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.
Frog Sit-Ups
Lie with your back flat on the floor (or exercise mat) and your legs extended in front of you.
Now bend at the knees and place your outer thighs by the floor (or mat) as you make the soles of your feet touch each other.
Now try pushing both soles and bringing them up as near you as possible while you keep the outer thighs on the floor (or at least almost touching it). Tip: In this position your legs should create a diamond shape.
Now, cross your arms in front of you by touching the opposite shoulders. This will be your starting position.
As you exhale flatten your lower back to the floor while curling the torso upwards. Tip: This will be like performing the first 1/4 movement of a sit up. Hold at the top position for a second.
As you inhale, slowly lower back to the starting position.
Repeat for the recommended amount of repetitions.
