The move: One legged burpee 

The standard burpee made challenging. The one legged burpee is great for strength and speed and will work almost every muscle in your body.

The difficulty level: Try to keep your balance and ensure you are engaging your core. When you jump up make sure it's strong and powerful. 

The burn factor: 9/10
