Number 6: Sprints 

Sprints are great for ice hockey as they assist you in building explosiveness in skating when starting as well as the added cardio benefits and fitness. A park down the road with a level field of grass is perfect for sprint training.  Jogging to the park is actually a great way to warm up for your sprints.  Take 5 markers or something that can be used to identify where to run to and place one at your starting point.  Then every ten metres place down a marker til you have reached 40 metres.  Simply take ten large steps and you should have roughly ten metres mapped out.  See first diagram. 

Quick sprint workout:

Exercise 1:

Sprint to the 4th marker(40m) and then walk back
Rest for 1 minute
Repeat 3 times

If you have any good ones you would like to add as there are plenty more out there please feel free to comment below.  Remember to warm-up with some light jogging before sprinting for at least 5 minutes and to warm down as above with some jogging and a really good stretch.
