A year-long ice hockey weight training program could look like the program outlined below.
Early Pre-Season
Players are preparing for the season and starting to build up after the off season.
Emphasis is on building aerobic fitness, basic functional strength and muscle bulk, which is called "hypertrophy".
Late Pre-Season
Players are working up to the start of the season and pre-season trials are imminent.
Emphasis is on building anaerobic fitness and maximum strength and power.
In Season
Competition is underway and players are expected to be fully functional for competition.
Maintenance of speed, aerobic and anaerobic fitness and strength and power is emphasized.
Off Season
You won the title, or you hopefully came close; time to relax for a while but you need to keep active.
Emphasis is on rest and recovery with maintenance of light activity -- cross training, light gym work.
As pre-season approaches, more regular work can resume with an emphasis on building aerobic fitness once again for the pre-season training.
