I need to exercise to get better ,I've full blown arthritis everywhere one morning waking up two years a go to full blown osteoarthritis.It took me all day to cut these 2x4's and screw together.Now i need to figure out how to attach the speed bag it's self.i love the speed bag.i take pictures and they come out to dark with the flash one???? I followed instructions by looking at the pictures of this platform.It's supposed to accommodate a 6'1" 300 pound man,ends up it's a foot to short so i thought and thought ho to easily modifie it and did just that. You can raise or lower it by tilting it towards you and let it drop down or push it up .screws stop it from slipping i extended the top portion so it will be high enough for me to use.Now i can't find the speed bag???Hah,i spent anther afternoon looking for my speed bag only to find the gloves,inflators and pressure gauge.More money now as i had two before i moved but was stressed out and left a lot i could not load any more.
