Today my client became a true believer that chalk makes a difference. So this morning training my client a female in her mid-late 20's weighing 108lbs, start our session with normal cardiovascular and movement preparation. Our first movement of the day Dead-Lift!!!. We began with just the 45-50lb Trap Bar slowing (Tempo-3010) going thru the movement for muscle memory and corrective purposes. Second set 95lbs15x movement was good but i couldn't help but noticed that she was struggling with the grip(connections between hand and the weight) more than the actual Lift. Realizing this we chalked up immediately sometimes people dont prefer it but nothing beats results. Well in this case her only backup was her gloves which can hurt more because while gripping the glove causes friction between the fingers causing pain. Now our last set we up the weight and still keep the same rep scheme for bragging purposes lol. Increasing the Deadlift to 115/15x which was a pretty impressive eye opener. Most commercial gyms don't allow chalk but I work at one of the best gyms in the country. Crunch Fitness where there's no "NO JUDGEMENTS". Come thru and train with the best;)
PRO: The advantage of chalk is adding grip in sports and weightlifting, which would be important for performance and strength gains.
CONS: Chalk gets freakin everywhere during your workout from the immediate start to finish. Plus some commercial gyms won't allow it because they don't want the responsibility of cleaning up after you more than they already do.
