I agree with Mat's call, but i dont use small weights in the forms.
My Sifu has shown me several different types of VT specific weights drills.
Things for improving elbow power, punching power and stepping power etc.
None are using very heavy weights but merely applying a little resistance to certain actions for more benifit. Some can make you faster, or more powerful, without compromising relaxation / tension etc
There are other examples of adding resistance to your training without using actual weights.
I notice some people practice Bui Sao wilst using the elbow, where as when i 'practice' it in form i have my elbow straight and just pivot/rotate my wrist 'only' for greater resistance. (some lineages do it this way all the time in the form)
I also from time to time hold the thin end of my Lok Dim Boon when doing certain actions so as to make the far end heavier thus giving me a greater resistance helping endurance, stance stucture etc.
Mocking the weight 'training' idea only shows a difference of opinion or a narrow mind....
which one are you ?
