Anyone else do these? I incorporated them into my routine several months ago and I have to say that nothing beats the piss out of me at the end of a workout quite like these. Just take a heavy DB and hold it like you’re at the top of a goblet squat, and then walk. Go for as long as you can, drop the db, puke, start over.
I find that the db pressing against your chest makes breathing harder, and your biceps will feel like they’re about to explode at the end, as do all your core stabilizers. Highly recommend them if you haven’t given them a shot ever.
