As the Bombers arrived at the Colorado University training field for day seven of their high altitude training camp, powered by Antler, they were greeted with more than a dozen shiny sleds.

Boulder may be embracing the festive season but unfortunately for the players the coaches aren’t.

While the majority of sleds you see around town are loaded with presents, these were anchored down with weights.

Paired up, the player’s had to charge their sleds up and down the length of the American football field, in a race against one another.

The grueling session forced the players to push though physical and mental barriers, with lactic acid and fatigue building the longer the challenge lasted.

Heath Hocking said the pain and exhaustion of the session would help the players improve their speed and power off the mark.

“That was tough, myself and Alex Browne set the lead early for just over half the race, but the boys with the bigger glutes came through and beat us at the end,” Hocking said.

“My hammies, glutes, everything got a really good workout.”

“The boys really worked hard throughout it and it helps when you have that competition. All in all it was a really good session.”

High performance manager, Justin Crow said he’s extremely pleased with the effort and commitment of the players during the first week of training.

“The sleds require the players to generate a lot of power and force, and we had a lot of repeat efforts which forced acouple of the boys to throw up, “ Justin said.

“The importance of the exercise is firstly the ‘out of the blocks’ power and also the ability to repeat effort. So late in a game they are still able to generate power, force and speed.”

“The guys have been fantastic this week. We’ve run hard, trained hard, there’s been some really clear football objectives which have been met by the coaches.”
