Boxing is all about how quick you can hit, with the right techniques. Have that, and you're deadly dangerous in the ring. being able to move your arms swiftly has nothing to do with how much weight you can lift.
Taking that in consideration, the fact that with punching a straight right or left, you must strech out your arm to make it straight and land your punches correctly. Weightlifting has the nasty habit of making your muscles short.

To make a comparison: Bodybuilders have short, thick muscles, longdistancerunners have long thin muscles, but both are trained muscles. Boxing keeps the middle of both. You need strong muscles who can strech. So a bit of weightlifting for the overall strength is good, that's why you don't need to lift as much lbs as you can.

Besides: it's more effectivly to do repeating movements with lbs that you can lift rather easely, you get more out of it (incl. muscle-stamina) than doing just a couple of real heavy lifting. That does absolutely nothing for you.

Again a comparison: no marathonrunner trains running the 42km a couple of times a week. He only runs that distance when he's running the marathon, in training he does no more then say 25-30 km.

Anyways, guess that's the reason why you don't see what you expected in those 30 minutes

Hope i helped you out a bit...
Cool Click ! Good post above !

The idea of building strength in the legs is very important, good strong foundation. , your CORE needs to be solid what I mean by core is your abs and midsection in general , you needs a good solid base, because your punching using the whole body, the legs and waist twist, up the power moves thru the shoulders and out thru the arms. Proper technique is vital in executing a powerful punch,

lots of the muscle guys push punch, meaning they are not very effective, they don’t get full extension because the muscle tendons in the bicep have shortened
,That why when doing weights be careful especially on the bicep curls. Use light weights and stretch before and after, and use proper technique when lifting weights. All the way down and all the way up,
