Difficulty: Moderately Easy
Step1
Lie on your back on a comfortable surface and extend your legs straight out in front of you. Flex your feet, pulling your toes in towards your body. Remember that to protect your spine and work your core muscles, your abs should be engaged and your tail bone should be tucked in.
Step2
Hold a body blade in each hand. Place your upper arms flat on the ground, bending your elbows at 90-degree angles and lifting the blades. The body blades should be positioned so that they are parallel to the ground and vertical with your body.
Step3
Lift your elbows slightly and begin to shake the blades up and down using fast, short movements. As you get used to the movement, slowly extend your arms, continuing to shake the blades. Lift your arms until they are fully extended, just as you would with a chest press, and then slowly lower them again. Repeat for 1 to 5 minutes, depending on your fitness level.
Step4
Perform chest flies by using the same basic technique, simply open your arms out to the sides as you shake instead of extending upwards. Slowly lower your forearms down towards the ground, and lift in slow, controlled motions. Again, repeat for 1 to 5 minutes.
