I have tried what you have proposed when I first did weights. Not surprisingly I got very little benefit from it. You sound like a complete novice when it comes to weight training, just like I was when I was doing 10-20 reps for 5-6 sets. What you are advising sounds more for muscular endurance rather then for strength, speed and power.
1 push up, pull up, squat : This load i believe is to big for introductionary training. Not overdeveloped just enough stiffness in the muscles surrounding the joint. Isometric holds are in my opinon even more dangerous (the force in the muscle is too big) Proprioceptive training should be done as well. : I agree, but not in the first month. Tell me lefty what do you think about Viruses training advice?
Really? So standing up out of a chair is extremely dangerous to your knees? This is just stupid. Isometric holds are one of the best ways to develop strength. If you think they're bad it just proves you have no clue. Explain why.
Pushups are too tough? My 8 yeat old neice can do a couple of decent form push ups but it's too much for an aspiring athlete? Body weight squats are to tough? If that was true there would be loads of injuries related to people going down to tie their shoe laces! :rofl
Yes, it's called introductionary training. I got very little benefit from it. : Again yes, the purpose is to raise muscle stiffnes, basal metabolism... After this you proceed to more meaningful exercises.
Its truth . The best way to retain speed and gain strength is to lift smaller weights with more reps.
Speed is largely a predetermined thing. Power is the combination of speed and strength, since there is not alot you can do for speed if you want to increase power you need to increase strength. Increasing strength doesn't mean putting on muscle. The idea is to be as strong as possible and light as possible to produce maximum power. Putting on excess muscle does hurt that ratio. Light weight with lots of reps is also completely pointless and is going to train your body to move slowly while making you weaker if you invest large amounts of time into it. You can increase strength in many ways without putting muscle on. You seem to think that as soon as you pick up a heavy weight that you're going to pack on a shitload of muscle?? Bigger the muscles the slower the man? Have you watched olympic sprinters at any stage? Guys like Jones, Mayweather, Pacman, Judah, Mosley etc. are all pretty muscled up for boxers, how do you explain their speed?
Then please explain why olympic lifters are some of the most powerful, explosive athletes in the world when they are moving around huge amounts of weight for 1-3 reps. Also explain how Usain Bolt can do heavy squats and still be the fastest man alive.
That is bad advice. Boxers who wish to get stronger shouldn't be doing 'bicep' exercises or 'tricep' exercises. They should be doing things like dumbbell snatches, pull-ups with weight, press-up variations etc where you are training more than one muscle group. Isolating the muscles is the wrong way to go for boxing.
Pushups are not too tough but you can injure yourself if you combine explosivnes and fetigue The dude had an injured knee. If squats are not done correctly yes you can damage your knees severely
Now you're on to a different subject. This is about why you train the way you train and why you think this way of training is a good idea.
