Not a whole lot of training equipment is needed at first in martial arts training but companies like Asian World of Martial Arts, Wing Lam Enterprises, Martial Arts Mart, Tiger Claw, Kwon, Century and others do supply a huge array of equipment and have been in business for years if not decades.
For Wing Tsun equipment:
Wing Lam Enterprises has specific gear for the International WingTsun™ Association, North American Section. Once you become a member, your instructor can help you order whatever you need. Beyond the basic uniform, in the coming months you might want a pair of shin guards, a chest protector, a head guard and maybe a pair of protective gloves. On the gloves, Wing Tsun normally does without these. However, under a limited set of circumstances, the gloves protect your knuckles more than it does your training partner!
A three-section wall bag is a recommended and an important purchase for training punching and even kicking power in WingTsun upon reaching your second student grade rank in Leung Ting Wing Tsun. You might start considering where you will mount it. It is strongly suggested that you find a block wall to do so.
Leung Ting WingTsun® has wooden dummy training. However, the 116 Wooden Dummy techniques are taught only to Technician Level instructors. If you are just starting, you have time to get fully set up with a wooden dummy.
Leung Ting WingTsun® teaches weapons but not until the Technician and Practician Levels. Insofar as self-defense against weapons, this is taught much earlier in the student grade ranks. Getting a plastic or rubber knife and a padded stick can be worthwhile once you are instructed in their proper use! That about sums up your equipment needs for years to come!
