Spar. Im pretty sure shadowboxing would improve reactions (knowing what to do and doing it quick/smooth) not reflexes but it really wouldn't hurt. You could try reflex balls (google image it) for a non violent approach.
Light weights in the hands, shadow boxing infront of the mirror with explosive combos. Resistant bands, put these on and do pad work, mirror work and or spar in them. Speedwork on the bag, focus on speed only not heavy punches. Good Luck!
Yep.. When you do double end bag work, part of it is working to get your pace and rhythm.. But, there is also the aspect of reflex that is part of working this. You might try to mix things up, away from a routine and focus more on trying to react to the end bag, rather than reacting to how you already know its going to react as you punch it.
Did you not read what I had in brackets? it explains the difference. HOW you react (your REACTION) is different than WHEN or how soon you react (REFLEXES). Last time Im going to explain it to you, if you still cant make the distinction then thats your problem.
It's a lifestyle thing aswell as a boxing thing. You'll need to play with a bouncing ball, activities like tennis, soccer against a wall and even flicking the pen about at work can improve how you react and how fast you do. If something is about to fall, practise reacting to it by picking it up before it touches the ground. If theres a leaf or something floating in the air grab the second you see it. Having all your parts in working order regarding the quality of your movements is important too.
Reflex Definition: an automatic instinctive unlearned "reaction" to a stimulus If this this thing is talking about reaction time. THEN It can be improved with practice, up to a point, and it declines under conditions of fatigue and distractions.
