Stability and strenght is important for every athlete, especially in complex open sports like badminton. Strong legs are the key to move fast and efficient but a good stabilty will also decrease your injury risk dramtically. Besides that only a strong core will allow you to create power the legs so I always try to implement core exercises into my workouts.
Please be careful with your equipment if you work out at home and check if there is enough space when you do the racketswings! I am very lucky to have a high ceiling at home, so overheadshots are no problem. If you have not enough space above you, you can also do the overheadexercises on your knees (except the one where you give the racket between your legs) The effect will almost be the same or it can sometimes even help to focus more on the arm movement when the hip and legs cannot move.
