Suspend your TRX at around knee height. Grab the handles in each hand and lean back. Maintain your body in a straight line and your arms fully extended retracting your shoulder blades. Spread your feet at shoulder width apart. Contract your pelvic floor and core while keeping your chest up.
Step backwards with your right leg making a 90º degree angle between your legs. Slowly lower your body down until your right knee almost touches the floor while you inhale. Make sure to keep your right shin perpendicular to the floor avoiding the rise of the heel. Pushing mainly from the right heel, jump moving your left knee towards your chest while you exhale. Land and slowly lower your body again. Make sure you don't move your torso backwards while you perform the exercise. Repeat the movement for the specified amount of repetitions and then repeat with the other leg.TIPS: To maintain the balance, try to move the feet always in the same line without crossing them.
