Thanks Fran and HerbM for your replies,

makes sense what your saying, when I first started training yrs ago a trainer told me that my jab wasn't strong enough and to put my weight behind it so I think unfortunately I have adopted a bad habit from then on where I step forward and try and put my weight behind the jab every time I throw it.

I agree that a relaxed punch is faster and more efficient than tensing up, I think I have reasonable technique with this on the straight right I will try to start fixing my jab atn the gym tonight.

Would you recommend using some small weights to strengthen muscles for more of an 'arm punch' jab ?

Theming the rounds sounds like a cool idea, usually I just see the red mist and gas myself out ! I will try this technique too.

Thanks again.
