Instructions
Ab Roller
Hold the Ab Roller with both hands and kneel on the floor.
Now place the ab roller on the floor in front of you so that you are on all your hands and knees (as in a kneeling push up position). This will be your starting position.
Slowly roll the ab roller straight forward, stretching your body into a straight position. Tip: Go down as far as you can without touching the floor with your body. Breathe in during this portion of the movement.
After a pause at the stretched position, start pulling yourself back to the starting position as you breathe out. Tip: Go slowly and keep your abs tight at all times.
Knee/Hip Raise On Parallel Bars
Position your body on the vertical leg raise bench so that your forearms are resting on the pads next to the torso and holding on to the handles. Your arms will be bent at a 90 degree angle.
The torso should be straight with the lower back pressed against the pad of the machine and the legs extended pointing towards the floor. This will be your starting position.
Now as you breathe out, lift your legs up as you keep them extended. Continue this movement until your legs are roughly parallel to the floor and then hold the contraction for a second. Tip: Do not use any momentum or swinging as you perform this exercise.
Slowly go back to the starting position as you breathe in.
Repeat for the recommended amount of repetitions.
