I have been doing military press with dumbells a very long time and I was wondering if it could be beneficial to switch to barbell? By barbell their are two types I mean. Either with the 90 degree chair under the smith machine or their is also a seated rack for military press using a barbell which I feel less comfortable doing without a spotter. The only thing that seems like a downside is with dumbells the weight is in line with your sides/head, with a barbell obviously you have to come in front of your head so you don't hit it, making it somewhat like an incline bench motion, but obviously much more incline.
