You know....I've dropped the ball on my off ice workout's too. Ha- my workouts in general. New Year new Challenge?
If you're looking for something skating related, I recommend Sk8strong. I have her adult workout, dynamic warm-up and the manual. When I actually get off my bum and do things, it's great. They don't require a lot of equipment and nothing expensive or hard to find.
In addition to aerobic exercises for endurance, anything that builds your core strength is going to help you. You also need strong thighs (to hold that all important knee bend position), and if you're jumping, upper body strength.
