according grip

Width on which are placed elbows, does not change for different grips, she’s shoulder.

Supiniran, began – the role of foreign heads is reduced, the movement focuses on domestic, long heads.
Polusupiniran – power grip. Predisposes to repetitions with the highest intensity in compliance with the equipment and insulation of all grips.
