Difficulty: Moderately Easy
Step1
Lie on your back and grip a single body blade with both hands, holding the blade horizontally just above your chest. Remember to keep your abs engaged and your tail bone tucked in slightly to protect your back throughout the exercise.
Step2
Bend your knees, bringing your feet flat onto the floor if you are just beginning to workout with a body blade. Begin to shake the blade up and down using quick, short movements. Slowly push the blade up until your arms are fully extended and then slowly bring it down again. Repeat your up and down presses to work the muscles of your chest.
Step3
Continue lifting the blade up and down, and move into a more advanced position if you feel capable. Slowly extend your legs out straight, resting them on the floor. Flex your toes, pulling them in towards your chest and continue the blade presses.
Step4
Get an even more advanced workout, strengthening your abs while you work your chest muscles, by lifting your feet slightly off of the ground. Keep your feet flexed and abs strong as you push the blade up and relax it down again. Continue these exercises for 2 to 5 minutes depending on your fitness level.
