[Makra]

I'm a platinum terran player (dabbling in random) and I've recently had quite a breakthrough by simply building nothing but marines in TvT and expanding like crazy. It's really starting to change my perception of the game and I feel it is a kind of macro training exercise, one which I wish I had discovered much earlier.

Until now I thought my macro was pretty decent, though in mid-late game it would often slip. However, by only building marines, having like 20 rax in one control group, I only have to focus on building marines, SCVs and supply depots. By simplifying the mechanics, it's much much easier for me to stay on top of macro and most importantly I've started noticing where the big holes in my mechanics are. It's also opened my mind hugely to the power of solid macro and how far from decent my macro actually is.

With this strat, I'm dominating every game I play against terrans who are at equal or lower level to me like never before. I think once I have mastered my mechanics just using marines, I can just convert barracks into factories/starports and will have (hopefully) masters level play.

Now I'm not going to go into the specifics of the build or strategy, instead I'm more interested in whether you've discovered any training exercises like this, or for the coaches out there whether you give your students any exercises like this?
