Ab Crunch Machine vs Frog Sit-Ups

Select a light resistance and sit down on the ab machine placing your feet under the pads provided and grabbing the top handles. Your arms should be bent at a 90 degree angle as you rest the triceps on the pads provided. This will be your starting position.

At the same time, begin to lift the legs up as you crunch your upper torso. Breathe out as you perform this movement. Tip: Be sure to use a slow and controlled motion. Concentrate on using your abs to move the weight while relaxing your legs and feet.

After a second pause, slowly return to the starting position as you breathe in.

Repeat the movement for the prescribed amount of repetitions.

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.
