if you use resistance bands will they slow you down in the long run like weights do? because im thinking of quitting weights and just stick to resistance bands and also i no if you are to big it will slow you down, but what part is the main part that slows you down.. chest,shoulders, biceps etc..

ive gotten alot of handspeed using them from first hand expericence

Yeah I dont think it will slow you down, cuz its ur own body weight

not like bulking up with weights

weights won't slow you down if you know how to use them
