Why do weightlifters usually apply some chalk powder on their hands before they lift weights?

Explanation

### Step-by-Step Solution:

1. **Understanding the Problem**: Weightlifters often struggle with grip when lifting heavy weights due to sweat on their hands. This sweat can cause their hands to slip, making it difficult to hold onto the weights securely.

2. **Role of Chalk Powder**: Chalk powder, when applied to the hands, serves a specific purpose. It is a drying agent that absorbs moisture, which in this case is the sweat on the weightlifters' hands.

3. **Absorption of Sweat**: When weightlifters apply chalk to their hands, the chalk absorbs the sweat. This reduces the moisture on their hands, which is a key factor that contributes to slipping.
