Correct gripping is the most vital factor in badminton and winning matches is a true statement.
Explanation:
Correct griping is the basic skill which plays an important role in winning a badminton match. A correct grip helps to have better control over the racket, helps to maneuver swiftly to hit shots, and to extend the range of a shot, all of which lead to hitting efficient and winning shots in a badminton match.
An incorrect grip will lead to losing control of the racket, decreases accuracy and power in a shot and makes one hit loose or limited shots leading to losing the game.
A correct grip helps to avoid injuries, provides a cushioning effect to the wrist, helps to absorb sweat, and avoids blisters arising on palms.
Number 1 is mental and emotional health
I believe number 2 is physical activity (but I'm not 100% on that one)
and number 3 is going on a diet
