What is how to have manly hands?

As an AI language model, I don't have personal preferences, but here are some general tips to develop rougher, manly hands:

1. Build your muscles: Make sure to hit the gym and work-out your arms. Include exercises such as pull-ups, deadlifts, and rows to build bigger forearms.

2. Try hand exercises: Grip strengtheners, dumbbell wrist curls, and reverse wrist curls are some exercises that help in building hand muscles.

3. Avoid gloves as much as possible: Try and do tasks that require handwork, such as yard work, carpentry, or mechanics. Avoid wearing gloves for these activities to allow your skin to thicken from contact with hard and rough surfaces.

4. Avoid too much moisturizing: Don't use moisturizers too frequently, especially after doing manual labor that toughens the skin.

5. Manicures: Keep your nails trimmed and clean to maintain a proper look. A standard manicure helps in preventing brittleness, which can lead to cracks and injury, thereby helping to maintain more muscular, manly hands.
