There seems to have been allot of talk about how to develop timing and hand speed. Personally, I have found that doing light contact sparring (hands open in gloves) and working the DE bag are a couple of the best ways. I do think it is necessary for a guy who is trying to compete to also work in a fair amount of harder sparring (80% or better), but for day to day training it can lead to injury if done too often. About 1-2 times a week is my preference. Either way, Light contact sparring is something that can be used daily and is a great way to work on different techniques, controlling footwork, feinting and throwing in combinations. In addition, light contact sparring really helps develop punch control, timing and coordination. It gives more opportunities to take risk and see if you can make certain techniques work in actual sparring, you still pay for mistakes (get hit) but the light contact lets you continue to try and "tweak" or refine those mistakes without ending up flat on your ass taking in a view of the gym ceiling..... The clip below may better demonstrate what I am describing. I am working on some light sparring with a couple of guys who are starting to compete in both Ammy Muay Thai (European rules, why you dont see knees/clinch) and MMA. As a trainer, it also helps you coach during sparring and better watch the student, without worrying about catching a hay-maker!

I think the trick to the DE bag is to just focus on keeping your hands and head moving and getting a glove on it, still using proper technique, but controlling your shots. I try to make sure that after i miss the bag (and i do pretty often) i keep moving my head and get back to the jab, then work from there. Either way, here ya go. Any opinion/advice/criticism/tips are appreciated, so long as they are constructive YouTube - Muay Thai, Boxing, Hand speed/timing drills double end bag.
