I spend a lot of time on not only playing badminton, but also learning as much as I can from various videos I have either found or been directed to. They were very helpful to me as a beginner and continue to guide my development as a player. Here are a few of the video resources I have found exceptionally helpful:
Split step (so important that it gets its own category!):
These are all relatively short and I continue to watch them from time to time to remind myself of the proper split step footwork.
Racquet Technique, Grip, Specific Shots:
Fu Hai Feng video – this video I’ve watched so many times and I think it is extremely good. It’s quite long at 25 minutes, but it is all exceptional information and instruction in my opinion.
Jimmy Lin – awesome videos here; compilation videos of shots made by professional players, a lot of footwork including two conditioning videos, some racquet technique, and proper grip.
Coaching Badminton – Lee Jae Bok, a former Korean player, teaches you proper form and technique, correction videos for how he thinks most club players play (that’s you!), and proper badminton etiquette.
Kowi Chandra – coach at bay badminton center; videos range from footwork, to racquet technique, to drilling. Camera angles are great and very good explanation by Chandra.
Diemo Runhow – wide variety of badminton drilling and fitness videos. The titles are in German so some exploration may be necessary, but well worth it!
matrix2596 – two coaches who are a part of a badminton television show where club players come to play in front of either of the coaches and are then corrected and taught proper form/technique/strategy to improve. The videos are not in English but there are subtitles. There are about 30 episodes and on some of the episodes there are two parts.
Keep in mind that every player or coach has a slight preference and unique style to how they play. Take all videos with a grain of salt; ultimately it is you who has to replicate what you will be learning. If one video works better for you than another, that’s great; don’t worry if you are doing something the right or wrong way as long as it works well for you and you can retain your balance and pressure on court! An example is how Lee Jae Bok prefers to keep his body centered towards the net when he smashes and his racquet to the side of his head while Kowi Chandra prefers his body sideways and his racquet above his head. Both ways serve the same purpose.
The following links are what I have found to be most useful websites regarding badminton techniques like different types of grip, footwork, etc. as well as websites that have detailed racquet reviews, and blog posts about all things badminton. Again, I am no expert, though I find these websites very useful.
Badminton Central Discussion Forums – This website is completely moderated and maintained by badminton players all across the world. Anything from the absolute basics of badminton to the difference between hard feeling and soft feeling string to detailed opinions about professional players is covered within this website. Starting out paying badminton this website helped me immensely and I wish I had found it earlier. You can make a free account and post whatever you feel like to which you’ll likely get a reply or two from fellow forum members. Some players even post videos of themselves at practice and get critiqued by other players or coaches.
Paul Stewart Advanced Badminton Coach – Paul Stewart is a badminton coach in the United Kingdom and has been since 1987. This website has awesome reviews on a very wide selection of racquets. Each review is highly in depth with comparisons to other similar racquets, common complaints that he has heard or seen, and an overall summary at the end. He also posts a lot of informative articles about basic badminton skills, training and exercise, strategy, and even nutrition. However, what stands out the most to me with this website are the racquet reviews.
