeping a nice bend at the elbow.

Exhale and lift yourself up to almost 90 degrees, whilst bringing the weights upwards inline with your chest, aiming to keep the arms bent at the same angle throughout the movement.

Inhale as you lower down to repeat the exercise, smoothly taking the weights out to your sides, at chest level.

Combining this upper body exercise will greatly increase the exercise difficulty, and help target the abdominal muscles.

You can progress this exercise by taking 1 foot off the floor to increase the balace required, or for those feeling really athletic, you can also bring 1 knee up towards your chest as you're perfroming the sit-up movement.
