Question: it is adjustable height? ... it is different from other pictures (his waist an his colour are different)
Document: I got Bob for a birthday present about a year ago so I could get a good workout even on days when I can't get to the gym. The adjustable height makes him great for anyone and can simulate a different sized fighter. He isn't hard so I can punch with either my gel wraps or bare fist over gloves but I prefer the gel wraps. When I first got him I just filled it with water but the base will literally jump after a hard punch to the head. It might even tip over.
Very awesome. This guy is great for practing Krav Maga on. The adjustable height is definitely an added plus. Even with 5 sacks of playground sand in the base he still moves some so every now and then he has to be scooted back into the middle of the room. Overall though I'm well pleased with ol' Bob's resistance to punches and kicks. The material he's made of is durable yet forgiving (moreso than plastic and some tombstone bags). I'd still recommend using training gloves though.
Despite not being a traditional heavy bag, this thing takes some serious abuse and without wobble problems. The shape makes it different from a normal heavy bag by forcing you to be more accurate with your strikes.
Can't go wrong practicing on this. Get the longer one so you can practice those low kicks. It feels great to hit and hit your target spots and you can adjust the height which is great.
The xl BOB arrived with no damage and no delay in delivery. It truly is everything as advertised. The best thing I like is that my wife is 5'7" and I'm 6'4" and we can both adjust it to our height for workouts. No problems yet... thanks and enjoy.
You can't beat BOB, although you can beat on him for years. I've been doing mixed martial arts training since 1981 and can assure you that a BOB dummy is an excellent, must have training tool. It is quite different than striking on a heavy bag; just as a real human is quite different. You have to be more accurate, which is a good thing.
I wanted one for a long time and he was worth waiting for. I use it just about every day. I only have about 50 pounds in him currently and it is easy to move him. This is a pro because it would be a bear to move him otherwise from different living locations. He has taken a lot of abuse and shows no ware and its more fun than a bag.
Wow where can I start?Its life size and adjustable. so you can simulate fighting someone taller or shorter then you. The base is huge,  and when its full of water it makes this thing sturdy but it does give it a kick back so it feels real when you hit it. The body is dense and slightly squishy so it doesn't hurt when you hit it full impact with bare knuckles.
Gotta love BOB! This was a father's day gift to my husband. He's always looking for new ways to stay interested in working out. BOB XL includes the &#34;shorts&#34; portion of BOB, so you can throw in some lower kicks to the &#34;thighs&#34; of BOB. I like how it's adjustable and we can move him down a notch if I want to do some boxing too.
Several hours later you get to play with bob. The bob xl has more coverage than the regular bob (around the back and spine) so you can circle and work from different angles. LIttle hard punching the kidneys, (less material) but still able to work full force. I put all I had into Bob, he never toppled or ripped. On thing to remember if using gloves you could get some transfer on bob, had to scrub for a bit but it comes off.
Answer: no
