Twisting on the upper block

Twisting on the upper block is the technique of the exercise:

1. Kneel at the cable routed through the top block.
2. Grasp the rope and lower it down until his hands will not be in front of your face.
3. Slightly lean forward. This will be your initial position.
4. On the exhale, straining the abdominal muscles, start to curl up, bringing your elbows to mid-thighs. Hold this position.
5. On the inhale slowly return to starting position. Tip: during the exercise keep your abs in constant tension. Also do not place too heavy a weight, as in this case, the main work will be in the lower back.
6. Complete the required number of repetitions.

Variations: use the handle instead of rope to perform crunches to the side to study the oblique muscles.
