Input:
Question: how much air it should have, can you punch it hard without hitting the middle post?
Document: Its like hitting a balloon. The base is plastic and mine had a crack that went through the middle to under so it was leaking. You cant hit it hard cause the base keeps falling over. Im not strong (5-2 and 166) and i knocked it over on my first punch.
Outer bag is too lose and when I punch, I frequently hit the inner pole. I am afraid to inflate too much and have it pop in order to avoid hitting the pole.
You can't even do a jab cross to this thing. The second punch will not connect, to flexible. The bladder is to week , I gave it a hard hit when it was coming back from the first hit and I ended up hitting the metal rods at its center. Not worth the money.
knowing that this is a cardio bag & not meant to pounded on, i figured this would be a good inexpensive option for me. it was great at first. yesterday it started leaking air :(  I was not hitting it hard, but was spending significant time using it. at first i thought it had just started to naturally lose a bit of air, so i got out the pump & filled it up again. within 5 minutes it was getting soft again and leaking air again.
This Product is only good for those who are weak beginners, The air filled bag will pop with too much force on your punches and kicks.. It claims you can do it on the box, but i found out the hard way that there's a limited amount of pressure it can handle..
This is a toy. Its a blow up bag. If you hit it hard enough you can hit the pole in the middle. This isnt for someone who actually wants to box. Terrible. Wouldnt recommend this cheap product.
This strike bag does not the stability it needs for anything more than childs play. If you try and punch the bag, you will hit the metal bar that runs through the middle of it. It will also bounce like a childs toy, and is not made for any type of real work out. Very disappointed in the product especially with it branded by Everlast.
This bag is not for hitting hard, it is for cardio only, I am assuming. I have never seen one of these bags. It is a large balloon inside a canvas cover that is being held up by a spring on top of a plastic barrel that you have to fill with water. I can not find a real purpose for it in my work out routine.
Bought the bag for my teen son and i knew the thing was gonna blow when I was inflating it. The outter lining is to loose to fill the bag as the instructions show but you have to or when you punch it you hit the bar in the middle. The bag lasted 5 minutes and the bottom seperated from the side. Cant even patch it. Unfortuneately I threw the box away and I didn't purchase it here. Big mistake.
I will start by stating that you must read what this bag is intended for and suggest you watch the video for it on Everlast.com to learn how to use it. It is for a full workout and is NOT a heavy bag. Based on the reviews it seems that many bought it and broke it or were dissapointed because they wanted it as a hard hitting punching bag. Be sure to follow the direction of proper inflation as it will seem as if it is inflated before it is.
Answer: yes
