Steps
Step 1: Stand up facing the TRX anchor; holding onto the handles, which are set to mid-length.
Step 2: One leg is straight (front leg), with the foot flat on the floor, the other leg (back leg) has the foot off the floor and is bent at 90 degrees, with your knee facing the floor.
Step 3: Proceed to lunge back, bending the front leg to 90 degrees, bringing the back knee towards the floor, without actually touching the floor.
Step 4: ‘Drive’ yourself back up by pushing with your front foot and pulling on the TRX straps; swing your back knee up in front of you to complete the motion.
Step 5: Repeat the movement several times before switching legs.
How to progress the exercise
This exercise can be progressed to one leg for a greater challenge. Another progressive challenge would be to remove one or both arms off the floor and cross them on your chest. The greatest challenge, of course, would be to do both one leg and arms crossed against your chest.
Additional Information
Great care must be taken to assure the glute muscle is firing throughout this exercise, as it is easy to overuse the lower back. Also, if progressing to one leg, be very careful to avoid rotational movements during the exercise- bracing of the core muscles come more into play here.
