Well if I could only pick one exercise to do this next year. Have to agree with others here, the Deadlift. As much as I love getting in the squat rack, nothing compares to the overall feeling of pulling a crap load of weight off the ground. From your legs to your shoulders and all in between the DL hits them all.
Not to mention it helps in building that massive trap look I so crave. HAHA
