I learned this exercise from Tony Horton, the creator of P90X3. The dolphin hop focuses on your core and upper body. I liked it a lot! I even practiced it after class Tuesday night.

You start in the Plank position:

With your feet together, legs straight, you use your core to lift your hips up and you hop your feet in.

Return to your starting position and repeat!

I love learning new exercises. It keeps me motivated as a personal trainer and group instructor, and it helps challenge my body as well as my clients!

Do you like learning new ways to challenge your body?
