This double kettlebell complex workout will challenge you physically but it’s not too bad mentally. You just have to remember to keep your power output high for the double kettlebell snatches. You will however feel your upper back, shoulders, and even your biceps (from those high pulls) tomorrow. This will make you suck wind, jack up your heart rate, and generally make you hate life. Kind of. There are worse double kettlebell complexes. And they’re coming.
