If you're an athlete – or work with athletes – improving power in only the sagittal plane will only get you so far. To be truly powerful, in every direction, you need to train in multiple planes.
The crossover sled drag is an awesome tool to train in the frontal (side to side) plane. This explosive move is just like the first step that aspiring NFL players take when they test their lateral movement at the NFL combine.
Heavy crossover sled drags also train your backside like nothing you've ever done before and leave you super sore when you stumble out of bed the next day.
It never ceases to amaze me how trainees like to talk two and a half times their actual size. Only in the gym will complete newbies rant about their Ronnie Coleman-like genetics before even entering their first Mr. Akron contest.
