Maybe this might be better for the bodybuilding sub, but I'll ask here.

Since about Sept 1 I've been doing a lot of outside yardwork. This includes using a tree handsaw, hatchet, axe, & chainsaw (which includes a lot of pulling on the starter cord)

The result has made my right side bicep and tricep somewhat bigger than the left side. As a result I'm only doing curls and tricep extensions for my left arm (and giving the right arm a rest, except for yard work). This is just until it catches up with my right arm.

Anyone else here ever do this?
