Here's another blog from a Milton chiropractor discussing: Hockey stretches
Remember that it is important to never stretch a cold muscle. You should always warm up before doing any pre-game stretches, and be mindful not to overstretch. Stretching should not be painful.
Important pre-game stretches include - Hamstring stretches, groin stretches and hip flexor stretches.
