I went through a phase in my journey where I questioned the effectiveness of the lockdown as well then I started training with Eddie not only did I feel the power and effectiveness of the Lockdown with him firsthand I also started learning seeing and feeling all the details from him in class the key thing to ask yourself is do you know the details? If so are you actually applying them? I would be pretty sure you dont remember there are also other options from the lockdown as well do your research and put in proper reps there is a reason why everyone knows Eddie is going to pull lockdown and he still kills with it!!!!!!
