after sparring today (boxing) Ive been trying new things out and really wanted to get inside and spar one of my training partners up close (maidana style) and do damage.......my concern isnt getting inside or how to keep the position, but I REALLY felt like I couldn't land HARD punches. I landed a lot of short ones but for some reason didn't feel like I could land any of them harder. why is this? I will admit I was very close to him literally like maidana did to mayweather, I wanted to smother him and it worked fine I just couldn't land a big punch. do I need to create space first then punch? or is there any punching tips from close range like that that can help?
