Not Sure, How or What type of Chalk to Use?
Here’s My Guide on Gym Chalk.
What Is ProsourceFit Professional Grade Gym Chalk?
Overview:
ProsourceFit Professional Grade Gym Chalk comes in firm, semi-hard blocks. One box contains 8 blocks, each weighing 2 oz/ 56g per block, 1 lb / 450g in total. Like most of the quality chalk available, it is 100% magnesium carbonate that is easy to apply to hands.
You can crush it into powder; it will become smooth & soft when in powder form. As a drying agent, it’s good at absorbing moisture & keeping your hands dry to secure your grip.
Gets the job done for barbell & heavy dumbbell lifts, pull-ups, static holds & your regular hand spring gripper training. One pound means there is a bulk of chalk in one package, lasting you probably for years.
Ideal chalk for a simple home gym. A solid choice for powerlifters, bodybuilders, weight lifters, cross-fitters, and gymnasts.
What are the Pros & Cons of Block-Style Chalk?
Wastes Less & Lasts Longer
Pros:
- Improves Grip – Simple physics, secures your hold, adds friction between your hands & the object you want to lift
- Keeps Your Hands Dry – Removes moisture from Hands, keeping your hands dry throughout intense workouts
- Blocks Can be Broken Down to Powder – You can choose how to break chalk blocks down into smaller bits or turn them into powder
- Block chalk is the Least Expensive – This is the most basic, traditional form of chalk. Typically sold in larger quantities, & overall it costs you less
- Multi-Purpose – Good option for most athletes – powerlifters, bodybuilders, weightlifters, rock climbers, cross fitters.
- 100% Magnesium Carbonate – Simple usually works the best & in most cases, this is all you need to secure a grip well
- Convenient – Comes in a 1 lb /450 g box that contains 8 x individual 2 oz / 56 g chalk blocks that are ready to use
- Wastes Less & Lasts Longer – Individual, small blocks alleviate messy, loose chalk, making it waste less & last longer
Cons:
- Can Damage Skin – In case of excessive use of chalk, you need to wash your hands properly after every workout. As a drying agent, it will eventually damage the palms of your hands in case you don’t clean them thoroughly
- Inevitably Causes Mess – Many commercial gyms won’t allow chalk. Nobody wants to clean someone else’s mess. Excess chalk can get all over the place & also affects the equipment you’re using
