Terriers on sled runs? No, this isn't the annual Iditarod Trail Sled Dog Race across Alaska. We're talking NFL Combine training with Mike Boyle, strength coach for hockey at Boston University and one of the top experts in the field.

Boyle says, "I don't know if there's anything you can do that's better than trying to overcome an external load in a situation where you're put in that 45-degree lean."

A self-proclaimed "huge sled believer," Boyle is definitely hot on Sled Runs. If you're trying to improve acceleration as part of your speed training, don't leave the Sled Run out in the cold.

Besides prescribing them for his BU Terrier icers, Boyle incorporates Sled Runs into his NFL Combine training program to help bridge the gap between running drills and weight room exercises.

Sled Runs
• Load weight onto sled
• Stand behind sled and position body at 45-degree angle
• Fully extend arms and accelerate

Reps/Distance: 6-8 reps for 20 yards
Coaching Points: Drive into ground with your legs as hard as you can // Fully extend your hips, knees and ankles on each stride // Take long and powerful steps
Boyle: It's perfect acceleration position. The back leg is extended, the front knee is flexed, the body is exactly where it should be. That ends up being our conditioning for the day, and sort of a reinforcer of what we're trying to get them to think about in sprinting.
