Why everyone needs to start using bosu balls

The Bosu ball is great for core strength and stability

Use the Bosu ball with a swiss ball to add an extra layer
of difficulty to your next work out. Strengthen your core, lower back, shoulders and arms by performing this drill.

Variations include 

• 1 foot
• 2 feet
• On toes
• On knee caps for those who have not yet the strength to go farther

 Hold for 45 - 60 seconds. Do as many sets as you feel necessary
