"Mountain climbers are excellent for engaging the core while getting your heart rate up. They also strengthen your shoulders, arms, and legs while improving agility," Cooper says. Here's how to do a mountain climber:

• Start in a high plank position with your shoulders stacked directly over your wrists
• Drive your right knee into your chest with power.
• Return to the plank position.
• Repeat with your right leg.
• Continue to run your knees in, alternating your legs.
• Repeat for 30 seconds.
