I hit the bag and pads great, when I do thai-boxing drills I look good, quick hands and explosive, or so my trainer and pretty much everyone in the gym says. When I spar I hold back alot to not injure my sparring partner, and frankly dont look nearly as impressive as when i am hitting the pads or bags. My instructor says I hold back to much and I need to explode when sparring like I do on the pads, however, I am afraid of hurting someone if I do this. Should I just get over this and let my hands fly or is it I just havent completely tranferred the striking skills i have built on the bag and pads over to live sparring successfully yet? In other words is it possible to look pretty good hitting the bag and pads, yet not be very skilled at actual fighting or simulated fighting (sparring). Is it possible that I am simply holding back to much when sparring? Thanks in advance.
