why do most amateur gyms don't use the speed bag?

Because they're useless, well not entirely, they make you look cool if a ***y lady walks in but other than that they're shite.

 

Good for a cool down exercise maybe. But I agree there isn't much benefit to them.

People either get bored and stop using them. Or they never quite get the hang, and lose interest.

 

Speed bags are good. It just depends on how you work it. It also trains you to keep your hands up.

It's a not a bad tool, but there are better tools. I agree with that.

Old timers used to hit it once, and then again with the same hand, but with the back of their hand.

I can see the benefit in that because it trains you to block punches coming in.

I don't know......it is what you make of it.

 

I take it this was a joke/sarcasm?

 

We have one at our gym but I never see anyone use it

 

Because f*ck that noise.

 

It's a common myth that high repetition low resistance exercises build definition. Definition is merely the amount of muscle in relation to body fat.
The idea that muscles can take on a more defined or less defined 'shape' is nonsense. Muscles are gonna be the same shape no matter what. They only get larger or smaller. And doing light weights or low resistance, is one way to ensure that your muscles remain small.
I feel sorry for all the people who believe this.

 

If you're looking to build definition, or any kind of muscle, or really any aesthetic improvement, then yes, it's completely useless.

To build definition, you're much better off lifting heavy and leaning out - using cardio and improving your diet.

 

You're joking or incredibly ignorant on the subject of strength training and conditioning.

 

I agree that it can improve endurance though. Afterall, you are keeping your hands up.

Personally, I like to hit it while bouncing on my feet.
