Again this depends entirely on the muscle you are isolating. Would front raises make any diffrence? A case could be made for strengthening the rotator cuff (which is why i do them) but equally a case can be made against it for tightening up your front delts with an uneven balance depending on how much weight you use as most neglect there rear delts. Like i said its quite subjective. I tend to use Bruce Lee`s philosphy which was to isolate the lats traps and tri`s. Equally though i work every muscle group in a balanced measure and make sure that even the forgotten muscle groups like obliques and lower abs (core) get a sound work out. BUT i do not work out with heavy weights in order for mass gains. Essentially any regime has to be taylored to be sports specific. If its not its a waste of tiime.
No question about that. If you want functional and massive strength gains naturally isolation is a waste of time. Compound is definitly the way to go. But as always it depends on what stage you are at in your regime.
Lol, I was actually coming back to make a comment about Rotator Cuff exercises. I do beleive that all boxers should do them as part of their weight training warm up, and the lighter the fighter the more they need it (due to their smaller joints).
The more I read about "modern" training methods, the more I wonder how the old timers were able to succeed with thier "primitive" training methods. I'm being sarcastic of course but I think too much is made of "state of the art" training methods. The old timers ran, sparred, chopped wood, rowed boats, did endless calisthenics and even dug ditches and threw big rocks for chrissakes!! And they fought 20-25 round fights! Maybe we're trying to reinvent the wheel too much when it comes to training. Just get out there and work for Godsakes. How much you can squat or bench means little inside the ring. Conditioning is king as far as boxing is concerned. Ali never lifted weights and he was plenty strong in the ring. Neither did Ray Robinson or Jack Dempsey or Joe Louis and they were ATG's. What works for one man may not work for another but one thing is certain...Being in good shape will always benefit a fighter. There's no magic formula...just hard work.
Training methods haven't changed so much since those days, but what we have the benefit of now is knowing a lot more about planning, training balance, etc, which provides faster improvements whilst lowering the risk of injury. Those guys were great, and would still be great in todays scene, but I have no doubt they would have been even better if they had the benefit of todays knowledge.
becuase you are training a muscle at a time, how is that beneficial for a boxer? our goals are not to try and build the oh so hard to build lower chest. our goal is to be the fastest, strongest and the fittest while remaining at our natural weight limit.
