Torch calories while toning your abs and arms with the bunny hop. Yeah, the name sounds cute, but this exercise is killer. We love adding a bit of cardio to the basic plank, and we also love how this move makes our abs and arms burn in the best way possible.

• Begin in a plank position with the feet together.
• Pull your abs in, and jump your feet to the right, bringing your knees toward your right elbow. Your torso will twist to the right.
• Jump your feet back to plank to complete one rep.
• Repeat on the other side, and continue alternating sides for 20 reps total.
