I'd like to add - pull. Use a gear big enough that you have to pull with your arms to help, that will give you tension in your whole body. Lean your butt back a bit and yank on the bars to move forward and push down, lean your bike from side to side if it helps. Don't put too much weight straight down on your hands though, it will feel wobbly. hth.
Winter riding is much less about badassery and much more about bundle-uppery. - malkin
